  2. Dopamine - Wikipedia

    en.wikipedia.org/wiki/Dopamine

    The higher the level of dopamine activity, the lower the impetus required to evoke a given behavior. [53] As a consequence, high levels of dopamine lead to high levels of motor activity and impulsive behavior; low levels of dopamine lead to torpor and slowed reactions. [53]

  3. Dopaminergic pathways - Wikipedia

    en.wikipedia.org/wiki/Dopaminergic_pathways

    The dopamine neurons of the dopaminergic pathways synthesize and release the neurotransmitter dopamine. [2] [3] Enzymes tyrosine hydroxylase and dopa decarboxylase are required for dopamine synthesis. [4] These enzymes are both produced in the cell bodies of dopamine neurons. Dopamine is stored in the cytoplasm and vesicles in axon terminals.

    An addictive drug is defined as a substance that affects the mesolimbic system directly or indirectly by increasing extracellular levels of dopamine. [ 24 ] Common addictive substances such as cocaine , alcohol , and nicotine have been shown to increase extracellular levels of dopamine within the mesolimbic pathway, preferentially within the ...

    en.wikipedia.org/wiki/Dopamine_receptor

    Dopamine receptors are implicated in many neurological processes, including motivational and incentive salience, cognition, memory, learning, and fine motor control, as well as modulation of neuroendocrine signaling. Abnormal dopamine receptor signaling and dopaminergic nerve function is implicated in several neuropsychiatric disorders. [2]

  9. Central nervous system fatigue - Wikipedia

    en.wikipedia.org/wiki/Central_Nervous_System_Fatigue

    In the brain, serotonin is a neurotransmitter and regulates arousal, behavior, sleep, and mood, among other things. [9] During prolonged exercise where central nervous system fatigue is present, serotonin levels in the brain are higher than normal physiological conditions; these higher levels can increase perceptions of effort and peripheral muscle fatigue.
