An indoleamine neurotransmitter, 5-hydroxytryptamine, that is involved in depression, appetite, etc., and is crucial in maintaining a sense of well-being, security, etc
One of the neurotransmitters found in the brain Studies have shown that low levels of serotonin are associated with increased levels of aggression in animals
A neurotransmitter that is involved in mood (such as helping you to feel happy), sleep, mental health, blood pressure and heartbeat
A type of neurotransmitter - a brain chemical that carries messages between brain cells Low levels of serotonin in the brain are associated with feelings of depression
A neurotransmitter involved in many functions, including mood, appetite, and sensory perception
A brain chemical with several functions throughout the body, including mood regulation, pain perception, gastrointestinal function, and vasoconstriction In the brain, it functions as a neurotransmitter
(ser-o-TOE-nin) A brain chemical (neurotransmitter) that helps to regulate your mood A lack of it may lead to depression
A clinical transmitter found in many areas of the body including the brain where it is found in relatively high concentrations
a neurotransmitter formed from the amino acid tryptophan that regulates mood, sleep, appetite, and pain
An important neurochemical whose effects upon the human brain include mood elevation Production of serotonin in the brain is increased by ingestion of the amino acid tryptophan (a chemical precursor to serotonin) and the pharmaceutical anti-depressant Prozac (trademarked product of Eli Lilly & Company) In 1997, Marianne Regard and Theodor Landis discovered that humans afflicted with hemorrhagic lesions in the brain (cause of abnormal serotonin activation/production) often became "passionate culinary afficionados "
{i} essential hormone and neurotransmitter derived from the amino acid tryptophan, precursor of the hormone melatonin (Physiology)
An important multipurpose neurotransmitter involved in arousal, learning, and memory
a neurotransmitter that has many effects, including blood vessel constriction and smooth muscle stimulation
Serotonin is a chemical produced naturally in your brain that affects the way you feel, for example making you feel happier, calmer, or less hungry. a chemical in the body that helps carry messages from the brain and is believed to make you feel happy (serum + tonic + -in). Chemical (5-hydroxytryptamine, or 5-HT) derived from the amino acid tryptophan. It occurs in brain and intestinal tissue, platelets, and certain connective-tissue cells and is a component of many animal venoms (e.g., wasp, toad). A strong stimulator of blood-vessel constriction and a neurotransmitter, serotonin concentrates in certain brain areas, especially the midbrain and hypothalamus. Some cases of depression are apparently caused by reduced amounts or activity of serotonin in the brain; many antidepressants counteract that condition. Excessive brain serotonin activity may cause migraine headaches and nausea. LSD may act by inhibiting the action of serotonin
a key neurotransmitter that acts as a powerful constrictor of arteries, reducing the blood supply to the brain and contributing to the pain of headache
another neurotransmitter, it has been implicated in many central nervous system disorders Some of its functions seem to involve memory, appetite, sleep and learning Its chemical formula is C10H12N2O
A neurotransmitter implicated in the behavioural- physiological processes of sleep, pain and sensory perception, motor function, appetite, learning and memory
-a brain chemical (neurotransmitter) that relays messages between brain cells (neurons) It is one of the primary mood-regulating neurotransmitters It is derived from the amino acid tryptophan Serotonin can also be converted to melatonin
neurotransmitter in the brain that modulates mood, appetite, sexual activity, aggression, body temperature and sleep
Neurotransmitter that acts as a powerful constrictor of arteries, reducing the blood supply to the brain and contributing to the relief of headache pain
an inhibitory neurotransmitter required for sleep; its natural precursor is the essential amino acid tryptophan, found in relatively large quantities in bananas and milk
Neurotransmitter functionally significant in pain, sleep, and emotion; called also 5-HT, or 5-hydroxytryptamine
A neurotransmitter that plays a role in mood, sleep, and pain Serotonin may be involved in sleep
A neurotransmitter and hormone found in vertebrates, invertebrates and plants It is metabolised to 5-HIAA in the liver and then excreted in the urine Serotonin is measured on a blood specimen in cases of suspected carcinoid syndrome where it will be elevated The normal range is 101 - 283ng/ml
An indoleamine neurotransmitter, 5-hydroxytryptamine, that is involved in depression, appetite etc
Any of a class of drugs, such as fluoxetine or sertraline, that inhibit the uptake of serotonin in the central nervous system and are often used to treat certain mental illnesses, such as depression
