Topic: reward-predicting stimuli

The frontal cortex plays critical roles in learning and decision-making, particularly in representing reward-related variables such as reward magnitude and probability. Previous studies have identified frontal neural representations of these variables in expertly trained animals. However, it remains unknown how these representations emerge during learning from naive to expert. To address this gap, we use 2-photon microscopy to longitudinally record the activity of the same population of neurons in the dorsomedial frontal cortex. We record from head-fixed mice learning to perform Pavlovian or o
