PET scans help identify mechanism underlying seasonal mood changes
Brain scans taken at different times of year suggest that the actions of the serotonin transporter-involved in regulating the mood-altering neurotransmitter serotonin-vary by season, according to a report in the September issue of Archives of General Psychiatry, one of the JAMA/Archives journals. view more (2008-09-02)
LONG-LASTING RESULTS CAN BE OBTAINED WITH PSYCHOTHERAPY IN PANIC DISORDER
Panic disorder with agoraphobia is a chronic and disabling illness, with little spontaneous improvement. A report by a team of researchers of the Affective Disorders of the University of Bologna, headed by Professor Giovanni Fava, however, sheds a new light on the prognosis of the disorder. In the longest follow-up study published in the... view more... (2001-09-21)
Fluctuations in serotonin transport may explain winter blues

In the first study of its kind in the living human brain, Dr. Jeffrey Meyer and colleagues at the Centre for Addiction and Mental Health (CAMH) have discovered greater levels of serotonin transporter in the brain in winter than in summer. view more (2008-09-09)
Mood Lighting: Penn Researchers Determine Role of Serotonin in Modulating Circadian Rhythm
Researchers at the University of Pennsylvania School of Medicine have determined how serotonin decreases the body's sensitivity to light and that exposure to constant darkness leads to a decrease in serotonin levels in the brain of fruit flies. view more (2005-07-11)
Light-induced hormone surge points to benefits of light therapy
A report in the November Cell Metabolism reveals powerful effects of light on the adrenal glands, a finding that might explain the broad benefits of bright light therapy for a variety of conditions, including sleep and depressive disorders, according to researchers. view more (2005-11-09)

New Evidence on How our Eyes use Light to Manage our Body Clock - University of Surrey Groundbreaking Study Results
A new study published this week shows for the first time that the human eye is sensitive to short wave length visible light and transmits information to the body clock in a way that may make it possible to manipulate waking and sleeping rhythms. This new data, gained from a study carried out at the University of Surrey, might enable this type of... view more... (2001-08-20)
