What is 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, today. There is symbol and 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, thats and plays a very special role in learning. So we by, you know, as many dates will come when we learn vocabulary or anything we learned in a specific context. When, when is keep flipping smells something that you often smelled in your childhood, youre immediately transported back to it and the contents of what fits into a level to investigate exactly how sense influence on the brain. Nearby outages to you can call my on his team, conducted an experiment is 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 plain scraps of paper. Those who are 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 category. The team observed that the sense proved especially effective when the autism and spot and the time pressure that decides when theres not much time or theres just a lot to learn. Theres sent appears to act like a kind of brain booster helping it retain as much as possible in this month to move on to some of the study participants were exposed to the rose cent, not only while they studied, but also while they slipped. The research has wanted to know if this would help the brains still move the new information. Funding 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 doesnt . And beyond that, can external factors influence this Decision Making process here for an hour and, and thats where sense comes into play when i come to, to fits. Thats because sense can influence the brain while were sleep, or learning specifically to compass which mediate 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 also plays a crucial role experiments in a sleep. The board tree have shown that during the deep sleep phase, the brain reorganizes that these parts of what it is learned on decides which information is moved into the long term memory. Sense effectively we activates what was meant during the day when these and then when what was learned is reactivated into the brain. The probability increases that it will be consolidated. It can only be 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 to say nerve cells activated. So what were ready 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 doesnt protect against guessing. The effect doesnt appear to be known to. However, it definitely can help with show 10 vocabulary learning. But why roses . Its 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. This thats why we and many other colleagues use rose fragrance because of the original study uses rose fragrance of a. But im firmly convinced that other fragrances also work. But that has to be shown, of course, in further studies. So its possible that lavender posted trust, 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 vocabulary learning skills. Or 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. Its a sensation that puts up bodies interest stations. Imagine, see, similar to when danger lose the offerings go into overdrive sending out like hotel 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, applaud is flooded with a gentleman. Thats the same hormone thats 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 pushed 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 its produced through physical contact. Theyll come in and sarah tonin known as the happy hormones are of course both positive being in love. But in the early phase also are totally in levels of him slumped to 8. For example, when intoxicating happiness tends to desperate loaning, 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 cocktail 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 of the says of home in 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. Thats because with social creatures who did arrive satisfaction from supposing each other. Researchers have identified specific parts of the brain that enable us to feel empathy. I found 20 years yesterday, bridge minded folks on. Ive been strictly schematic because my research has shown that we are all fundamentally empathetic people very much so in new jersey to soon when ever the situation young, we simply feel what other people feel attached to the. And 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 john 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 preventative experiment. First voting to us to undergo an m r i scan. So it has things you want to understand how our brains enable us to empathize with other peoples feelings. Countries we needed to be able to trigger certain emotions during the scan and pull this high speed or get most of them. So we had to find a stimulus that could evoke powerful emotions. And con, when i remember cuz hes got 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 introduce various smells through the mask during the scan. And im thinking most go Chain Reaction in our range that when mostly unaware of within many seconds, we register whether this model is pleasant or notes. And we respond accordingly also with a physical reaction. If the smell is repulsive, the automatically put a fake, some want to leave stomach tract Running Stream cases. We might even throw up it was these kind different pulse it smells christian ties is tested. Im the one smell that works really well is blue, t rec acid is it really smells like butter thats gone. Really rancid. Google nice in the next run, the test participants, just the videos of people looking disgusted without smelling anything for themselves. The procedure, whats shown here is what happens when the test participants smell something unpleasant themselves get kicked up the so called in say there 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 twos guns on top of each other b i b as in white show what they call relate then come on you, you can see how a part of their own experience have discussed was reactivated activity. It said then the in see they really feel their stomach contracting. For example, somebodys clean the magnitude or they sense the unpleasant taste or smells and it gets smack out. What would that cause . They sure. And the insane, the knowing how bad we feel when were in pain. We have an automatic edge to help. The brain rewards us for them. When we do something good, it releases the whole names. They lower stress levels and strength and already means systems that even effect. So 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 dont seem to have any sense of entity. So theres 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 pads from high security jails and also because of the investigator 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 you psychopaths do the terrible things they do because they just can feel pain in thinking kind of 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 actually imagine themselves in the place to civic 10. He was currently experiencing pain. Suddenly the brains responded, just like those of the, of the test participants. That they come, the goodness, the single one of us that made us realize that the problem is not that psycho pads. So run able to empathize. Its just that they dont empathize spontaneously. They only do it when they want to know done mid to 15 minutes, feeling volume. Another surprising finding. We can old regulate on level of empathy according to the response to complete it. Hello, did you burn yourself . Depending on the situation on the, on your thumb. Hopefully thats gonna include that christy on kaiser is now studying whether its 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 is or they could give some of it away. Right. Every year they gave away the slap would be 110th less painful because of that test. On the 1st go, they found the heart of the slump, the more money the candidates gave away. Once, once its gone, then we measured how that behavior changed. Because when i use the magnetic stimulus to disrupt the activity in the so matters sensory quartets and teeth ends and lots of things organize can call, takes a touch through it. Thats 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 couldnt differentiate the pain anymore. So several parts of the brain, the 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 youre feeling better, ask you to them, getting them. Empathy 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 st. With something that get to you on really messed the 40 year old with 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 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. Its 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, you are scientists of being 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 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 gait. Escape, i will send updates in this with paraplegic center. The research is being followed with great interest. Its not yet secure, but its the best possible technical solution says the head physician. These are few, those of phoebes is concepts. The concept within this development is fantastic to close time to come to i believe its the future, at least until we have a therapy with which we can heal spinal cord injuries, island can assist you. Its definitely new and exciting and will trigger a great amount of emotions amongst our patients. So houses and buyers and puts in to this new concept. Harolds 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 parkinsons. The treatment can reduce, trim is and muscle rigidity using electrical stimulation. Many patients who suffer from the disease have benefits jims idol is conscious during the operation to implant electrodes into his brain. The surgeon needs him to respond and speak. Zydeco was diagnosed with parkinsons in his mid forties. Despite heavy medication, his tremors wont go away. Hes hoping deep brain stimulation will help. It sits on as we can see, the tremors very clearly. Now were going to stimulate individual contracts the day before the procedure. He went down for a walk. Hes not scared. He just longs for the tremors to stop. You can see how much im trembling to that im not shivering due to the cold. Its 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 guy parkinsons forced him to cut down his working hours. He cant 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 back at tubing into 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 legal does on those movements are now being recorded and stored. Its like a long term monitoring fee and hes on long testimony. Totally. Numerous parkinsons sufferers have already under gotten this procedure world wide. It almost doesnt draw any blood. Tiny holes have to be drilled into this go for the electrode implants from there on its 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. Were 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. Jim sidle has to continue to raises on the system because of 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 tim side will can finally sleep. Under general anesthetic, they connect together the cables under his skin and implants, the brain pace maker below his collarbone. A 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 patients condition by collecting data via smartwatch. Definitely technology now gives us access to a constant stream of information. From what we know about daytime fluctuations, if 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. She 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 an out trembling a lot more. If its too uncontrollably. Uncontrollably told you are like that again. My leg is a starting now. One thing im so switch the stimulate are on again. And the tremor disappears with the flick of a switch. Thats 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. Upside, im really pleased. Its worked for me to have something else. Jim sidle can write neatly again, i can easily eat and work in the garden with his wife the others, because i dont have to take care of my parking students anymore. And i can look after myself and plan and didnt 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 since i enjoy the fact that i can team is wife or even planning a trip on a tim, the elbow to but the procedure doesnt 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 lets go back on quality of life. We still have plans ahead of us and hes so young and so he would have been a shame if he hadnt done a shot events. Enough, michigan must it to another huge benefit. He doesnt have to go to the hospital as much anymore is brain pace maker can be adjusted remotely. How if youve been likely uh, ive had to take much less medication for the tremor is really diminished. The negative on the doctors can access is
