| Abstract: | The analysis of negative emotiogenic influence in dogs carried out according to dynamics of levels of acetylcholine and catecholamine content in peripheral blood and concomitant changes of the higher nervous activity, allows to conclude about the participation of both cholinergic and catecholaminergic neurotransmitter systems in reactions to this influence with a relative predominance of the first one. In animals with decreased reactivity and with compensatory abilities of the cholinergic system, the same influence leads to enhancement of the specific significance of the reaction of the catecholaminergic system, and especially of its transmitter, noradrenergic component. |
