Serotonin can chemically attach to histone proteins in the cell nucleus to help regulate gene expression. The findings may provide a better understanding of an array of psychological disorders and neurodegenerative diseases.
Researchers report LSD triggers a reduction in functional connection between areas of the brain that govern cognitive processes, while increasing connectivity in brain networks associated with sensory functions.
A new study implicates serotonin neurons in the nucleus accumbens with social behavior in mouse models of ASD. When serotonin release was triggered, researchers noted social behaviors normalized.
Researchers have confirmed previous findings linking abnormalities in serotonin to sudden death in infants. It is hoped the findings will help other researchers to develop biomarkers to identify infants at increased risk of SIDS.
A new paper may help answer some questions as to why some infants die suddenly. Looking at blood samples from infants who had died of SIDS, researchers discover 31% of the children had elevated levels of serotonin. The researchers concluded that abnormal serotonin metabolism could indicate an underlying vulnerability that increases SIDS risk.
Long term stimulation of the serotonin system makes mice more active, a new study reports.
Researchers have identified two groups of serotonin neurons that may help to suppress aggression in mice.
Serotonin and arginine-vasopressin act in opposite ways in males and females to influence aggression and dominance, researchers report.
