Simultaneous Targeting of Shared Laminar Computations in Premotor and Primary Motor Cortices
When we want to pick an apple up off a table, we go through two steps: planning and execution. Our brain must first plan how far and how fast to reach, and then it must send signals to arm muscles to execute this plan. Planning related signals are generally seen in the premotor cortex whereas execution related signals are seen in the primary motor cortex. However, we are unsure of how planning related signals are transformed into execution related signals, and how these signals are moved from premotor cortex to primary motor cortex, as these two areas are two anatomically different areas of the brain. The goal of this project is to determine how these two areas share signals to coordinate movement by designing a fixture to hold two electrodes in both areas at the same time and then comparing how the signals correlate with one another.
