fill in all the ashes, serving europe to saver bureau, back in 60 minutes. if you ever have to cover up a murder, the best way is to make it look like an accent. raring to the streets of the invasion which is smelled. do you remember from childhood days? you might look across? no, no, carrots. my mom isn't a mazda ok. here it is. vince nice smell when you opened 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 on crew smell of bunk food and vanished

allison. i like the air in the mountains with the moisture troubles now. quite take a little too much and how do you feel any smell that it feels like home? what do 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 often smells in your childhood,

you're immediately transported back to it and the contents it would fit into a level to investigate exactly how sense influence on brain, newman, biologist, you can call my on his team, conducted an experiment 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 claims groups of papers. 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 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 who 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 the new information. 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, processing it from the house and, and that's where sense comes into play would 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 it has the long term memory more deeply at least not the theories and sleep

also plays a crucial role experiments and a sleep devora tree. i've 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 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. and mystery brainstorm shows that smells, can activate the hippa 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 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. 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 fragments is 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 and risk states. the imagine, see, similar to when danger lose, the brains go into overdrive sending out a cocktail. if different, new, or transmit is that stimulates all senses and ignite a firework, of intense feelings. in the 1st phase of falling in love, a blog 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 to the kettle 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 the i thought we do commit to long term partnerships and our team to help each other out . that's because we've 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 like 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 the one say home. just young kinds of is a new really 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 to test 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 for this high speed or the most. so we had to find

a stimulus that could evoke powerful emotions and come when i remember, cuz he's got to be a good form. and one way we found him doing that was the place in a seizure mask on the test person. and then introduced various smells through the mask during the scan, and i'm going to 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. so with a physical reaction, if the smell is repulsive fios and 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 discussed was reactivated activity and then they in see they really feel their stomach contracting. for example, somebody, me the magnitude, or they sense the unpleasant tastes or smells and

a gooseneck out. would that cause they sure, and the insane the knowing how bad we feel when we have 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 of dna dining down so called risk genes, which would otherwise promote inflammation or chronic conditions like cardiovascular disease, cancer or dimension. so choices of remaining healthy increase 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 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 an ice stick to. 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 psych 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 actively 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 to sit in 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 on. they only do it when they want to know done mid to 15 minutes here in volume. another surprising findings, we can old regulate on level of empathy according to the response to meet it. hello, did you burn yourself? depending on the situation. i'm the on your let's go 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. and these like they could keep for 6 years, 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, and they just math test. on the 1st go, they found the heart of the slot. so more money the candidates gave away. once it's constant, 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 tape the 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 are networks tough 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 to 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 posts as only instructions the simple daily task of going to the market to get for street was something that gap gian really missed. the 40 year old was less paralyzed off your 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. out 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 uh, yeah, great schools. get gian comfortable, perfectly. that he can do things that were until recently, impossible for him. with a walking age he can stand, woke, and even climb stairs through training. his movements are improving from day to day . listen, you are 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 this and 5 the brain to a 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 says the head physician. these are few, those of 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, island 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 pets 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 have been in 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 contracts the day before the procedure. do you 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 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 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 piece 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 via 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 it long testimony tooling. numerous parking, some sufferers 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. 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 mid to long term. for an annoying, i understand them. the treatment is working for teams. idol. he is back in the hospital 8 weeks later,

for minor tweaks and neurologist daniel 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 just to uncontrollably. uncontrollably. hold you on like that again. my legs are starting now. one thing and i'll switch the simulator on again. and the tremor disappears with the flick of a switch. let's. it takes you a 2nd source when you switch it on or off, the effect is immediate. on like tablets that and take a long time. my upside, i'm really pleased. it's worked for me to have something that jim sidle jim right meekly again. i can easily eat and work in the garden with his wife 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 tools 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 go back on quality of life. we still have plans ahead of us and he's so young and so you would have been a shame if you haven't done a shot events, enough missed you must 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, and then how have you been likely? uh, i've had to take much less medication. the tremor is really diminished. that's gonna be negative on the doctors can access his implanted pacemaker from the hospital. of

course data security has to be very tied. as i said, i'm going to my desk. so we could slightly increase the stimulation level today, and that's kind of i can do this right now by a remote control. yes, let's try and my stuff. that's mostly that. okay, then i'll do it. you won't notice much, but i've switched it from 2 to 2 point one. do you feel? all right? yeah, yes. i think it's working. 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 tunes idols, quality of life, along with it. let us read, why do you have a science question or send it to us as a video, text or voice message? if we onto it on the shows, we'll send you a little surprised as a thank you. come on just task
