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.
Anhedonia is a diverse array of deficits in hedonic function, including reduced motivation or ability to experience pleasure. [1] While earlier definitions emphasized the inability to experience pleasure, anhedonia is currently used by researchers to refer to reduced motivation, reduced anticipatory pleasure (wanting), reduced consummatory pleasure (liking), and deficits in reinforcement learning.
Several theories concerning the biologically based cause of depression have been suggested over the years, including theories revolving around monoamine neurotransmitters, neuroplasticity, neurogenesis, inflammation and the circadian rhythm. Physical illnesses, including hypothyroidism and mitochondrial disease, can also trigger depressive ...
A dopamine molecule consists of a catechol structure (a benzene ring with two hydroxyl side groups) with one amine group attached via an ethyl chain. [14] As such, dopamine is the simplest possible catecholamine, a family that also includes the neurotransmitters norepinephrine and epinephrine. [15]
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).
Pleasure is experience that feels good, that involves the enjoyment of something. [1] [2] It contrasts with pain or suffering, which are forms of feeling bad. [3]It is closely related to value, desire and action: [4] humans and other conscious animals find pleasure enjoyable, positive or worthy of seeking.
The combination of dopamine, serotonin and oxytocin is already pretty dreamy, but the brain takes that natural high to the next level when you reach the big O by releasing endogenous (i.e., made ...
Happiness is primarily controlled by the levels of dopamine and serotonin in the body. Both are monoamine neurotransmitters that act on different sites in the body. Serotonin acts on receptors in the gastrointestinal tract while dopamine acts on receptors in the brain, while both performing similar functions. [16]
