Oksitocin je hormon koji se oslobadja kod trudnica za izazivanje porodjaja, kod dojilja za indukovanje laktacije, i (izgleda, meni kao laiku) to je primarna funkcija ovog hormona kod sisara. Takodje, kao sto je i objavljeno ranije:

Oxytocin increases trust in humans

Michael Kosfeld1,5, Markus Heinrichs2,5, Paul J. Zak3, Urs Fischbacher1 and Ernst Fehr1,4


Trust pervades human societies1, 2. Trust is indispensable in friendship, love, families and organizations, and plays a key role in economic exchange and politics3. In the absence of trust among trading partners, market transactions break down. In the absence of trust in a country's institutions and leaders, political legitimacy breaks down. Much recent evidence indicates that trust contributes to economic, political and social success4, 5. Little is known, however, about the biological basis of trust among humans. Here we show that intranasal administration of oxytocin, a neuropeptide that plays a key role in social attachment and affiliation in non-human mammals6, 7, 8, causes a substantial increase in trust among humans, thereby greatly increasing the benefits from social interactions. We also show that the effect of oxytocin on trust is not due to a general increase in the readiness to bear risks. On the contrary, oxytocin specifically affects an individual's willingness to accept social risks arising through interpersonal interactions. These results concur with animal research suggesting an essential role for oxytocin as a biological basis of prosocial approach behaviour.

E, sad -

kako se vama cini mogucnost slobodne prodaje ovog hormona, pri tome i relativno lako dostupnog (godisnja zaliha vredi trenutno samo 180$)?

Jos nema ispovesti zadovoljnih kupaca koji su i politicari, ali ima onih koji su dobili sjajan posao, zaproseni su ili u slucaju barmena, koji prijavljuje cak pet puta vece nepojnice sa Liquid Trust-om no bez. Upotreba ili zloupotreba?

"... the original Swiss researchers doubt that it could easily be used to influence people because it takes an hour to have any effect. But we beg to differ. Like many hormones, oxytocin has an array of effects: it encourages animals to interact, cements pair-bonds, figures in orgasm, triggers labour and starts a mother's milk flowing. The nasal spray the Swiss used for their research has been marketed for years as a nursing aid. According to a colleague of ours who used it for this purpose, it works in seconds. It is given to nursing mothers as a nasal spray precisely because when administered in this way the hormone crosses straight into the brain, triggering the lactation reflex. Our colleague has no doubt that a sniff of the stuff, even when it's applied externally, as with Liquid Trust, might well have an instant and powerful effect. But what effect, apart from making milk flow?

The Swiss say that oxytocin causes people to be trusting by lowering barriers to social interaction. So perhaps people who have taken it feel more at ease approaching strangers. ...This is rather different from the ability to manipulate people. ..." (NS, Feedback)

Dobro, nema komentara, jasno mi je al' bi mogao onda bar jedan raport kako radi, ko je odmah narucio vec bi trebalo da je stigla posiljka...

Nema dovoljno podataka, potreban nam je eksperiment. Predlažem tebe za dobrovoljca. Treba da ideš po ulicama, kafićima i železničkim stanicama, i da nepoznatim ljudima kažeš: "Primetila sam te od ranije. Vrlo si zgodan. Hoćeš li da pođeš u krevet sa mnom?". Prvo 1000 puta bez hemikalije, a onda 1000 puta kad se prsneš oksitocinom. Ono što merimo je koliko puta možeš da nateraš sebe da to uradiš

Hm, S.
Ti bas resila da se zabavljas.

Ja tesko da sam strucnjak za oksitocin & njegova dejstva, ali znam da je spektar njegovog potencijalnog delovanja veoma sirok. Takodje, ono sto sigurno znam je da ga ima i u timusu i to u znacajnoj koncentraciji sto, naravno, samo potvrdjuje tezu da neuroendokrini i imuni sistem rade mnogo vise zajedno na ranoj diferencijaciji T-limfocita, nego sto se to cini na prvi pogled.

Kako ce oksitocin uticati na povecanje poverenja medju ljudima, ja pojma nemam, ali koliko vidim postoje studije i studije o tome (sad sam malo "procackala" po Medline-u). OK, treba dobiti sve te grantove..heh. Nadjoh i da je neko ustanovio da dejstvo oksitocina zavisi od "prethodnog socijalnog statusa" posmatrane experimentalne zivotinje, po principu: dominantni majmuni su postali jos agresivniji, a kod povucenih je nesto i delovalo (...Dominant males responded to OT administration with increased sexual and aggressive behavior, whereas subordinate males displayed more associative behaviors. The differential behaviors might be due to the higher serum testosterone levels in dominant animals...). Tu sad treba uzeti u jednacinu i veliki broj ostalih hormona, peptida...koji mogu da uticu na sve to.

Nisam pametna.
A ponekad me malo i Nature nervira svojim clancima.
Posebno kad vodja tima koji je objavio ovaj rad ima doktorat in Economics.
Bice da imam predrasude.
Mislim, ne zelim da iskljucim postojanje blagotvornog efekta oksitocina (ipak sam se porodila 2x..haha), ali nisam sigurna na kom je nivou sve to danas.
A posebno me nervira senzacionalisticki naslov clanka!!!!
Mislim, "trust" i "humans" u istoj recenici????

Tnx, mnogo - kako meni nije uza struka, nisam znala ni gde a vala ni sta bih trazila, sad bar znam da ima jos istrazivanja na temu. Da, i ja spadam u one kojima Nature sve vise ide na ganglije, i jasno mi je da kad god ima cross-over-a izmedju naucnih disciplina mnoge stvari koje prodju ne bi imale nikakvu sansu u "maticnom" najboljem casopisu. Sto ima i dobrih, ali i losih strana, a koje preovladjuju izgleda da zavisi od slucaja do slucaja.

Cini mi se da recimo sa obrazovanjem iz ekonomije lakse objavis rad koje je u osnovi bioloski (uz odgovarajuci tim razume se), no sto bi bilo da npr. jedan biolog objavi rad iz ekonomije. Koliko je to do uredjivacke politike, ne umem da procenim. A i ne znam da li "drustvenjaci" imaju casopis profila kakav su Nature i Science, mozda je to Economist, ali mi bas i ne lici. Ali definitivno takvi radovi dobijaju najvise publiciteta, pretpostavljam da su pisani najjednostavnijim jezikom i izgledaju potpuno jasni i nepobitni, istiniti.

@mac, ahem... taj hormon zene imaju dovoljno, oni koji ga kupuju i kojima treba su - muskarci - bar prema reklami na onom sajtu
