Food-induced arousal in Aplysia is characterized by a progressive increase in the speed and strength of biting responses elicited by a seaweed stimulus. Data from semi-intact and dissected preparations suggest that the identified, serotonergic, metacerebral cells (MCCs) of the cerebral ganglion contribute to food-induced arousal by enhancing the strength of buccal muscle contractions, and by mo...

Chronic stress has been known to potentiate addictive behaviours in both human addicts and experimental animals. In the present study, chronic mild food restriction was used as a stressor to investigate its effect on the locomotor simulant effects of cocaine as well as FosB expression in the nucleus accumbens and caudate putamen. Chronic mild food restriction enhanced the locomotor response to ...
