Turn off your mind, you and swimming relax downstream, in fact. A new scientific study suggests that Psilocybin--the psychedelic drug found in magic mushrooms - "not activated" parts of the brain but rather tied restricts blood flow and connections between the regions of the brain on perception and cognition. Imperial College London psychopharmacology researchers Robin Carhart-Harris was the results of this study, in which 30 volunteers were injected with psilocybin and underwent Convention Conference on psychedelic brain scans, on last week of breaking awareness. Interestingly, that helps support the data psilocybin of potential use for the treatment of depression. From New Scientist:
less blood flow was the areas of the brain known as the medial prefrontal cortex, thalamus and cingulate posterior. "To see a decrease was surprising." We thought that experience equalled more activity, but this formula is clearly too simple, "says Carhart-Harris.""We saw an increase in all regions," he says."Psychedelic drug cuts brain blood flow and connections" (thanks, Jody Radzik!)Prefrontal cortex also observed, such as between the hippocampus and posterior cingulate and media have been reduction in connectivity.
"Under psilocybin, you see a relative decline in the"talk"between the hippocampus and these cortical hub regions," says Carhart-Harris. "Changes in function in the posterior cingulate are associated with particular changes in the consciousness."
Psilocybin has been a similar chemical structure of serotonin - mood regulating a hormone - and therefore binds to serotonin receptors in neurons in the brain. The drug can have therapeutic potential, because the nerves of the serotonin system is also a destination for existing antidepressants.
