Anatomy of the brain neurogenic zones revisited: Fractones and the fibroblast/macrophage network
TLDR
Structural and ultrastructural evidence for highly organized extravascular BL, unique to the SEL, are reported and it is suggested that the structure described is implicated in adult neurogenesis, gliogenesis, and angiogenesis.
Function-related plasticity in hypothalamus.

    Annual review of neuroscience

TLDR
Physiological activation of the mag nocellular hypothalamo-neurohypophysial system induces a coordinated astrocytic withdrawal from between the magnocellular somata and the parallel-projecting dendrites of the supraoptic nucleus, which results in interneuronal coupling increases that are capable of being modulated synaptically via second messenger-dependent mechanisms.
Emerging concepts of structure-function dynamics in adult brain: The hypothalamo-neurohypophysial system

  • 31 December 1990
TLDR
Progress in developing an ever more complete structural and functional picture of this system has been closely tied to advancements in technology, specifically in the areas of radioimmunoassay, immunocytochemistry, anatomical tracing methods at the light and electron microscopic levels, and sophisticated preparations for electrophysiological investigation.
Oscillatory bursting of phasically firing rat supraoptic neurones in low‐Ca2+ medium: Na+ influx, cytosolic Ca2+ and gap junctions.
TLDR
The results suggest that intrinsic burst activity in SON neurons perifused with low‐Ca2+ or Ca(2+)‐free medium involves enhanced Na+ influx through persistent Na+ channels, and requires the presence of rapid intracellular Ca2+ mobilization that might also explain the selective existence of oscillatory bursting in phasically firing cells.
Subnuclei in the rat hypothalamic paraventricular nucleus: A cytoarchitectural, horseradish peroxidase and immunocytochemical analysis
TLDR
The results suggest that neurophysin-containing cells of the paraventricular nucleus are relatively segregated into neurohypophysial- projecting and brainstem/ spinal cord-projecting groups and that release of hormone from the neurohypophysis does not necessarily imply a coincidental release of hormones into other extrahypothalamic sites.
Pituicytes, glia and control of terminal secretion.

    The Journal of experimental biology
  • 1 September 1988
TLDR
Studies of isolated neurohypophysis and of cultured adult rat pituicytes have shown that these glia undergo appropriate morphological changes in response to osmotic stimuli or to receptor-mediated activation of adenylate cyclase, thought to be effectors of the alterations seen in vivo.
Astrocytic Plasticity and Patterned Oxytocin Neuronal Activity: Dynamic Interactions
TLDR
The results indicate that suckling elicits dynamic glial neuronal interactions in the SON; GFAP plasticity dynamically reflects OT neuronal activity, which is in line with previous work on astroglial–neuronal interactions.
Calbindin‐D28k: role in determining intrinsically generated firing patterns in rat supraoptic neurones.
TLDR
The data suggest that firing activities in SON cells are dependent on Ca(2+)‐dependent depolarizing after‐potentials and that calbindin, acting as an endogenous Ca2+ buffer, is involved in regulation of intrinsic firing patterns.
Ca2+ release from internal stores: role in generating depolarizing after‐potentials in rat supraoptic neurones.
TLDR
Ca2+ influx via high‐voltage‐activated Ca2+ channels in SON cells triggers ryanodine receptor‐mediated Ca2-mediated release from internal stores, which enhances DAPs and promotes phasic firing in Son cells, and would thus contribute to vasopressin release.
Connexin 26 and basic fibroblast growth factor are expressed primarily in the subpial and subependymal layers in adult brain parenchyma: Roles in stem cell proliferation and morphological plasticity?
TLDR
The present results are consistent with the hypothesis that all of these various cell types may communicate in a cooperative network.
