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.
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."
Many people live with chronic pain, and in some cases, cannabis can provide relief. But the drug also can significantly impact memory and other cognitive functions.
Low levels of serotonin in the brain are seen as a possible cause of depression and many antidepressants act by blocking a protein that transports serotonin away from the nerve cells.
Researchers at the University of California, Davis, have created a genetically encoded sensor for detecting hallucinogenic substances.
Serotonin, or 5-hydroxytryptamine (5-HT), is a kind of neurotransmitter. 5-HT can regulate multifaceted physiological functions such as mood, cognition, learning, memory, and emotions through 5-HT receptors.
Asthma is a condition in which a person’s airways turn hyperresponsive.
A tiny population of neurons known to be important to appetite appear to also have a significant role in depression that results from unpredictable, chronic stress, scientists say.
Having a choice of foods may accelerate aging and shorten the lifespan of fruit flies, according to a study published today in the open-access eLife journal.
The sweet taste of sugar is very popular worldwide. In Austria and Germany, the yearly intake per person adds up to about 33 and 34 kilograms, respectively. Thus, sugar plays an increasingly role in the nutrition and health of the population, especially with regard to body weight.
In first-of-their-kind observations in the human brain, an international team of researchers has revealed two well-known neurochemicals -- dopamine and serotonin -- are at work at sub-second speeds to shape how people perceive the world and take action based on their perception.
