Abstract:
Marked weight gain was observed in female rats given small electrolytic lesions in the dorsal posterior portion of the amygdala. With a standard lab pellet diet, weight gains typically ranged between 20-30 g during the first 3 postoperative days, and between 60-100 g over the first 20 days. Rats with sham lesions generally gained only 5-15 g in 20 days. The results are consistent with much older studies that reported obesity in cats, dogs, and primates with lesions of the amygdala.
