[The effect of cholino- and adrenoblockers on limbic-sympathetic evoked potentials].

Effects of i.v. administration of cholino- and adrenergic blocking agents on limbic-sympathetic discharges of L2-L3 white rami, evoked by stimulation of the anterior, visceral area of the limbic cortex and on arterial blood pressure were studied in anesthetized cats.

[Discharges in the white rami communicantes evoked by stimulation of different fields of the limbic system].

Electrical responses to stimulation of different areas of the cingulate gyrus were studied in L2-L3 white rami in anesthetized and immobilized cats. The stimulation evoked a sympathetic discharge mostly consisting of a wave with a mean latency of 71.2 +/- 2.

[Characteristics of the response of the white rami communicantes to stimulation of different sections of the amygdaloid body].

Electrical responses in L2-L3 white rami to stimulation of cortico-medial, baso-lateral and central amygdaloid nuclei were studied in anesthetized and immobilized cats. The stimulation evoked a similar pattern of sympathetic discharge mostly consisting of a wave with a mean latency of 69.04 +/- 1.

[Mechanism of change in vasomotor sympathetic activity after stimulation of various amygdaloid structures].

The influence of low- and high-frequency stimulation of cortico-medial, baso-lateral and central nuclei of the amygdala was studied in anesthetized cats by means of recording arterial blood pressure and electrical activity of the amygdala. The induced vasomotor effects were compared with the effect of hypothalamic stimulation. The low-frequency stimulation of all amygdaloid nuclei induced depressor reactions, while the high-frequency stimulation of the same areas induced an obvious pressure response.

[Responses of pericruciate cortex neurons to stimulation of the hypothalamus and reticular formation].

Neurons of the pericruciate cortex revealed a high degree of reactivity to stimulation of posterior hypothalamus (HP) and mesencephalic reticular formation (RF)--94 and 88% resp., and a marked convergence of upward discharges from HP and RF (73.5%) in anesthetized and immobilized cats.
