Abstract:
:Rabbits received ibotenic acid lesions of the mediodorsal nucleus of the thalamus (MD) or sham lesions. These animals were compared on 4 sessions of Pavlovian eyeblink and heart rate conditioning, in which a tone was the conditioned stimulus and a paraorbital electrical shock was the unconditioned stimulus. Lesions of MD retarded acquisition of the eyeblink conditioned response and abolished the late-occurring tachycardiac component of the heart rate conditioned response. The data are compatible with previous experiments suggesting that MD participates in the sympathetic control associated with somatomotor learning.
