title: [Effect of blockade of the adrenergic structures of the hypothalamus on thermoregulatory reactions].
abstract: The blockade of alpha-adrenergic receptors of medial preoptic area detained the appearance of vascular thermoregulatory reaction and increased the threshold of the organism central temperature. The blockade of beta-adrenergic structures induced opposite effects. The excitatory efferent impulses from the thermosensitive neurons of the hypothalamus to thermogenic effectors and to the vasomotor system seem to be realized through the alpha-adrenergic structures of the brain, and the inhibitory--through the beta-adrenergic structures.
