Serotonin is one of several chemical messengers in the brain, or neurotransmitters, which help brain cells communicate with one another. Among many other functions, serotonin is involved in regulating mood. Problems with making or using the right amount of serotonin have been linked to many mental disorders, including depression, bipolar disorder, anxiety disorder, autism, and schizophrenia.
Neurons talk to each other using chemical signals called neurotransmitters. Scientists at St. Jude Children's Research Hospital have drawn on structural biology expertise to determine structures of vesicular monoamine transporter 2 (VMAT2), a key component of neuronal communication.
Neurobiologists from Immanuel Kant Baltic Federal University found out differences of educability level and processes of formation of spatial memory of adult male and female rats, that live together in large cages and played with toys.
Neurons and astrocytes are the two types of cells required by the brain to enjoy the scent of morning coffee and freshly baked cookies or to discern the warning smell of something burning.
Cognitive deficits accompany mood disorders and other psychiatric conditions, often with debilitating effects.
Because serotonin is one of the primary chemicals the brain uses to influence mood and behavior, it is also the most common target of psychiatric drugs.
Worms may not be depressed. However, this does not prevent them from benefiting from antidepressants.
Breaking a longstanding impasse in our understanding of olfaction, scientists at UC San Francisco (UCSF) have created the first molecular-level, 3D picture of how an odor molecule activates a human odorant receptor, a crucial step in deciphering the sense of smell.
Location, location, location is the key for psychedelic drugs that could treat mental illness by rapidly rebuilding connections between nerve cells.
Long-term consumption of Allura Red food dye can be a potential trigger of inflammatory bowel diseases (IBDs), Crohn's disease and ulcerative colitis, says McMaster University's Waliul Khan.
Quark and cheese are primarily casein-based in terms of protein content. The stomach’s digestion of casein results in the production of protein fragments (peptides) that have an unpleasant flavor, despite casein itself not having a bitter flavor.
It can be crippling for those who suffer from conditions like depression, anxiety, and cluster headaches. In clinical research, psychedelic substances have demonstrated benefits as therapies for several ailments, but not in all cases.
Depression is a common mental health condition that affects approximately 1 million Australians each year. It is a significant risk factor for suicide, the leading cause of death in young adults.
Three members of a family of proteins have been identified that are important to helping us fine tune the activity of brain chemicals which enable us to walk or stand at will, scientists report.
An international consortium of leading migraine scientists identified more than 120 regions of the genome that are connected to risk of migraine.
The World Health Organization estimates that nearly 280 million people worldwide suffer from depression.
A group of scientists identified that a prevailing drug for treating constipation might boost an individual’s capability to think with better clarity.
A new study published in Nature Communications suggests that gene therapy delivered into the brain may be safe and effective in treating aromatic L-amino acid decarboxylase (AADC) deficiency.
Newly devised gene therapy can help children born with AADC, a rare genetic disorder that causes developmental and physical disabilities.
For the first time, scientists have linked distinct patterns of genetic mutations with OCD in humans using genome-wide analysis.
A class of drug called monoamine oxidase inhibitors is commonly prescribed to treat depression; the medications work by boosting levels of serotonin, the brain's "happiness hormone."
