to bring use a story behind the news. we rolled about unbiased information for 3 months. the, it's quite a hard work are the most complex, oregon in your body of 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 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 me miles milestone. supplies them with nutrients and fluids. nobody suspects yet, but the piece will be short lived. deep inside the brain is just download this kind of really station for most sensory information. unimportant details gets swept under the table, but suddenly panic breaks out. the highly strong make de la head spotted some things that are folks, pun plants and emotions. and the hippo campus starts calling up bad memories. just in case the hypo solomon prepares the body to make a run for it by instructing the pituitary gland to pump chemical messengers into the blood stream. gradually the news spread throughout the entire neurological complex and is processed by

a wide range of different departments. the visual information is examined in detail options for averting danger or 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 movement signals are transmitted from

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

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 house 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 so called hypothalamus pituitary 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 you, what do you release as a lot of got this on your performance and concentration decrease? 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 tip, vigorous 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 and not the upside is that the physical activity

heads up your brains production of the feel good and you to transmit this order and often you notice a mode boost and simply feel better. and that's a great time to stop studying again when the body moves lots flu 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, our 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 help you focus better. it also helps you learn more any less time. it also improves our processing speed. so the,

the speed with which we're able to process that 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, if not stop without to choose a form of movement to actually night. it can be as simple as walking briskly, playing volleyball, or doing arabic set home any physical activity that increases your hot treat. mix

the defense, you'll experience an energy boost of to the single workouts available. if you manage to train $3.00 to $5.00 times for a week, the ethics will be even greater. so i'd say, 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 too hot competitive lead 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 hacks that can help you use 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 alert. 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 seems to be either sleep scientist. christina bloom is making her bed for the night. the

soft as this dance has tons ending. we spend about one 3rd of all life in this state of sleep and talk to me said, yeah, most of us don't know what happens when we're in the state for bog. and we have some spanish talking because it's a state of unconsciousness and things that type kind was fun, happen to the source to us. it's also crucial to somebody for if this is and is as much impulsive, life is wakeful, notice about fine. that's why i find sleep safe estimate touristy fast enough to in this box on in 2019 she began researching sleep at the university of basel as his doctor for he said, can i do love to sleep myself? and i usually sleep very well unless i have to work in the sleep thoughts with me. so what in the sleep lab, christina bloom at hendrick, colleagues, study people who suffer from sleep disorders. this involves measuring their brain activity while they're sleeping. the

live video just english because we might be on teach us, but that doesn't mean nothing is happening cuz he has quite the opposite. and there's lots going on in the brain and the whole day when we sleep as office funds . and here, for example, we know that metabolic products that will build up in the central napa system during the day a flushed out at night. so i've gone with those sorts of tenzing attachments, enough to outpatient image on the screen of the by this little guy. and even put says that it isn't often stuff and we know the telling you right. and the level you think tracers have the memories from during the day a transfer the long term memory types where they can be retrieved and used to come enough 1st. because as a learning aspect, that aspect to that, that's one reason why sleep is important to the state. 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 tight by lights, with taxes? do you like to also asked official liked, especially in these things. often, administration staff wants to test subjects. the researchers record their brain activity within each and identify and evaluate took their sweet stages. the large and slow waves depicted deep sleep phase, which is essential for restorative sleep. but which specific factors make sleep restorative? that's what christina promo wants to find out. loud but as best for you to manage, i'd say that so many people daylight especially them not to daylight outside as one of the most underestimated factors 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 if the house in our, in the morning is enough, or it's an hour is best sound design is a case of the more the better email or is there a point where the benefit plus tires fact ones hoping to can kind of get off for 5, actually we'll be able to give people some idea about how they can make the motion to stabilize the to improve. the sweetness has to be all, am i talking about some kind of stuff to focus on in child support? austria, christina bloom 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 give us a tattoo and thank 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 rest guide from the daily grind. this is features as like, logically it gives you some distance from day to day line and find that on something else and they constantly on and on them you need to concentrate on the

partisans, especially when it's narrow and winding, where you have to climb product. if you're calling some types of requests and lots of concentrations, so you don't even have the mental space to think about everyday thing on stuff, isn't there not an important aspect of relaxing and being physically active? it's important to me to see when we have all kinds of ways to get stick on cost solution tab on the needs to be as adult. come to charles, it's when day and night who the builder who sounds like the valleys and high mountain mit as opposed to gently rolling headlines. hmm. the if the brains nerve cells fire off too many signal 2nd 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 clinics, olga last year. it's the phillip tells you department his goal is to help patients who own health much by common 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 you, every new medication represents a new opportunity to change their symptoms for the veterans. even if the patient has had seizures for many decades. and they're severe once we on for the, for the good diagnostics. ok, key for instance, imaging that patients brain ways within the g can provide important information.

here you can see this patient's brain ways. 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 shift, which happens between seizures. and this is how we can identify whether someone has epilepsy or not. you have to at least 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 and exceed the defined area of the brain. often seizures can be traced back to a clearly identifiable injury or normally in the brain. in the temporal lobe, for example, in an operation searches can remove the tissue causing the problem. but that's not without risk. depending on the area over the brain is being operated on. the risk

seems to difficulties with speech or memory. so decisions about surgery have to be made very carefully by an interdisciplinary medical team, whole glass. you also 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 confusion from. in our experience after surgery, up to 80 percent of patients stop having seizures. shoveling regular 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. in the heart of the

house, in the end, hope one out of the 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. she comes to the hospital for regular checkups to monitor the effects of the surgery. so how are you doing in best 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 and 100 by the end of this condition. and then we tested your memory into the here the results. and these are the taxes for how well you remember words. and there was no change compared to before the surgery. ok to for the next

one. is max out know mine eyes 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. now she'll continue to take her medication for a while in smaller doses. and then gradually phase it out. these days, new research results are leading to new treatment options for people with epilepsy . the team in tubing and specialized in water cold on channels that proteins that play a key role in epilepsy canal is all ion channels allow a cell to be electrically stimulated and they're located in the cell membrane. when inherited epilepsy is there alter, it's changing the electrical signal is able to, the cell becomes hyper ex, idaho,

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 channel 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 to, for example, some showed improvements and physical coordination or improvements to speed. which of course is a huge success for those families. if it is, how many, again, the research has 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 linen,

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 have 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 aroma therapy standards shanita yon does is switch on her diffuser. a few drops of citrus or orange oil are a great way to start the day. must do so, so the booth is these oil molecules passing through the nose, undermine directly at the brains limbic system where they influence our emotional wellbeing. dog. let's do that once it would. so now this would defend the i'm flo citrus oil like you already know, lemon and lined can really lift you moved. tail stimulus opened. it's like

a bust of sunshine. the aroma therapist says natural sense can even help alleviate pain. both sitter throughout the refreshing and can lift her mood. floral fence such as rows can promote relaxation tree. fragrances are side 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 detail spa essential oils contain fragrances that form in the leaves, fruits and roots of plums from these fragrances, a complex bio chemical mixtures that contain up to 500 different active ingredients . beaten has these ingredients are responsible for the actual fragrance, but also account for its therapeutic effect. the simple essential oil can come

and capsules, liquids, or fragrances are used topically, and cranes and oil. peach. tree oil is very popular. tip um and both tea tree oil has an antiseptic effect so it can reduce the viral bacterial or fungal load. the variety of tea tree oil products which can be used typically all consumed. generally speaking, essentially, oils are absorbed through their spirits, retract the skin, the all factory system and 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 to tow, missed more or less. m t. call me because i treat myself mostly with the central
