| To investigate the neural mechanisms underlying top-down/bottom-up behavioral adaptation, we recorded cortical hemodynamics in the prefrontal cortex (PFC) by functional near-infrared spectroscopy (fNIRS) while a subject performed a behavioral task in which the subject learned stimulus-response associations and was required to adapt his/her response when the relationships between the stimulus and the response changed (reversal learning). In this task, we employed two reversal conditions: whole and partial reversal conditions. Under the whole reversal condition, the stimulus-response associations changed for all stimuli so that the subjects were able to prospectively adapt their behavior after the reversal on the basis of their knowledge of prior stimulus-response associations. This type of reversal learning corresponds to top-down behavioral adaptation. Under the partial reversal condition, only a portion of stimuli changed their contingency so that the subjects needed to relearn the stimulus-response associations after the reversal. This type of reversal learning corresponds to bottom-up behavioral adaptation. We found a significant increase in the oxyhemoglobin (oxy-Hb) concentration in the first block after the whole reversal, and a significant decrease in the first block after the partial reversal. These results indicate that the PFC is especially important for top-down behavioral adaptation. | ||||||||||
