phenomena vary across the seasons and the molecular background for why
this happens was previously unknown. For this study, Dr. Jeffrey
and his team used a world-leading positron emission tomography (PET)
technology (originally created at CAMH by Dr. Alan Wilson) to detect
these seasonal variations in serotonin transporter binding (the process
that removes serotonin) in the living human brain and correlations
between serotonin binding and duration of daily sunshine.
Dr. Meyer explains, this is “an important lead in understanding how
season changes serotonin levels. This offers
an explanation for why
some healthy people experience low mood and energy in the winter, and
why there is a regular reoccurrence of depressive episodes in fall and
winter in some vulnerable individuals. The next steps will be to
understand what causes this change and how to interfere with it.”

(literally hydrates of carbon) are chemical compounds which act as the
primary biological means of storing or consuming energy; other forms
being via fat and protein. Relatively complex carboyhydrates are known
The simplest carbohydrates are monosaccharides, which are small
straight-chain aldehydes & ketones with many hydroxyl groups
added, usually one on each carbon except the functional group.
Other carbohydrates are composed of monosaccharide units, and break
down under hydrolysis. These may be classified as disaccharides,
oligosaccharides, or polysaccharides, depending on whether they have 2,
several, or many monosaccharide units.
