the spots, the cities check on some great cultural memorials to boot w travel. we got the, it's quite a hard work are the most complex, oregon in your body, the brain, an amazing oregon that continues to develop and learn across the life span. so what can you do to keep your brain fit? what's going on if you have a kind of a lightning storm in your brain? and how does the brain actually work? check it out on in good shape. the, for the brains, 170000000000 workers. it's a day,

much like any other the hands of neurons touch the feet of other neurons forming synopsis. that's how they communicate. meanwhile, lyle sounds supplying them with nutrients and fluids. nobody suspects yet, but the piece will be short lived. deep inside the brain is the sound limits, kind of really station for most sensory information. unimportant details gets swept onto the table. but suddenly panic breaks out the highly strong, a mid july head spotted something that are focused on plants and emotions. and the hippocampus starts calling up bad memories. just in case the hypothalamus prepares the body to make a run for it by instructing the pituitary gland to pump chemical messengers into the bloodstream. gradually the news spread throughout the entire neurological complex. and it's pro says via

a wide range of different departments. the visual information is examined in detail. options for averting danger are analyzed. the motor cortex starts working on an escape plan. the language experts gets busy trying to name the spider specie. other departments are trying to assess the situation. how are people around us reacting? maybe the spider is actually kind of cute. what other options are there to deal with? the situation meanwhile, and the pre frontal cortex, the boss was sitting in the executive suite. but it's hard to say exactly who is making the final call. as is often the case, a lot of units are involved and good decisions are usually down to teamwork. it takes less than a 2nd to react. the motor cortex initiates movements signals are transmitted from

the english department, the brain stem, through the spinal cord to the rest of the body. the lungs are instructed to take a deep breath. and then it's the cerebellum to turn to shine. it's where complex sequences of movements are trained and precisely coordinated with the help of a pincer grip, the spider is cramped by a leg and transported into the card. the danger has been the but the next drama is already throwing just another long and strenuous work day in our brain. so many processes are still in mystery. this is one company that doesn't come up with the secrets easily. exercise makes you happy and it's great for your health, but is it also good for your brain? a recent study showed that even small amounts of regular physical activity gives

the parts of the brain responsible for learning and memory a long term boost. but what about its immediate benefits? for example, when you're studying for an exam, imagine you spend the day in front of your computer studying. now it's crunch time just a few days left until your exam. working hours would clearly be a waste of time at that point because the more you studied, the better you'll do on your test, right? well, that's not necessarily true. exercising actually improve the exam performance. let's explore the science behind that. even though exercise seems like an extra burden, it can actually has, believe you stress whenever you feel stressed out, the sole cause hypothalamus between 3 as an axis is activated. it is one of the

major stress response systems in the body. it connects to central nervous system with the endocrine system and regulates the secretion of the stress hormone called to solve. the problem is that when your body releases a lot of got this on your performance and concentration degrees, this is where exercise comes in handy. it's reduced because it's on level making you feel less stressed immediately. exercise also comes to h b axis and makes you less scared of the upcoming exam. in terms of energy levels. again, it's counter intuitive because you're tired, right after doing a moderate to baker if exercise, right? but if you wait about a half hour to an hour, you will notice that you have more energy to do your day to day activities that you're more alerts. not the upside is that the physical activity

hopes up your brains production of the feel good and you to transmit this or the end. often, you notice a mod boost and simply feels better. and that's a great time to start studying again. when the body moves, blood flow in the prefrontal cortex increases, which helps with the executive functions. and that's just an umbrella term to describe things like our problem solving ability or ability to switch between tasks. our ability to selectively focus on the task that we're on and ignore all the distractors in our environment. exercise allows you to focus more on studying and memorizing formulas. for example, which means disruptions like an incoming phone calls. want to distract us much. but exercise doesn't only can be focus better, it also helps you learn more any less time. it also improves our processing speed,

so that the speed with which we're able to process the information that's presented to us. and because we're able to attend to information better. so we're able to pay more attention to the things we need to focus on. we're able to learn it better. exercise also promotes neuron growth in the hippocampus, which is responsible for long term memory. studies have shown that physical activity has positive effects on academic performance. but how would you get started during a stressful exam period? if you already work out a bit, tried to stick with it even during exams, it's not stuff that you choose a form of movement to actually night. it can be as simple as walking briskly, playing volleyball are doing at aerobics at home. any physical activity that increases your hot treat makes

a difference. you'll experience an energy boost of to the single workouts available . if you manage between $3.00 to $5.00 times per week, the ethics will be even greater side se strive to create a routine. but even if you can't, anything is better than nothing. last but not the least, it's important to exercise moderately, not to handle competitively during exam period. working out shouldn't create additional performance pressure that will help you find the plastic balance between exercise and focused study time and you use your exams a do you have a passion for science and health? check out dw science on tick tock. are we really what we eat and what's the link between happiness, hormones, and healthy relationships is the caffeine and coffee really addictive. and what are some more great health packs that can help you as your exams

find the answers, gets more on dw science, our tech talk channel sleeping well is key to keeping your brain happy, healthy and alerts. when you sleep, your brain doesn't just switch off. it's doing all sorts of important work, like sorting and storing the days, input and information. without sleep, we wouldn't be able to learn or remember a thing and sleep researchers keep finding out more about what's going on while we sleep. the switch mountain top to the north fittings for me. i sleep scientist, christina bloom is making her bed for the night. the

soft is his dad. so stands ending. we spend about one 3rd of all life in the state of sleep and talked to him and said, yeah, most of us don't know what happens when we're in the state for blog. and we have some information to gain because it's a states of unconscious moment in dfcs heights kind, but we're fine. have them. and then others and switched out. it's also crucial to somebody for if this is and is as my impulsive life is wakeful, notice about fine. that's why i find sleep safe estimate touristy fast enough to into stops of 2019. she began researching sleep at the university of basel. i just knocked out the history again. i do love to sleep myself and i usually sleep very well unless i have to work in the sleep. thoughts with me still in the sleep lab, christina bloom and her colleagues study people who suffer from sleep disorders. this involves measuring their brain activity while they're sleeping, the

live, you just even reach the voice we might be on teach us, but that doesn't mean nothing is happening cuz he has been getting quite the opposite. and there's lots going on in the brain and the whole day when we sleep office funds. and here, for example, we know that metabolic products that will build up in the central napa system during the day of flushed out at night. so i've gone with those sorts of cleansing, attaches enough. our special image on the screen is by this one, the highest even put says that it is now 2000 and we know the telling you right. and the level you think tracers of the memories from during the day a transfer or long term memory types where they can be retrieved and used to come enough 1st, because as a learning aspect, that aspect of the ad, that's one reason why sleep is important. the visiting christina, blue mentor team are trying to find out which factors influence sleep and how they conduct a series of experiments with test person's changing one variable each time the

being positive. protecting nearing basel with. are you interested in the role type by lights with tax that you like to also also official? like, especially in the things i often administration staff wants to test subjects, the researchers record their brain activity within each and identify and evaluated their sweet stages to lodge and slow waves to pick the deep sleep phase which is essential for restorative sleep. but which specific factors make sleep restorative? that's what christina bloom wants to find out. loud with us about 15 minutes, i'd say that so many people that you like, especially if i'm not true daylight outside i is one of the most underestimated foxes. when it comes to a good night sleep, i want to make sure we want to know how much day like you need for it to have a significant positive effect on sleeve at the end of this month. i'll finish off

the hop. so for now we don't know the costs in our, in the morning is enough, or it's an hour is better than design. is a case of the more the best to email or is there a point where the benefit plus tires fact ones hoping to can kind of get off the 5 . hopefully we'll be able to give people some idea about how they can make the motion to stabilize the, to improve the sleeping has to be all, am i talking about some kind of stuff to focus on inside of support? austria, christina bloom, a has discovered the joys of mountain hiking for her current project, she's studying the impact of the outdoor activities on the body clock and sleep patterns to get us to talk to you and ask you. so the king raises my energy levels and helps me rel, i'm tired of one is to so i think that's because it's rascal right from the daily grind. this is seizures is like logically it gives you some distance from day to day line and find that the something else and they constantly on. and so you need

to concentrate on the partisans, especially when it's narrow and winding or you have to climb for the frequency on top of your request and lots of concentrations. so you don't even have the mental space to think about everyday thing on stuff isn't they're not on important aspects of relaxing. that's where they can being physically active. it's important to me to see when we have all kinds we see the contrast sufficient hasn't left the need to be as common. charles, it's when day and night. hopefully bigger will sound like deep valleys and high mountain or mid as opposed to gently rolling, who i'm speaking with you the if the brains nerve cells fire off too many signal so that can trigger a kind of surge of electricity an epileptic seizure in the brain sometimes

a seizure can be a one time event, but epilepsy is the most common chronic neurological disorder affecting more than 50000000 people worldwide. ready scientists are looking for new ways to help. ready here at tubing and university hospitals, neurology clinic, olga last year. it's the intellect totally department. his goal is to help patients who own health much by coming treatments, all who have to take medication that cause a severe side effects. and kind of obviously trying a new medication can help. you should never give up on an epilepsy patient because every new medication represents a new opportunity to change their symptoms for the better. even if the patient has had seizures for many decades. and they're severe, which we on for the, for the good diagnostics are key for instance, imaging that patients brain ways within the g can provide important information.

here you can see this patient's brain waves. there's the normal background activity . but here there's a point that has the year marks of epilepsy, which is a typical peak and then slow share, which happens between seizures. and this is how we can identify whether someone has epilepsy or not. you have to then each diagnostics can also determine where in the brain the seizures originate. as doctors know that a medication isn't working well. they can sometimes even treat epilepsy with a surgical procedure. the surgery is an option for some focal epilepsy that originate in a clearly defined area of the brain. often seizures can be traced back to a clearly i into 5 of injury or normally in the brain. in the temporal lobe, for example. in an operation, surgeons can remove that, she's you causing the problem, but that's not without risk. depending on the area over the brain is being operated

on the risk essentially the difficulties with speech or memory. so decisions about surgery have to be made very carefully by an interdisciplinary medical team or glass. you often works together with new ologist. so good tools. yes. at 1st glance, the 2 hemispheres of the brain look the same. it's like you can see the structure is smaller and lighter on this side. that's almost certainly causing the seizure video from in our experience after surgery, up to 80 percent of patients stop having seizures is equal to shove on, zillow decided in favor of surgery. she's out of epilepsy since childhood. it was probably triggered by seizure caused by a fever. over the years, she's tried 6 different medications, including some of the new ones. but none of them really helped. even so, choosing to undergo brain surgery wasn't an easy decision. or in the heart of the

house in the end, hope one out as a chance that i might stop having seizures. it ended up being a good decision to 10 child. since the operations, 6 months ago shalom greta has been seizure free titles. she comes to the hospital for regular check ups to monitor the effects of the surgery. so how are you doing spin bed and my concentration is improved and i'm not having as many headaches, so things are going pretty well. fish. glad to hear it. we did an e g exam, so you can see here quite clearly. this is the left side where you have the surgery and everything looks normal. blue is the right, black is the left and both sides look exactly the same. a great results with no epileptic spikes, the end of this condition and then we tested your memory into the here were the results. these are the test as for how well you remember words. and there was no change compared to before the surgery. ok,

2 for the next one is maxed out. no mine. i had every day. life is a lot easier now ma'am. it's nice. it's more relaxed. joyful and i have a lot more hope these days. i'm not always waiting for the next seizure. i've already gotten used to not having them anymore. okay, now the hub, she'll continue to take her medication for a while in smaller doses and then gradually face it out. these days, new research results are leading to new treatment options for people with epilepsy . the team in tubing and the specialized motor called on channels that proteins that play a key role in epilepsy kinase or ion channels allow a cell to be electrically stimulated and they're located in the cell membrane. when inherited epilepsy is their altered, it's changing the electrical signal is able to, the cell becomes hyper ex idabel,

which can lead to epilepsy. and it seems to the researches in tubing and all studying genetic forms of epilepsy that involve defective on channels in the brain . they've been looking for medications that can increase or decrease dot general activity and found that a drug use the other new or logical conditions can help with this great and severe seizure disorder. that's on the open. we've been able to successfully treat children who seizures disappear, to them, showed improvements in their developmental disorder do. for example, some showed improvements and physical coordination or improvements to speed, which of course is a huge success for those families and so forth. how many again, the researches hoped that one day new therapies and even gene therapies will target these own channels in the cells even more effectively. whole with the goal of reducing or even preventing stages, and people with epilepsy. the width of lemon,

fragrant flowers, fresh roasted coffee. even though we only have about 350 all factory receptors, we can detect an amazing number of different sense. scientists found that certain odors can even improve memory and cognitive performance and sense could be even more powerful than you think. after getting up in the morning, one of the 1st things, a roman therapist, standard shanita, yon does, is switch on her diffuser. a few drops of citrus or orange oil are a great way to start today. most pieces of the booth is these oil molecules come through the nose undermine directly at the brains limbic system where they influence our emotional wellbeing. dog. let's do that. once the image sonata would defend the i'm flo, citrus oil like already know lemon and lined can really lift, you'll moved to stimulus opened. it's like

a bust of sunshine. the aroma therapist says natural sense couldn't even help alleviate pain about that as well. so refreshing and can lift her mood. floral fence such as rose, temperament, relaxation, tree, fragrances are said to have a calming effect. the general practitioners abena mon guide also uses naturopathic treatments and her practice. before treating patients with pharmaceuticals, she often tries aroma therapy 1st. the intention earnest and the essential oils contain fragrances that form and the leaves, fruits and roots of plums. from these frequencies a complex bio chemical mixtures that contain up to 500 different active ingredients in has these ingredients have responsible for the actual fragrance, but also account for its therapeutic effect. the simple cool essential oil can come

in capsule, liquids, or fragrances, are used topically and creams and oil. t tree oil is very popular. take them and both tea tree oil has not a septic effect, so it can reduce the viral bacterial or fungal load. the a variety of tea tree oil products which can be used topically, or consumed. generally speaking, essential oils are absorbed through their spirits, retract the skin deal factory system on the gastro intestinal tract, and then their effects unfold on the body. temperament can help relieve headaches and nausea. well camomile, fennel and caraway are thought to improve digestion. aroma therapy is like sandra shanita young. rely on natural compounds to treat a wide range of elements that st. louis flores, mine medicine cabinets at home is more or less empty dom is because i treat myself
