What is serotonin. Serotonin is often referred to as the "feel-good" neurotransmitter, Freimuth says. When levels are normal, you're more likely to feel happy and emotionally stable.
Serotonin (/ ˌ s ɛr ə ˈ t oʊ n ɪ n, ˌ s ɪər ə-/) [6] [7] [8] or 5-hydroxytryptamine (5-HT) is a monoamine neurotransmitter.Its biological function is complex, touching on diverse functions including mood, cognition, reward, learning, memory, and numerous physiological processes such as vomiting and vasoconstriction.
Endorphins inhibit transmission of pain signals by binding μ-receptors of peripheral nerves, which block their release of neurotransmitter substance P. The mechanism in the CNS is similar but works by blocking a different neurotransmitter: gamma-aminobutyric acid (GABA).
Since doing activities you enjoy can increase dopamine—the neurotransmitter responsible for happiness, satisfaction, motivation, and more—the items on your list should ideally do just that ...
Dopamine is also synthesized in plants and most animals. In the brain, dopamine functions as a neurotransmitter—a chemical released by neurons (nerve cells) to send signals to other nerve cells. Neurotransmitters are synthesized in specific regions of the brain but affect many regions systemically.
Another part of this sexy equation is serotonin—a neurotransmitter and hormone, commonly referred to as the “happy chemical,” that plays a role in regulating mood.
In Happy People Live Longer (2011), [132] Bruno Frey reported that happy people live 14% longer, increasing longevity 7.5 to 10 years and Richard Davidson's bestseller (2012) The Emotional Life of Your Brain argues that positive emotion and happiness benefit long-term health.
Neurotransmitters are generally stored in synaptic vesicles, clustered close to the cell membrane at the axon terminal of the presynaptic neuron. However, some neurotransmitters, like the metabolic gases carbon monoxide and nitric oxide, are synthesized and released immediately following an action potential without ever being stored in vesicles ...
