Cudite e Trurit

-30% e 80 vjecareve mund te mesojne pothuaj njesoj si te rinjte

-Truri megjithse eshte sa 2% e peshes se trupit, perdor 20% te energjise se tij

-Kjo energji do te ishte e mjaftueshme qe te ndriconte nje llambe 25Watt

-Ne nje dite, truri gjeneron me shume impulse se te gjithe telefonat qe ka bota

-Truri mund te kryeje rreth 70 000 mendime ne dite.

-Pas moshes 30 vjecare truri reduktohet ne 0.25% te mases se vet. KJo nuk do te thote qe ul aftesite funksionale.

Truri i Albert Einstein peshonte1,230 grams pra mjaft me pak se mesatarja e trurit human, 1300 deri 1400 gr

Po shikoja 1 nate 1 emision per trurin ... vertet shume kompleks e mistik ne te njejten kohe ....

Pyetja qe me lind eshte si ka mundesi qe truri i njeriut eshte kaq i veshtire per tu kuptuar?!!! e te mendosh qe 500 milion vite evolucion e akoma sdime gje per te ....

na trego ndonje kuriozitet me shume per trurin jam e interesuar

Truri nuk ka cudi, duhet thjesht kuptuar si funksionon avash avash.

Studjohet nga shume fakultete dhe disiplina. Por meqe eshte fjala per inxhinieri, nje nga projektet me te medha eshte Blue Brain Projekt. Ai mundohet te analizoje vetem 1 mm2 tru ne çdo aspekt deri ne detaje molekulare. Aftesia llogaritese e nevojshme kerkon superkompjutera qe rralle gjehen ne bote. Disa universitete nga vende te ndryshme te botes marrin pjese ne projekt:

Magjepsiet dhe mahnitjet e trurit...

Me terheqin artikujt reth kerkimeve ekperimentale ndaj studimeve te trurit vetem qe s'i kam qef baboon dhe minjte dhe laboratoret se do i futesha vete kesaj rruge.... mbase ndryshoj mendje me vone. Truri s'meret vesh se ne ca rrugica, autostrada e qoshka na magnitizon

Une ndjek The Brain Observatory. Diku ne nje teme kam sjell nje video per proceduren ndaj coptimit te trurit te Henry Molaison i cili kishte amnezi shkaktuar nga nje operacion ne tru diku ne 1950. Ai i dhuroi trurin pas vdekies shkencetareve te ketij grupi te cilet jane te interesuar si dhe ku krijohen kujtesat. Vetem disa muaj me pare u pustua procedura live s'po e gjej dot:

Ja nje dokumentar interesant:

Vertet.



Sigurisht qe trurit i vishen te gjitha funksionet e ndergjegjshme dhe te pandergjegjshme te aktivitetit njerezor. Eshte shume intriguese.

Para ca kohesh, ndoshta nje ose dy vjet, u zbulua (pjeserisht) mekanizmi i transmetimit te informacionit.

Dihet qe per te transmetuar nje informacion brenda trurit, nga nje zont tek tjetra duhet kaluar nepermjet sinapseve te neuroneve. Shpejtesia me te cilen kalojne keto informacione, nuk shpjegohej me rruhen normale fiziologjike te tille si: qelize-sinaps-qelize. Kjo do ta ngadalesonte shume kohen e transmetimit. Kjo i shtyu shkencetaret qe te ndjekin rruge te tjera te terthorta.

KJo pra solli nje zbulim vertet fantastik. Truri perdot ATP-ne per te transmetuar impulset. Pra molekula energjitike u perdorka per te percjelle nje mesazh. Gjate cdo mesazhi qe ajo perciell, harxhon nje "fosfat" dhe kthehet ne ADP

ja kshu:

Adenozintriphosphati - (mendim + njephosphat) = Adenozindyfosphat

Kjo eshte edhe arsyeja qe truri harxhon aq shume energji, rreth 100 here me shume se muskuli

Nuk e perktheva kete artikull se mendova qe do ja prishja lezetin, pastaj...duke e lexuar vura re ca gjera qe jane si kshu tur dhe mami me ka thene qe te mos lexoj te tilla.

A Sex Chip? Targeting the Brain's Pleasure Center with Electrodes
Could growing clinical use of brain electrodes lead to a chip for sexual stimulation?

By Gary Stix

A fundamental goal of neuroscience has always been to deduce the brain systems that underlie such basic drives as hunger, thirst and sex. In 1956 the well-known physiologist James Olds wrote an article for Scientific American, called “Pleasure Centers in the Brain,” that described how a rat kept without food for a day was lured down a platform by a tasty meal. En route to dinner, it received a pleasurable electric shock. The rat never showed up for mealtime, instead choosing to delight in the arousal. With the optimism characteristic of that era, Olds concluded that stimulation experiments would lead to an understanding of neural functioning that would allow “one drug that will raise or lower thresholds in the hunger system, another for the sex-drive system, and so forth.”

Fifty years later the promise of Olds’s vision has yet to fully materialize. Better drugs are needed to suppress appetite and spark sexual desire. But fascination has grown in recent years with taking Olds’s more direct route of stimulating the central nervous system.

So far no one has created anything like the Orgasmatron, first seen in Woody Allen’s 1973 comedy Sleeper. Undaunted, one clinician—who has trademarked the name Orgasmatron—ran a small, FDA-reviewed pilot trial to test the possibility of applying electric current to the spine to reverse sexual dysfunction. Stuart Meloy, a North Carolina physician who specializes in implanting spinal electrodes to alleviate pain, found by chance that a slightly off-kilter placement in the lower spine caused one woman to exclaim: “You’re going to have to teach my husband to do that.”
In 2006 Meloy reported that 10 of 11 women who stopped having or never had orgasms experienced sexual arousal with the temporary implant and, of that group, four had their ability to experience orgasm restored. Meloy is seeking a medical device manufacturer to bring the costs down to $12,000 for a permanent implant, about the charge for breast enlargement.

Neural electrodes may eventually move up the spinal cord to what is often characterized as the body’s primary erogenous zone. Deep-brain stimulation, the placing of electrodes at strategic spots far underneath the skull, now treats a variety of ailments, including Parkinson’s disease and dystonia (uncontrollable twisting of a body part caused by involuntary muscle contractions). An occasional side effect is spontaneous sexual stimulation.

Tipu Aziz, a neurosurgeon at the University of Oxford, speculates that better knowledge of the brain’s pleasure centers—combined with improved surgical procedures and control of electrical pulses—may make a sex chip in the brain a reality. “Lack of sexual pleasure is a huge loss in one’s life, and if one could restore that, that would enhance someone’s quality of life enormously,” Aziz remarks.

Some neuroscientists are not so sure. Morten L. Kringelbach, a researcher at Oxford who sometimes collaborates with Aziz and wrote the book The Pleasure Center (Oxford University Press, 2008), cautions that hedonic experience may consist of an impulse corresponding to “wanting” and another that represents “liking.” To succeed as a therapy, a sex chip would have to address the challenge of switching on neural circuits that activate both impulses. In a 2008 paper in Psycho¬phar¬ma¬col¬ogy with University of Michigan at Ann Arbor psychologist Kent Berridge, Kringelbach illustrated the distinction between the two by citing an infamous case from the 1960s, in which psychiatrist Robert Heath placed “pleasure electrodes” in the brain of a gay man code-named B-19, in part, as an attempt to “cure” his homosexuality.

The patient pressed a button compulsively to turn on an electrode that induced a desire for sex, but whether he actually enjoyed the sensation was unclear. The stimulation alone did not induce orgasm, and B-19 never expressed any real contentment while hitting the button. Kringelbach warns against similar misuses of contemporary deep-brain stimulation. “It’s important that we not get carried away by this technology,” he says. “It’s important that we not end up in another era of psychosurgeries,” referring to the mid-20th century popularity of lobotomies to treat psychiatric disorders.

In the end, a sex chip may serve as a prop for moviemakers, but turning on the current may never become a truly practical means of adding the buzz back in your love life.

Ja kshu, Faje na fal per prishjen e rregullit

Une ne fakt kam nje mendim tjeter.
Psh te prodhohet nje cip qe t'ja vene ketij Tigerit qe luan golf se nuk paska lene femer me kembe. Oj. Kerkon Petteri, po ku te lene keta, pa le priftrinjve si ju shkon ai cipi, biringji.

ATP nuk transmeton gje, eshte molekule energjie

Ja kshu e ja ashu, po me mire te vihet linku sesa copy paste anglisht. Ja kshu... sa te shikojne 1 meter faqe anglisht s'e lexon me njeri temen... ja kshu

Ndersa per ATP e ADP, ka ndonje link? Prape po keqinformohet publiku. Truri perdor neurotrasmetitore per komunikim, dhe harxhon energji per te derguar neurotrasmetitoret. Shpejtesia e transmetimit ne fijen nervore eshte fizike e thjeshte (mjafton te behen dy llogari qe te dale). Nese shkencetaret i habit shpejtesia e leshimit te neurotrasmetitorit ne fund te fijes nervore kjo eshte pune tjeter. Sidoqofte ATP e ADP nuk jane neurotrasmetitore. Neurotrasmetitoret kryesore jane glukosa, GABA, acetlikolina, dopamina, serotonina, norepinefrina. ADP dhe ATP jane molekula energjitike qe perdoren shume brenda qelizes, si dhe ne fosforilimin e receptoreve qe hapin kanalet e qelizes tjeter nervore ku bie. Ne qelizen qe transmeton sinjalin ATP eshte pjese e procesit qe hap qeset me neurotrasmetitor (synaptic vescicles, duken ne figuren lart), por jo neurotrasmetitor.

Megjithate aresyeja pse truri harxhon shume energji eshte kurioze. S'me kish shkuar mendja te pyesja veten perpara.

Sexi ne tru...

Vepron ne te njejtat zona ku veprojne dhe drogat. U vu re fillimisht tek minjte, qe kur vendos nje elektrode ne Septum Pellucidum (diku ne mes te trurit) miu shtyp gjithe kohen butonin stimulues. Madje nuk hante me, nuk pinte, nuk kishte interesa te tjera, donte vetem te shtypte butonin qe eksitonte ate zone te trurit.

Ngaqe seksi aktivizon te njejten zone si drogat lind pyetja:
"A krijon seksi dipendence si drogat?"

Pyetje qe ben per te qeshur nje salle me 300 studente, por mbetet per t'u hetuar.

Paska goxha info te utube- i

Angjel si te kam motra?

Shume e bukur ajo qe solle. Ku e gjete me. ne Nevetube?

Nuk te hyj ne fushe Cedrus jo. Nga jashte po te flas. Po thashe nga na doli ATP neurotrasmetitori kryesor ne tru... Artikulli eshte permbledhje qe flet per rolin modulator qe njihet si i tille prej dekadash (jo kohet e fundit). Por nuk kuptohet nese mund te jete molekula kryesore e transmetimit, edhe pse eshte interesante qe ka aftesi modulatore. Megjithate eshte kurioze qe ka efekt neurotransmetues, qofte dhe dytesor. Se kisha vene re.

ATP modulates communication among neurons and between neurons and support cells called glia. Signaling by ATP and its breakdown product adenosine is involved in sleep, memory, learning, movement and other brain activities, and excessive signaling may be involved in epilepsy and some psychological disorders. ATP also stimulates tissue development and repair following injury but may promote cell death in neurodegenerative diseases.
