Vasopressin and oxytocin release within the brain: a dynamic concept of multiple and variable modes of neuropeptide communication

Landgraf, Rainer, Neumann, Inga D.·2004·Frontiers in Neuroendocrinology

Abstract

As exemplified particularly with vasopressin and oxytocin, release of neuropeptides within the brain occurs from dendrites, somata, and axons of neurosecretory neurons; mechanisms include activation of intracellular Ca2+ stores, changed strength of synaptic input and altered interaction between transcription factors and gene promoters. Upon demand, both diffuse spread of neuropeptides in the extracellular fluid following dendritic release and focal release from axonal terminals may contribute to regionally and temporally varying combinations of neuromodulator and neurotransmitter actions, thus providing a theoretically unlimited variability in interneuronal signaling. Thus, instead of favoring volume or synaptic transmission following central neuropeptide release, a more dynamic concept is presented with multiple and variable modes of release and communication. This concept considers neuropeptides in the extracellular fluid of the brain rather than those in the cerebrospinal fluid or plasma as primary signals, triggering a variety of receptor-mediated effects, including those underlying behavioral and neuroendocrine regulation and psychopathology.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
