A study in fruit fly models of autism reveals sleep disruption associated with the neurodevelopmental disorder is associated with elevated levels of serotonin. The origin of the higher levels of serotonin was discovered to be in glial cells in the blood-brain barrier.
PsychLight, a newly developed genetically encoded fluorescent sensor, helped researchers identify a psychedelic compound that acts on beneficial neural pathways to treat psychiatric disorders without the hallucinogenic effect.
A recent study found 42% of participants gained, on average, 29 lb of unwanted weight during the pandemic, with people gaining 1.5lb per month. Researchers say a combination of stress, hormones, and dwindling motivation to exercise during the lockdowns may be to blame.
While the effects of hallucinogens to treat mental illnesses are being researched, little is known about the neurobiology of those who dabble in psychedelics for recreational purposes. A new study reports "psychonauts" have distinct behaviors, including taking a scientific approach to documenting their experience with hallucinogens, compared to more recreational users.
Airway hyperresponsiveness in asthma induced by methacholine is partly due to mast cells, a new study reports.
LSD increases social behaviors by activating 5-HTPA serotonin receptors and AMPA receptors in the prefrontal cortex, and the mTORC1 protein. Activating all three factors promoted social interactions. The findings suggest supervised LSD microdosing may help alleviate some of the social problems associated with ASD and other mental health disorders that impact social behaviors.
Artificial intelligence technology redesigned a bacterial protein that helps researchers track serotonin in the brain in real time.
Researchers investigate how laughter improves both mental and physical well-being.
A new study reveals specific brain regions that individually promote patience through the action of serotonin.
