the good i wish i could have done more to save. you just click away, find the best document on you to really see the world as he's never seen it before. the drive now to dw the and vision which is smell. do you remember from childhood days? you might look across? no, no, carrots. my mom is around mazda. okay. who it is. vince uh, nice smell. when you open the window on a summer morning doctor, it's been raining now, which seems to me 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 is the 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 that 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 often smells in your childhood. you're immediately trans, put it back to it, and the contents of it fits into

a level to investigate exactly how sense influence the brain. newman biologist, to you can call my on his team, conducted an experiment. for 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 move a capital rate, the team observed that the center proved especially effective when the participants button, the time pressure 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 sent,

not only while they studied, but also while they slept. the research is wanted to know if this would help the brains still move if the new information responded to fill out. the 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 and for an hour and, and that's where sense comes into play when i come to, to fix. that's because sense can 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 and has been long term memory more deeply. at least not the theories. and sleep also is a crucial role experiments and

a sleep devora 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 reactivate. so what was that during the day when these of them, 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 st 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 forgetting. 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. 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 figured know 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. watch is love. it's a sensation that puts out bodies injury 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 of flies and you'll stomach it causes ops you polls to die late. the body is push on that, causing blood pressure impulse 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, known as the happy hormones are of course, also positive being in love. but in the early phase, also are turning levels often 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 we've social creatures who derive satisfaction from supposing each other. researchers have identified specific types 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 what other people feel like test here are basically to even 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 the, on one say home. just young kinds of 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 provocative experiment. first thought into 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 able to trigger certain emotions during the scan and pull think of this hi steve of the most. and 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 scam and i'm trying to get 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 tract. i mean stream cases we might even throw up it was these kind of repulsive smells. the christian kinase is tested. i'm the one smell that works really well is cubic acid is it really smells like butter that's gone, really rancid. couple of nice in the next run,

the test participants, just the videos of people looking disgusted without smelling anything for themselves. the facility, what's shown here is what happens when the test participants smells something unpleasant themselves 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, given days, the two's guns on top of each other using white show what they call relate and come on you, you can see how a part of their own experience of discussed was reactivate, activity and then they in see they really feel their stomach contracting. for example, if somebody can demography or they and see unpleasant tastes or smells and then

just make out what 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 entities to others at all. christian and kaiser studies this going to want to understand what happens and what goes wrong. in these cases, we worked with

a number of psycho pads 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 or so at 1st we thought ok, maybe you psychopaths do the terrible things they do because they just can't feel pain in painting time. but psych, a us are often very good manipulating 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 come, the good man, the thing, the one of us that made us realize that the problem is not that psycho pads. so

we're unable to empathize. it's just that they don't empathize spontaneously. they only do it when they want to know done mid to finish the material 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. if i do 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 euros 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 slump, the more money the candidates gave away. once, 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 it touch throughout. 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. 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 the i'm getting the entity can actually make us cookie and contents, which could help us to keep healthy myself 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 is 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 messed the 40 year old was left 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 new,

or electrical 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 the right spirit, john comfortable perfectly. that he can do things that were until recently, impossible for him. with a working age he can stand, woke, and 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 ons to walk came via a tablet. now this and by the brain to our processing unit, and the movements a mo, natural socratic with the preprogrammed stimulation walking, was much more robotic, not very fluid. now though, because the brain directly controls the stimulation,

we have a very smooth coordinated gate escape and we'll 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 go to i believe it's the future, at least until we have a therapy with which we can heal spinal cord injuries. highland can assist you, it's definitely new and exciting and will trigger a great amount of emotions amongst our patients. so houses and by using 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 and muscle rigidity using electrical stimulation. many patients who suffer from the disease health 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 the citizens. we can see the tremors very clearly. now we're going to stimulate individual contact the day before the procedure. he 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 hunter, 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 talked down to me that 1st the skype and parkinson's forced him to cut down his working hours. he can't go on business trips, let alone run them, our phone, and the drugs that are intended to boost doping mean levels in his brain effect is moved. i want my life active at tubing into university hospital. they have long experience with deep brain stimulation. this brain pace maker 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 his sensors. this is inside of the how you 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 it 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 and the regions step by step 10, up to flip the switch. they have to be implanted several centimeters deep into the brain. tim's idle has to continue to raise his arm the system because 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 the brain pace 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 made to long term suspicion and annoying items to them for. the treatment is working for teams. idol. she is back in the hospital 8 weeks later, for minor tweaks. neurologist down your advice,

which is on the brain piece, baker 1st to see how bad the symptoms are without any correction. yes, your right hand is an out trembling a lot more just to uncontrollably. uncontrollably hold you on like that. again, my leg is starting now. one thing then, i'll switch the stimulate around again. and the tremor disappears with the flick of a switch. it takes you a 2nd, so when you switch it on or off, the effect is immediate. on like tablets that and take a long time outside. i'm really pleased. it's worked for me to have something that jim sidle can write neatly again. he can easily eat and work in the garden with his wife the others, because i don't have to take care of my parking suits anymore. and i can look after myself and plan and didn't join my leisure time. and i can do my chose again. i can also use a chain, sorry to cut down a branch off this,

but i prefer to do it by hand. but i enjoy the fact that i can team is wife or even planning a trip on attend alberto. 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 you haven't done a shot events, enough misconduct, it to another huge benefit. he doesn't have to go to the hospital as much anymore is brain pace maker can be adjusted remotely. how have you been likely? uh, i've had to take much less medication. the tremor is really diminished. okay. then you guys have on the doctors can access is implanted pacemaker from the hospital.

of course data security has to be very tied. 2 of them couldn't, but that's what we did slightly increase 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. 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 kittens, 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 officer 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
