  • Title: Reaction of cats to species-specific acoustic signals during electrical stimulation of the hypothalamus before and after ablation of the sensorimotor region of the cortex.
    Author: Lyakso EE, Kulikov GA.
    Journal: Neurosci Behav Physiol; 1991; 21(5):408-16. PubMed ID: 1758620.
    Abstract:
    The possibility of the formation under chronic experimental conditions of a reaction of a selective character to species-specific acoustic signals (SAS) of the agonistic type, presented to cats against the background of subthreshold electrical stimulation of hypothalamic divisions, was demonstrated. Reactions appropriate to the SAS presented appeared only in those animals in which threshold electrical stimulation evoked directed aggressive reactions. Partial bilateral ablation of the sensorimotor region of the cortex (SMC) did not influence the selective character of the reaction to the SAS, but led to a change by comparison with the preoperative period in the relationship of the motoric and acoustic reactions of the agonist type to conjoint acoustic and electrical stimulation.
