The olfactory thalamocortical system and odor reversal learning examined using an asymmetrical lesion paradigm in rats.


The olfactory thalamocortical system was disrupted bilaterally in rats using (a) unilateral mediodorsal thalamic (MD) lesions plus contralateral bulbectomy and transection of the anterior commissure (AC), (b) unilateral MD lesions plus contralateral lesions of the frontal cortex, or (c) bilateral MD lesions. Rats were trained on an odor discrimination task… (More)
