Unit activity changes elicited in amygdala and neocortex of anaesthetized rats by intraperitoneal injection of lithium chloride.
Intraperitoneal injection of 0.15 M LiCl (2% body weight) to anaesthetized rats elicited, after a 6 min latency, discharge of about 50% units i basolateral amygdala (n = 27). The activation lasted for 15 min on the average. Cortical neurones were not affected by the LiCl injection. It is suggested that the amygdalar reaction to LiCl administration may account for the association of the gustatory trace with the visceral signals of poisoning which mediates acquisition of conditioned taste aversion under anaesthesia.
