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.
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.
Not much is known about the fundamental mechanisms in the brain of hallucinogenic drugs and the way they induce their hallucinogenic effects.
Gastric cancer is one of the major causes of cancer-related mortality around the world. It is known for its potential to spread across the peritoneal cavity.
Researchers at the University of Copenhagen have mapped a novel structure of what is called a “neurotransmitter: sodium symporter.”
