it says stop. so one move bangladesh a go facing the country to the last, the guessing pushed back even from their own family. showed done by seeing says, home loans seeking is self determines life list of goals from drudgery and abuse. the oldest fixed on d, w, and vision, which is smell. did you remember from childhood days? the smell of grass? no, no, chicago, it's my mom. isn't a mazda ok here it is. vince nice smell when you opened the window on a summer morning after it's been raining of good things to the swimming pool,

swimming pools in the smell of chlorine phone, crew smell of bunk food and venice palace. and i like the air in the mountains with the moisture, purple smile. quite take a little too much. and how do you feel any smell that it feels like home? what did you know about the link between smell and memory? find out why we so send a mental and other secrets of the brain now on tomorrow to day. very symbol of love, and they smell wonderful on that fragrance can also help you learn new vocabulary. according to a gentleman research team, the scent of roses helps the brain retain information. my advice, just as we know, that send plays a very special role in learning. so we've always been dates will come when we learn vocabulary or anything we've learned in this specific context. when, when is keep flipping smells something that you of and smells in your childhood.

you are immediately transported back to it and the contents of it for fits to fit into a level to investigate exactly how sense influence on brain, newman, biologist, you can call my on his team, conducted an experiment or a 165 test subjects were given envelopes and how to study japanese vocabulary for 3 days. cost study participants had a sent it on the field with dried rose petals, the control group, and sent it on the loops filled with clean scraps of paper. those who was surrounded by just send a rose as did best to in the vocabulary test, remember, and on average 8 and a half percent more of a cabinet rate. the team observed that the center proved especially effective when the participants buttoned the time pressure that you'd sites when there's not much time or there's just a lot to learn. there's sent, appears to act like a kind of brain booster helping it retain as much as possible this month to move on

to some of the study participants are exposed to their bo sense, not only while they studied, but also while they slept. the research is wanted to know if this would help the brain's store move if the new information responded to. so i'll be interesting. question is, what are the criteria for our brains to decide what goes into the long term memory and what doesn't? and beyond that, can external factors influence this decision making process for an hour and, and that's where sense comes into play when i come to, to fix. that's because sense could influence the brain while we're sleep or learning specifically to keep a compass which mediate between short and long term memory proceedings, miles is directly connected to the compass information of sold the same time, then inches, the long term memory more deeply. at least not the theme,

the sleeve also plays a crucial role experiments and a sleep. the board tree have shown that during the deep sleep phase, the brain reorganizes that these parts of what it is learned and decides which information is moved into the long term memory. sense effectively re activates what was done during the day when these and then when what was learned is reactivated in the brain. the proper ability increases that people be consolidated. it can only be in what exactly happens in the brain during this process remains a mystery. but brain scans show that smells, can activate the compass even in deep sleep. if the brain has already associated information with a sense during the day, the sent alone can help it to store it at night. one possible explanation, the same nerve cells activated that we're already finding when the person was awake . in order for the sense to help with learning, it has to be used in an actual test. for example,

a vocabulary test. this helps the brain access to what it is, then at least for a few days. but the scent of roses doesn't protect against guessing. the effect doesn't appear to be long term. however, it definitely can help with short term vocabulary learning. but why roses? it's actually quite random. it was the frequency used in the 1st study on the topic . latest studies also use rogues sense, so that the results could be easily compact. there's a that's why we and many other colleagues use rose fragrance because the original study uses rose fragrance of a. but i'm firmly convinced that other fragrances also work. but that has to be shown, of course, in further studies. so it's possible that lavender, both interest, for example, can also help consolidate learning. at least initial time. researches are still

figuring out how the brain stores information in memory and processes it at night button. and the next time someone gives you roses. they can also help you with cabinetry learning skills. our brains also help us feel emotions. the bose, which is a viewer from bosnia and herzegovina with a truly timeless question on this subject, the watch is loud. it's a sensation that puts up bodies interest stations. imagine, see, similar to when danger lose, the brains go into overdrive sending out a cocktail of different, new or transmit is that stimulates all senses and ignite a firework of intense feelings. in the 1st phase of falling in love, blood is flooded with

a gentleman. that's the same hormone that's triggered by exploration of stress and gives you bucks or flies in your stomach. it causes ops you polls to die late. the body is push on and that's causing blood pressure and pulse to rise. meanwhile, oxy towson helps with funding and developing trust oxy. towson is often the cut all hormone as it's produced through physical contact, documented serotonin. notice the happy hormones are, of course, also positive being in love, but in the early phase also are turned in levels of them fluctuate. for example, when intoxicating happiness tends to desperate low name when we're separated from the one we love, the studies of brain waves show that being in love especially activates the areas of the brain that are responsible for sexual edges. so can we

conclude that this homeland comp sale was only created by nature to ensure that we focus on one partner during reproduction in time of bodies getting used to the high level doses of home at the end after 2 to 3 years at the latest, the immediate thrill of infatuation is that we do commit to long term partnerships and keen to help each other out. that's because with social creatures who derive satisfaction from supposing each other, researchers have identified specific parts of the brain that enable us to feel empathy. i found 20 years yesterday freshman. unfortunately, i've been strictly schematic because my research has shown that we are all

fundamentally empathetic people very much so in new jersey to at soon when ever the situation, we simply feel with other people feel attached to the ones i basically to our western world. we tend to see each other very much as individuals, but what my research has shown is how strongly were shaped by the people around us . they should be on within the last one say home. tristan kinds, this is a neuro scientist. a lot of his research has focused on how well brains empathize with other people go. his research with quite a presumptive experiment. first thought into is for us to undergo an m r i scan. so that's things you want to understand how our brains enable us to empathize with other people's feelings. countries. we need it to be to trigger certain emotions

during the scanner coal besides the the most. so we had to find a stimulus that could evoke powerful emotions and come when i remember to reach out to be a good form. and one way we found him doing that was to place an anesthesia mask on the test person. and then introduced various smells through the mask during the scan and i'm thinking most take a whole chain reaction in our range. that when mostly unaware of within many seconds, we register whether this money is pleasant or knows. and we respond accordingly. also, with a physical reaction if the smell is repulsive, the ocean logically put a fake, some want to leave stomach contract, meaning strain cases we might even throw out it was these kind of repulsive smells . christian kinases tested. i'm the one smell that works really well is cubic

acid is it really smells like butter that's gone. really, ranch and golden lies in the next run, the test participants, just the videos of people looking disgusted without smelling anything for themselves. the procedure was shown here is what happens when the test participants smells something unpleasant themselves or get kicked up. the so called incident or is exit, which we know is involved in processing smiles. where it gets interesting is when we look and see what happens when the touch of the candidates, just see other people responding to bad smells even days. the two's guns on top of each other using white show what they call relate. then come on you, you can see how a part of their own experience of disgust was reactivated activity and then they in see they really feel their stomach contracting. for example,

if somebody's believed in magnets is, or they sense the unpleasant taste or smells and a gooseneck out, would that cause they sure. and the insane, the knowing how bad we feel when we're in pain, we have an automatic edge to help the brain rewards us for that. when we do something good, it releases the whole names. they lower our stress levels and springs and remain systems that even effects on dna, dining down so called risk genes, which would otherwise promote inflammation or chronic conditions like cardiovascular disease, cancer, or dimensions. so choices of remaining healthy increase or but some people don't seem to have any sense of entity. so there's little christian kinds of studies this going to want to understand what happens and what goes wrong

. in these cases, we worked with a number of psycho paths from high security jails and also because of the investigated job. and what we observed is that when the psychopaths watched others suffering pain, the area of the brain involved and feeling pain was hardly activated at all. on the tune for the ice tips. so at 1st we thought ok, maybe psychopaths do the terrible things they do because they just can't feel pain in painting time. but it's like us are often very good me placing people to do that. they actually have to be able to empathize quite well. so the research has told them to activity imagine themselves in the place of the victim. he was currently experiencing pain. suddenly the brains responded, just like those of the healthy test participants. that they tend to be a good man. the thing one of us that made us realize that the problem is not that

psycho pads. so run able to empathize. it's just that they don't empathize spontaneously on. they only do it when they want to know done mid to finish and maturing volume. another surprising finding, we can old regulate on level of empathy according to the response to meet it. hello, did you burn yourself? depending on the situation on the, on your thumb? hopefully that's gonna include that christy on kaiser is now studying whether it's possible to help people with mental disorders become more empathetic. t already succeeded in doing the opposite in another study setting that entity can be suppressed. besides, we will find the experiment was actually quite simple, and we showed each candidate a person being slapped on the hand on them. and then we gave them 6 zeros each and said they could choose what to do with it. they could keep the 6 euros,

but then this poor person would have to be slapped again just as hard and with what does or they could give some of it away. right? every year they gave away the slap would be 110th less painful. because for that test, on the 1st go, they found the heart of the slot, the more money the candidates gave away. once it's gone, then we measured how that behavior changed when i use the magnetic stimulus to disrupt the activity in the so matters sense, record checks and teeth ends and lots of things organize can call, takes a touch through it. that's the part of the brain that receives pain, even when just watching it being inflicted on audits. the temporary disruption to this function meant the candidates response no longer depended on the strength of the something. they couldn't differentiate the pain anymore. the so several parts of the brain that a networks have to work together in order for us to be suitably empathetic,

being empathetic, his own natural state. when we use that to help others, if you're feeling better, ask you to them, getting them good. entity can actually make us happy and content, which could help us to keep healthy. in may 2023. this story gone at global interest, a paralyzed man walking again. thanks to electronic brain implants, these devices, we quote his brain signals and send the data to a possible computer. that data has been transmitted to another implant in his spinal cord, which poses only instructions. the simple daily task of going to the market to get for street was something that got to young really missed the 40 year old was less paralyzed officer an accident 12 years ago. now he can once again enjoy this simple pleasure. the dutchman is the 1st person to receive

a new type of double implant that creates a direct and your logical link between the brain and the spinal cord via a wireless digital interface. doubt to young can control his paralyzed legs with his intentions. it's cool, it was the 1st time i bought something in the market while walking so great spears. get john comfortable perfectly that he can do things that were until recently, impossible for him. with a walking age he can stand, woke, and to even climb stairs through training, his movements are improving from day to day. listen, your scientists have been researching the technology for many years now in a fast version. that was just an implant in the spinal cord. the come on to work came from a tablets. now listen via the brain to a processing unit. and the movements a more natural socratic with the pre programmed simulation walking was much more

robotic, not very fluid. now though, because the brain directly controls the stimulation, we have a very smooth, coordinated gait. escape, i will send updates in this with paraplegic center. the research is being followed with great interest if moment yes, a cure, but it's the best possible technical solution. so it's the head physician. these are few, those are phoebe's is concepts. the concept within this development is fantastic to close time to come to i believe it's the future, at least until we have a therapy with which we can heal spinal cord injuries. island can assist you, it's definitely new and exciting and will trigger a great amount of emotions amongst our patients. so houses and buyers and puts in this new concept, harold's a new era in the treatment of maybe 2 deficits in the future. some of the technology will likely be able to restore the function of the ohms and hands as well. brain implants can also use the symptoms of parkinson's. the

treatment can reduce trim is an muscle rigidity using electrical stimulation. many patients who suffer from the disease have benefits teams. idol is conscious during the operation to implant electrodes into his brain. the surgeon needs him to respond and speak is idle was diagnosed with parkinson's in his mid forties. despite heavy medication, his tremors won't go away. these hoping deep brain stimulation will help it sits on as we can see, the tremors very clearly. now we're going to stimulate individual contracts the day before the procedure. the went down for a walk. he's not scared. he just longs for the tremors to stop. you can see how much i'm trembling through that. i'm not shivering due to the cold . it's the tremor hunt my handwriting is affected. i also leisure activities going

out to eat with my wife. some people just see me for the 1st time. think i can count up to 3, they talk down to me. so 1st thing, this guidance parkinson's forced him to cut down his working hours. he can't go on business trips, let alone run him, our phone, and the drugs that are intended to boost doping mean levels in his brain effect his mood. i want my life at tubing into university hospital. they have long experience with deep brain stimulation. this brain pacemaker can be adjusted as the illness gets more severe or symptoms change to be able to respond quickly. they have recently begun to use a smart watch to measure tremors, agility, and sleeping patterns by a sensors. on the inside of the high can see your hand is moving about and also your arm a little bit. the vehicle does um those movements are now being recorded and stored

its like a long term monitoring fee and he's on long testimony tooling. numerous parking son suffers have already under gotten this procedure world wide. it almost doesn't draw any blood. tiny holes have to be drilled into this go for the electrode implants from there on. it's a highly delicate operation. planned with c t images during the operation measurements are taken to gauge whether the electrodes are in the right place. we're going to check the shows in the region step by step 10, up to flip the switch. it has to be implanted several centimeters deep into the brain. tim's idle has to continue to raise his arm. the system that gets all the tremor is also being measured via the motion sensors on your arm and the watch which we fitted yesterday with the well,

if it gets done on the block column after 4 hours the electrodes are finally in place. no jim sidle can finally sleep. under general anesthetic, they connect together the cables under his skin and implants a bring peace maker below his collarbone. deep brain stimulation is becoming increasingly sophisticated. growing knowledge about individual areas of the brain means more precision. as part of an international study, they are now testing how closely they can monitor a patient's condition by collecting data via smartwatch. definitely technology now gives us access to a constant stream of information indicated from what we know about daytime fluctuations. we know whether things are better or worse mornings or afternoons. we know whether a patient would benefit from an adjustment in the mid to long term. for an annoying i understand them coffee p at the treatment is working for teams. idol. he is back

in the hospital 8 weeks later, for minor tweaks and neurologist down your advice switches off the brain piece. baker 1st to see how bad the symptoms are without any correction. yes, your right hand is now trembling a lot more is to uncontrollably uncontrollably. hold you on like that. again, my leg is starting now. one thing, i'll switch the simulator on again. and the tremor disappears with the flick of a switch. let's. it takes just a 2nd source when you switch it on or off the effect just immediate on like tablets that can take a long time. my upside, i'm really pleased. it's worked for me to have something to jim sidle can write neatly again, i can easily eat and work in the garden with his wife the others because i don't have to take care of my parkinson's anymore. and i can look after myself and plan and enjoy my leisure time goodness. and i can do my chose again. i can also use

a chain, sorry to cut down a branch, but i prefer to do it by hand, but some stuff i enjoy. the fact that i can team is wife or even planning a trip on a tim, the elbow to but the procedure doesn't work as well for everyone. deep brain stimulation can also cause side effects, just like medication symptoms can persist or return. but the 2 of them just want to look ahead let's go back on quality of life. we still have plans ahead of us and he's so young and so he would have been a shame if he hadn't done a shot events. enough, michigan must it to another huge benefit. he doesn't have to go to the hospital as much anymore. his brain pacemaker can be adjusted remotely. you know you how if you've been likely. uh, i've had to take much less medication to the tremor is really diminished. the negative on the doctors can access is implanted pacemaker from the hospital. of

course, data security has to be very tied as, as i'm content. that's what we get. slightly increased the stimulation level today and those comments i can do this right now. fire remote control. yes. let's try some money stuff. that's mostly that. okay, then i'll do it. you won't notice much if i have switched it from 2 to 2 point one . i'm, do you feel? all right? yeah, yes. i think it's working on electrical impulses relayed via remote control just a few years ago. that would have been science fiction. today. it's reality. this technology is improved and teams, idols, quality of life, along with it. let us read, why do you have a science question? send it to us as a video, text or voice message. if we answer it on the shows, we'll send you a little surprised as the thank you. come on,

just task the. that's all so this edition of tomorrow today, which was all about the break. we'll be back next week with most of the stories. see event and state curious by the
