Circadian variation of food intake and digestive tract contents in the rat.

abstract：:Rats with either control operations or septal damage were pretrained on a VI 30-sec schedule and tested for response suppression ability on either an omission training (OT) task or on extinction. Septal damage enhanced barpressing on the VI 30-sec task. Animals with septal damage took longer to suppress responding on ...
