title: [The electrical activity of the hypothalamic arcuate nucleus and the morphofunctional characteristics of the gonads in birds during blockade and stimulation of the beta-adrenergic receptors].
abstract: Beta-adrenoreceptors agonist isadrine as shown by measurement of hypothalamic arcuate nucleus (AN) summary electrical activity and by morphometry of its neurons and testis does not result in significant acceleration of maturation in maturing (4-6 week old) male japanese quails (Coturnix coturnix japonica). Anapryline-induced blockade of beta-adrenoreceptors leads to small inhibiting of the reproductive complex. This findings confirm our previous works, according to which brain beta-adrenergic system does not play leading role in regulation of maturation in birds. The direct correlation between morphometrical and electrophysiological features of AN neurosecretory cells was demonstrated as well.
