Cortical microcircuitry of executive control in supplementary eye field

Medial frontal cortex contributes to response monitoring and executive control, but the microcircuitry enabling this function is unknown. We recorded neural spiking across all layers of supplementary eye field, an agranular medial frontal area, in monkeys performing a saccade-countermanding (stop signal) task. We identified neurons that modulated after successful stopping that we believe are related to conflict monitoring and goal maintenance. Neurons with these different profiles of activation had different spike widths, time courses of activation, and were concentrated differently across layers. In this talk, I aim to present these findings and generate an informal discussion about their importance of these findings, and more generally, how to prepare and present them moving forward.
