Secondary Motor Cortex: Where ‘Sensory’ Meets ‘Motor’ in the Rodent Frontal Cortex

There is rapid progress towards understanding the function of M2. Progress is fueled by accessibility of the region for optical imaging and optogenetics, as well as the development of sophisticated decision-making tasks for rodents. M2 receives sensory information from reciprocal connections with sensory, parietal, and retrosplenial cortices. It exerts control on actions by projecting to various motor-related subcortical regions. Removal of M2...
