@erjedna teba sa to netýka ty bezmozog ,zostan v klude....pozrel by som si,jak sa ty naučíš 200 slovíčok za den,ked máš problém a naučit jednu súvislú vetu vyslovit 8)
Ja to tak nenávidím, keď niekto porovnáva výkon počítačov a mozgu. A to s tými dvesto slovíčkami je tiež podmienené jednotlivcom a jazykom najskôr plus na uloženie do trvalej pamäti ....
The human brain is the most complex and least understood part of the human anatomy. There may be a lot we don’t know, but here are a few interesting facts that we’ve got covered.
Nerve impulses to and from the brain travel as fast as 170 miles per hour. Ever wonder how you can react so fast to things around you or why that stubbed toe hurts right away? It’s due to the super-speedy movement of nerve impulses from your brain to the rest of your body and vice versa, bringing reactions at the speed of a high powered luxury sports car.
The brain operates on the same amount of power as 10-watt light bulb. The cartoon image of a light bulb over your head when a great thought occurs isn’t too far off the mark. Your brain generates as much energy as a small light bulb even when you’re sleeping.
The human brain cell can hold 5 times as much information as the Encyclopedia Britannica. Or any other encyclopedia for that matter. Scientists have yet to settle on a definitive amount, but the storage capacity of the brain in electronic terms is thought to be between 3 or even 1,000 terabytes. The National Archives of Britain, containing over 900 years of history, only takes up 70 terabytes, making your brain’s memory power pretty darn impressive.
Your brain uses 20% of the oxygen that enters your bloodstream. The brain only makes up about 2% of our body mass, yet consumes more oxygen than any other organ in the body, making it extremely susceptible to damage related to oxygen deprivation. So breathe deep to keep your brain happy and swimming in oxygenated cells.
The brain is much more active at night than during the day. Logically, you would think that all the moving around, complicated calculations and tasks and general interaction we do on a daily basis during our working hours would take a lot more brain power than, say, lying in bed. Turns out, the opposite is true. When you turn off your brain turns on. Scientists don’t yet know why this is but you can thank the hard work of your brain while you sleep for all those pleasant dreams.
Scientists say the higher your I.Q. the more you dream. While this may be true, don’t take it as a sign you’re mentally lacking if you can’t recall your dreams. Most of us don’t remember many of our dreams and the average length of most dreams is only 2-3 seconds–barely long enough to register.
Neurons continue to grow throughout human life. For years scientists and doctors thought that brain and neural tissue couldn’t grow or regenerate. While it doesn’t act in the same manner as tissues in many other parts of the body, neurons can and do grow throughout your life, adding a whole new dimension to the study of the brain and the illnesses that affect it.
Information travels at different speeds within different types of neurons. Not all neurons are the same. There are a few different types within the body and transmission along these different kinds can be as slow as 0.5 meters/sec or as fast as 120 meters/sec.
The brain itself cannot feel pain. While the brain might be the pain center when you cut your finger or burn yourself, the brain itself does not have pain receptors and cannot feel pain. That doesn’t mean your head can’t hurt. The brain is surrounded by loads of tissues, nerves and blood vessels that are plenty receptive to pain and can give you a pounding headache.
80% of the brain is water. Your brain isn’t the firm, gray mass you’ve seen on TV. Living brain tissue is a squishy, pink and jelly-like organ thanks to the loads of blood and high water content of the tissue. So the next time you’re feeling dehydrated get a drink to keep your brain hydrated.
1. blbosť, jedna mozgová bunka sama osebe dosť dobre kapacitu nemá, lebo mozog ukladá informácie nie do neurónov, ale do synapsí (spojení medzi neurónmi). čiže jedna mozgová bunka sama osebe má v podstate kapacitu nulovú. dve mozgové bunky majú kapacitu jedného bitu (môžu byť prepojené alebo nie). tri mozgové bunky majú kapacitu 5 bitov, ak správne počítam (5 rôznych variánt prepojenia), atď...
4. toto ti protirečí s prvým bodom, ale to nevadí, lebo ten je aj tak blbosť.
5. nie, mozog nepracuje viac v noci. len pracuje iným spôsobom a na iných veciach. a chcel si povedať "počas spánku", to nie je to isté ako "v noci"
6. áno, toto som vedel odkedy som videl scénu v mlčaní jahniat kde hannibal niekomu kto je pri vedomí odreže kus mozgu, osmaží ho, a dá ho dotyčnému zjesť.
7. ako ktorý. viď ľudí na internete pre dostatok príkladov že niektoré mozgy nezvládnu ani jedno.
8. totálna blbosť, mozog je práve jediný orgán ktorý sa po dokončení svojho vývoja už neregeneruje, nové bunky netvorí. ale tvorí nové synapsy (spojenia medzi neurónmi), pretože to je spôsob ktorým sa učí a ukladá informácie
9. toto sa zvykne používať opačne, že "preto bolesť/dotyk cítime asi s 15milisekundovým oneskorením"
odporúčam nabudúce keď budeš chcieť niečo takéto napísať, tak si najprv nájsť nejaký normálny zdroj s korektnými informáciami
tak to ze sa zvladne mozog naucit 200 slovicok denne je strasna blbost podla mna akoze kazdy je iny u niekoho mozno ano ale to je vlastne aj to preco je toto vsetko blbost lebo kazdy ma iny mozog podla mna
Roleta je špeciálny inkognito mód, ktorým skryješ obsah obrazovky pred samým sebou, alebo inou osobou v tvojej izbe (napr. mama). Roletu odroluješ tak, že na ňu klikneš.

"neurons grow" je veľmi nejednoznačný pojem...
@leftbehind
...hmm... si predstavím koľko mi ich tak asi vzniká za bežný pracovný deň, a... neviem si predstaviť. príliš veľa.
