This transition is amygdala- and corticosterone-dependent. Microarray results showed downregulated dopaminergic presynaptic function in the amygdala with preference learning. Corticosterone injected 8-day-old pups and untreated 12-day-old pups learn aversions and had dopaminergic upregulation in the amygdala. 8 day saline or corticosterone treated- or 12 day old untreated rat pups were trained with odor-shock pairings. Immediately after training pups were sacrificed and the amygdala dissected out. Controls were unpaired shock-odor groups.Paired and unpaired groups were processed together for each experimental condition. Paired and unpaired data were compared by ranked products.http://www.ebi.ac.uk/arrayexpress/experiments/E-GEOD-17651rathttp://www.ebi.ac.uk/arrayexpress/experiments/E-GEOD-17651/samples/
