the europe, to save your romance. 30 minutes on things w. these places in europe are smashing the records, stepped into an old adventure. it's the treasure map for modern globetrotters. discover some of us record breaking site on google back to and now also in book form. and vision, which is mal, do you remember from childhood days? the smell of grass? no, not carrots. my mom is around mostly. okay. who is vince uh, nice smell when you open the window on a summer morning doctor, it's been raining of good things to the swimming pool swimming pools and the smell of chlorine phone crew, a smell of dunc food, and venice policy,

one 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 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, a nice smell wonderful. on that frequency can also help you learn new vocabulary. according to a gen and 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, by, you know, it's been dates will come when we learn vocabulary or anything we learned in a specific context. one is keep flipping smells, something that you often smells in your childhood. you're immediately transport it

back to it and the contents of it fits into a level to investigate exactly how sense influence on the brain. newman biologist, 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, how to sent it overload, filled with dried rose petals, the control group, unscented on the loops filled with plain 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 sense proved especially effective pointing to participants button to time pressure. 15 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 were exposed to the rose center,

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'd be interested in 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 that's where center comes into play when i come to to fix it. that's because sense can influence the brain while we're sleep or learning specifically to shape a compass, which mediates between short and long term memory proceedings. miles is directly connected to the compass. information of sold the same time, 10 inches long term memory more deeply, at least not the theories on sleep or so he plays a social roles and experiments and

a slightly lower tray 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 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, of a category 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 road cent so that the results could be easily compact. this event is why we and many other colleagues use rows fragrance because of 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 of how the brain stores information in memory and processes it at

night button. and then the next time someone gives you roses. they can also help you vocabulary 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 word is love. it's a sensation that puts up bodies interest stations. imagine, see, similar to when danger lose, the brains go into overdrive sending out. so like hotel is 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 buffer flies and you'll stomach it causes ops, you polls to die late. the body is push on or not causing blood pressure and pulse to rise. meanwhile, oxy towson helps with funding and developing trust oxy. towson is often dep cuddle 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 learning, when was 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 are keen to help each other out. that's because with social creatures who derive satisfaction from supposing each other's researches have identified specific parts of the brain that enable us to feel empathy. i found 20 years yesterday bridge monday, the 1st one i've been strictly schematic because my research has shown that we are all fundamentally empathetic people very much so in youth,

as it said soon when ever the situation. and we simply feel what other people feel like test here. basically to find 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. and even though it's a 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 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 needed to be able to trigger certain and emotions during the scan. and cool thing. got this high speed the most so we had to

find a stimulus that could be vocal, powerful emotions and come when i remember to reach out to be a good form. and one way we found that 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 thinking most trigo chain reaction in all range that were mostly unaware of within many seconds we register whether this money is pleasant or not. and we respond accordingly also with a physical reaction. if the smell is repulsive, we automatically 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 kinase is tested. i'm the one smell that works really well is blue teoric acid is it really smells like butter that's gone. really,

ranch and golden lice in the next run, the test participants, just those 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 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 here. you can see how a part of their own experience of discussed was reactivated activity. it said then the in seen they really feel their stomach contracting. for example, somebody in magnitude or they sense the unpleasant taste or smells and it gets

smack out with activation. 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 strengthen mean systems that even affects salt 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 but some people don't seem to have any sense of entities to others at all, pursuing causes studies this going to want to 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 investigative dodd. 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 as long on the tune for an ice deep. so. 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 of 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 actively imagine themselves in the place of the victim he was currently experiencing pain. suddenly the brains responded, just like those of the sophie test participants, that they can be a good man. the single one of us that made us realize that the problem is not that

psycho pads, so we're unable to emphasize. it's just that they don't empathize spontaneously on . they only do it when they want to know done it to finish the material volume. another surprising finding, we can old regulate on level of empathy according to the response to read it. hello, did you burn yourself, depending on the situation? i'm the on your let's go on cool. let christy on kaiser is now studying whether it's possible to help people with mental disorders become more empathetic. tea already succeeded in doing the opposite. in another study setting that entity can be suppressed. because it 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 euros each and said they could choose what to do with it. 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, because for that test, on the 1st go, they found the hard as a slap. the more money the candidates gave away. when jets con, then we measured how that behavior changed. when i use the magnetic stimulus to disrupt the activity in the some matters sense record, texas, it ends in lots of things organize, can call, takes it touch through it. that's the part of the brain that receives pain, even when just watching it being inflicted on it. it's 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. 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 then 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 gap gian really missed. 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 the intentions. it's cool, it was the 1st time i bought something in the market while walking. so uh, 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, 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 a processing unit, and the movements among natural socratic with the pre programmed stimulation walking was much more robust and 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 reset is being followed with great interest this 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 come to i believe it's the future, at least until we have a therapy with which we can heal spinal cord injuries hyperlink. and it's definitely new and exciting and will trigger a great amount of emotions amongst our patients. so houses and by using frontier and this new concept, harold's a new era in the treatment of mode to deficits in the future. similar 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 benefits. jim sidle is conscious during the operation to implant the 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. he's hoping deep brain stimulation will help sits on as we can see the tremors very clearly. now we're going to stimulate individual contracts 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 to 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 back at to being ins, university hospital, they have long experience with deep brain stimulation. this brain piece baker 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 that line 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. they have to be implanted several centimeters deep into the brain. tim's idol has to continue to raise his arm. the system that gets all the tremor is also being measured by the motion sensors on your arm and the watch which we fitted yesterday with the well. if it gets done on the block. com,

after 4 hours the electrodes are finally in place, no team site will can finally sleep. under general anesthetic, they connect together the cables under his skin and didn't plan to bring 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'm interested in. the treatment is working for teams idol. he is back in the hospital 8 weeks later for minor tweaks. 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 i'm to switch the stimulate around again, and the tremor disappears with the flick of a switch. that's it takes just a 2nd source when you switch it on or off the effect, it's immediate. on like tablets that can take a long time. upside, i'm really pleased, it's worked for me, but that's 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, 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 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 you would have been a shame if you haven't done a shot, evans, you know, since you must, it is 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. the negative on the doctors can access is implanted pacemaker from the hospital. of

course data security has to be very tied. it was that i'm calling about that's what we did slightly increase the stimulation level today. and those 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 if that was probably have switched it from $2.00 to $2.00. 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 has improved and tunes idols, quality of life, along with it. if i was let is read, why do you have a science question? send it to us as a video, text or voice message. if we onto it on the show, we'll send you a little surprise as a thank you. come on just task the

that tool. so this edition of tomorrow today, which was all about the break. we'll be back next week with most of the stories season, and stay curious by the,
