Effects of electrical stimulation of the lateral aspect of the prefrontal cortex upon attack behavior in cats.
An experiment was performed to determine the role of the lateral aspect of the prefrontal cortex upon quiet biting attack behavior elicited from the hypothalamus in the cat. The results of this experiment indicate that stimulation of 19 of 28 electrode sites sampled in the lateral prefrontal cortex produced a statistically significant inhibition of attack behavior elicited from the hypothalamus of the ipsilateral side. Stimulation of sites in the prefrontal cortex on the side contralateral to the hypothalamus from which attack was elicited had no effect upon this response. No systematic effect of prefrontal stimulation upon flight behavior was observed. Anatomical studies suggest that the lateral prefrontal cortex may inhibit attack behavior by modulating neurons in either the mediodorsal thalamic nucleus or ventral tegmental area.
