Cortical recruitment determines learning dynamics and strategy

ENP/DIM PhD student Sebastian CEBALLO and coll. in the ENP group of Brice BATHELLIER just published an article in Nature Communications about the neural basis of preference for the most salient stimulus within two presented stimuli such that the more salient of the two is associated more strongly with the unconditioned stimulus, leading to overshadowing. Using trained mice to discriminate optogenetically driven response patterns that elicit different levels of cortical activity, the authors demonstrate the role of cortical recruitment as a neuronal correlate of stimulus salience.
