Amygdalo-striatal interaction in the enhancement of stimulus salience in associative learning.

abstract：:This study was prompted by reports of functionally normal humans with micrencephaly or cortical hypoplasia. Methylazoxymethanol acetate (MAM) treatment, which induces micrencephaly in rats, was administered by injection (20 mg/kg) on gestational day 14. Prior to weaning and into adulthood, offspring were assessed on m...
