Here we report an extremely early seasonal growth (before February) of the song control nuclei HVC and RA in Corsican blue tits (Parus caeruleus) indicating that the vernal development of these nuclei occurs well before the vernal increase in plasma testosterone, testes size and song activity.
Various effects, from the development of primary nuclei on storage to a general decrease of the fictive temperature, have been considered.
The resulting impaired development of autonomic nuclei affects both parasympathetic and sympathetic control, and leads to symptoms such as profuse sweating, low heart rate variability, syncopal episodes, impaired pupillary regulation, and poor temperature control [6], [39], [40].
Moreover, it is well known that both the development of brain nuclei directly involved in stress responses (eg the locus ceruleum, Kubo et al. 2001) and the HPA axis are sensitive to sex steroid hormones (Viau 2002).
The transcription factor Phox2b is necessary for the development of the nucleus of the solitary tract (NTS).
The development of the nucleus occurred after the split between Bacteria and this common ancestor.
In the LC, for example, enriched genes included the presynaptically located α2A- receptors and adrenergic transporters, catecholamine synthesizing enzymes (tyrosine hydroxylase, DOPA decarboxylase and dopamine-β-hydroxylase) and the transcription factors PHOX2A and PHOX2B which are involved in the development of this nucleus [23].
Interestingly, Ngn3 regulates the development of ARC nucleus neurons.
It was based on a community health care model for the development of gerontological nucleus.
The development of the nucleus replacement could provide a promising way to break through the present clinical limitations.
