The penis he will own?

Everything, everything, you know all about the "willy", not because the singer Pierre Perret, but through the work of Dr. Irwin Goldstein of Boston University. And, yes, the intimate mechanisms of erection no longer have secrets for biologists.

Relaxation or relief, if the male sexual organ sometimes hesitant in his movements, that it is subject to contradictory influences of the higher authority that is our brain. The study group American impotence and Dr. Irwin Goldstein did not hesitate to analyze in detail these interactions. Thanks to the curiosity of the biologists, * we now know more about one of the key events of life after puberty.

When master brain inhibits our sexuality
A pretty woman in sight, evocations naughty, a voluptuous scent recalling memories of the phallus and ask nothing better than riding in the front line under the influence of excitatory neural circuits. Yes, but. Because of conflicting orders from others, too, said upper hemisphere and transmitted via the spinal cord and nerves, tend to oppose this. And the penis is low profile.

Thus, the overall trend is to inhibition. Thus, modern man would probably have to replicate the bonobo apes to unbridled sexuality. The fault attributed to a core, said paragigantocellulaire located within our poor heads. The work of this castrating aims to prevent erections. No wonder, then, if the desire is sometimes so fleeting and male sexuality is often sensitive to stress, anxiety ... But it is true that life does have its ups and downs!

Who sleeps ...
But nothing like the night, at least when asleep! Certainly, during phases of slow wave sleep, the negative control of brain remains and the penis remains to turn ... dormant.

However, when REM sleep appears that in which we dream, the vigilance of brain areas is relaxed and the phallus, which was only waiting for this, was back in action. This explains why every male among normally formed, he sleeps or not solo, four to five erections occur every night.

A method of exploring a bit primitive impotence, but that has proven, however, is also to stick a stamp night at the fatal spot. Nothing could be more reassuring if he becomes an awakening!

No need to have the head
There is also packed erections. Caress and exciting vision, penis then takes it up without informing the cortex. In this case, the neural circuitry involves a small region of the spinal cord, which transmits the order to remedy erectile nerve when it was put in appetite with pleasant sensory messages.

Advantage of this alternative approach: it allows men to have a quadriplegic erection. Useful to know the joys of fatherhood, but not always ideal to appreciate those of sexuality since the sensations are among those with disabilities, unfortunately, very blunt.

The erection: a unisex phenomenon
Namely, finally, the erection is not unique to the male and the neural circuits involved are more or less the same for sex supposed low. Equivalent in all parts of the penis, although smaller, the clitoris is, in fact, too sensitive to the overall inhibitory effects of the brain and those stimulants love. Venus in the footsteps of Priapus, the god Latin symbolizing virility. Who would have thought?
