... also differ. One way individuals can modulate social behavior is through experience-dependent modulation of the sensory systems that process social signals. Central monoamines (norepinephrine, dopamine, serotonin) modulate neural sensitivity to social stimuli and are key regulators of experience...

...Christopher A. Lowry; Kenneth J. Renner; Frank L. Moore Individual brain nuclei and regions of the central nervous system of adult male roughskin newts (Taricha granulosa) were microdissected and the concentrations of norepinephrine, epinephrine, 3,4-dihydroxyphenylacetic acid, dopamine, 5...

... may have a stimulatory role, since anatomical, pharmacological and physiological evidence is consistent with such a role. Norepinephrine probably inhibits motion sickness, as indicated by anatomical, physiological and pharmacological evidence. Information is missing that is critical...

... dorsomedially in the postobecular region of the medulla. The location of these dopamine-β-hydroxylase-immunoreactive neurons is similar to that in mammalian brains, i.e. in the locus coeruleus, lateral medullary tegmentum and area postrema. The presence of norepinephrine-synthesizing neurons in the above-listed...

...Pamela J. Hornby; Diane T. Piekut The organization of presumptive dopamine- and norepinephrine-synthesizing neurons in the brains of goldfish is described by using antibodies to tyrosine hydroxylase (TH) and dopamine β-hydroxylase (DBH) with avidin-biotin immunocytochemical techniques...

Brain stem and optic tectum concentrations of monoamine metabolites were also elevated after stress in high responders, but not in low-responsive fish...

... levels of serotonin (5-HT), 5-hydroxyindoleacetic acid (5-HIAA), and norepinephrine (NE) were higher in E2-IMP females relative to SHAM, and levels of 5-HIAA were higher in OVEX females relative to SHAM. Changes in dopamine (DA) activity were also found, with increased DA concentration and decreased...
