Top: Ratemeter record shows ongoing activity of an OFF-cell before and after improgan injection (at arrow below trace, Imp). Triangles indicate TF trials. Filled triangles indicate a withdrawal, open triangles no behavioral response within 10.6 s cut-off period. Examples of the reflex-related pause are shown on an expanded time base for selected trials (baseline, during TF inhibition, and following recovery).
Below: Ratemeter record shows ongoing activity of an OFF-cell before and after saline injection (at arrow below trace, Sal). Triangles indicate TF trials, with withdrawal throughout the protocol.
Ratemeter bins: 1 s. Sp/s: number of spikes per second.
