like sports farms and destroy slides. what is the legacy of this wide spread race as depression today? history. we need to talk about here, the stories, shadows of german colonialism. 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. the nobody suspects yet, but the piece will be short lived. deep inside the brain is to sell them this kind of relay station for most sensory information. unimportant details gets swept onto the table. but suddenly panic breaks out. the highly strong a. make de la had spotted something that of oaks pod plans 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. as 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 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 who's 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 turned to shine. it's where complex sequences of movements are trained and precisely coordinated with the help of a pincer grip. the spider is grabbed by a leg and transported into the card. the 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 keep 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 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 help alleviate 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 decrease, this is where exercise comes in handy. it reduces the cortisol levels of 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. another upside is that the physical activity heads up, your brains production of the feel good, and you to transmit this on and off. and you'll notice a mod boost and simply feed 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 in less time. it also improves our processing speed. so the, 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 managed 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 too hard to competitive lead during exam periods. working out shouldn't create additional performance pressure that will help you find the perfect 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 of his. that's whose tons ending we spend about one 3rd of all life in the state of sleep and talked to him and said that most of us don't know what happens when we're in the state. football, give me some information to gain because it's a state of unconsciousness and things that type kind was fine happen. and then all of a sudden switched out. it's also crucial because of only focus is on, does as much impulse of life is wakeful. notice about fine, that's why i find sleep sofa may 20 fast enough to into stops of 2019. she began researching sleep at the university of basel. uh there's not that 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. so what in the sleep lab, christina bloom at hand or colleagues study people who suffer from sleep disorders . this involves measuring their brain activity while they're sleeping,

the live, you know, just even if we might be on teach us. but that doesn't mean nothing is happening cuz he doesn't get in quite the opposite. and there's lots going on in the brain in the body when we sleep, the smell office bonds. and here, for example, we know that metabolic products that we build up in the central napa system during the day a flushed out at night. so how can i know that those sorts of guns in a town is enough? obviously some damage on the screen by this one was hired even put says that it is an office of and we know the telling you right in 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 email 1st because as a learning aspect, that aspect to the ad. 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 persons changing one variable each time the

positive project. ignoring basel with, are you interested in the role type by lights with tax that you like to also was official liked, especially in the evenings, often administration staff wants to test subjects, the researchers record their brain activity within each and identify and evaluate their sweet stages. the large and slow waves depicted deep sleep phase, which is a central for restorative sleep. but which specific factors make sleep restorative? that's what christina promo wants to find out. now that as best for you to manage, i'd say that for many people that you like, especially them not true daylight outside i is one of the most underestimated foxes when it comes to a good night, sleep 5 months up to me. so we want to know how much day like you need for it to

have a significant positive effect on sleeve a sick day. and then this month i'll finish off the hot as well. so now we don't know the cost in our, in the morning is enough, or as an hour is better than design is a case of the more the best email or is there a point where the benefit plus tires affect one's hoping to can kind of get off the supply thankfully will be able to give people somebody to about how they can make the motion to stabilize the to improve. the slickness has to be all, am i talking about some kind of stuff to focus on inside of support? austria. christina bloomer 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. uh, let me get this attached to you and ask you. so the king raises my energy levels and helps me real on kind of one is to. so i think that's because it's rustic, like from the daily grind to seizures,

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 farther, but 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 aspects of your life? because and that's where they can being physically active. it's important to me to see when we have all kinds of ways to get stick on prostitution, tabs on the desk that needs to be as an adult, calm and charles between day and night. hopefully bigger will sound like the valleys and high mountain mit, as opposed to junky rolling. who wants to meet with you? the if the brains nerve cells fire off too many signals 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. scientists are looking for new ways to help. ready very tubing and university hospitals, neurology clinics on the last year. it's the policy 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 what needs to be 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 better. even if the patient has had seizures for many decades. and they're severe once we on for the good

diagnostics. ok key, for instance, imaging a patients brain ways within the g can provide important information. here you can see this patient's brain ways, stairs than normal background activities. but here there is a point that has the year marks of epilepsy which is a typical peak. and then slow shift, which happens between seizure, 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, that can sometimes even treat epilepsy with a surgical procedure. the surgery is an option for some focal epilepsy is that originate and it clearly defined area of the brain. often seizes can be traced back to a clearly identifiable injury or normally in the brain in the temporal lobe. for example, in an operation surgeons 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 simply difficulties with spatial memory. so decisions about surgery have to be made very carefully by an interdisciplinary medical team, whole glass you often works together with new ologist. so good tools. yes, at 1st glance, the 2 hemispheres of the brain look the same site. you can see the structure is smaller and lighter on the side. that's almost certainly causing the seizure, clumsy so from in our experience after surgery, up to 80 percent of patients stop having seizures, shoveling viola decided in favor of surgery. she's had 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. i am in the heart of 2 holes 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 operation, 6 months ago shalom greta has been seizure free. she comes to the hospital for regular checkouts 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, the end of this condition and then we tested your memory into the here were 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 and motor cold on channels that proteins that play a key role in epilepsy. ukuleles alden, ion channels allow a cell to be electrically stimulating 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, 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 general activity and found that a drug use the other new or logical conditions can help with this great and severe seizure disorder. that somebody else can. we've been able to successfully treat children who with 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. how many again, the researches hope 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 come through. the nose undermine directly at the brains. limbic system where they influence our emotional wellbeing, dog. let's direct off. once the image, so now this would defend the i'm flo citrus oil. it's 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 can 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 in the book store 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 capsule liquids or fragrances or used topically and cranes and oil. peach. tree oil is very popular to them. and both tea tree oil has an antiseptic effect, and it can reduce the viral bacterial or fungal load. the variety of tea tree oil products which can be used typically, or consumed normally. 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. it's like sandra shanita yan, rely on natural compounds to treat a wide range of elements that st. louis flores,
