Memory cells (motor cortex)
open-in-new
<p>Memory cells are found in the <a href="/facts/Primary_motor_cortex/DqdaQMNg">primary motor cortex</a> (M1), a region located in the posterior portion of the <a href="/facts/Frontal_lobe/RvokInmf">frontal lobe</a> of the brain. Their behavior is described by Bizzi et al. as: </p> <ul><li>In a baseline epoch (no force field on the end effector), they have one preferred direction</li> <li>In a force perturbation epoch, they show a change in the preferred direction</li> <li>In a subsequent washout epoch (no force field on the end effector), the change in preferred direction persists.</li></ul>
