The research team found that LSD reduced connections between regions of the brain that govern cognitive processes while simultaneously increasing connectivity in brain networks associated with sensory functions.The drug does this by stimulating a particular receptor in the brain for the neurotransmitter serotonin, the 5HT2A receptor, known to be implicated in mood regulation and cognition.Tags: Bristol University History Of Art DissertationThesis For The Merchant Of VeniceLeadership Essays ExamplesMedical Clinic Business PlanShort Term Business Plan ExampleDefinition Of The Word Deserted
The researchers aimed to replicate the results for the higher dose of estradiol using the same study design but in a different country and "without any commercial involvement," which, Weiser said, "is extremely rare." The study included 200 premenopausal women (mean age, 38 years) who lived in the Republic of Moldova, had schizophrenia or schizoaffective disorder, and were receiving antipsychotic medication.
Weiser noted that he is based in Israel, so it is easier to carry out studies in Eastern Europe than in the United States and that he knows researchers in Moldavia to be "trustworthy and experienced." Participants had to have a total PANSS score of 60 or greater.

Adjunctive estrogen patches significantly improve positive and negative symptoms of schizophrenia in premenopausal women, new research suggests.
That happens to also be the neurotransmitter dampened by Ketanserin.
So when subjects who took both LSD and Ketanserin didn’t experience the same perceptual transformations as those who took LSD alone, the researchers’ suspicions about the 5HT2A’s role in the changes caused by LSD were confirmed.
Psychedelics famously alter perception and have a profound effect on consciousness, prompting hallucinations and color and sound distortions, as well as causing time to seem to speed up or slow down.
Researchers from Yale University in the US and the University of Zurich in Switzerland, in an Oct.
The mechanics of this process—what happens in the brain to prompt these perceptual changes after someone takes LSD—are not well understood.
So, the neuroscientists set out to test the drug on 24 healthy subjects, giving some a psychedelic and others a placebo.
