Representative example of A1 activity during exposure to 50 upward FM sweeps (2–16 kHz range; CF 7.34 kHz) before, during, and after contralateral deactivation of core auditory areas. PSTH and corresponding raster example of a single unit in A1 before contralateral cooling (phase 1, A), during contralateral A1 cooling (phase 3, B), during simultaneous contralateral A1 and AAF cooling (phase 5, C), during contralateral AAF cooling (phase 7, D), and during the contralateral rewarm stage (phase 9, E). Gray lines across left column delineate warm (top, phase 1) response level to facilitate comparisons across cooling conditions.
