Topic: whisker movement

In the mouse whisker system, somatosensory thalamus outputs to primary and secondary vibrissal somatosensory cortices (vS1 and vS2), as well as the dysgranular zone, a strip of cortex between the vibrissal and forepaw primary somatosensory cortices. Despite extensive studies of vS1 and vS2, the dysgranular zone’s response to whisker touch remains unknown. Vibrissal S1 sends outputs to three areas within the dysgranular zone: the anteromedial (AM), centromedial (CM), and posteromedial (PM) areas, each of which shows robust responses to whisker touch. We trained mice trimmed to two whiskers to a
