Fig. 5. — Corticothalamic-induced slow oscillation is GABA_B-dependent. A, Control 7 Hz spindle oscillation recorded in a thalamocortical cell. B,Corticothalamic feedback stimulation, triggered by the bursts of the same LGN cell, slows down the oscillation at 2–3 Hz. C,The fast 7 Hz rhythm resumes after local application of the GABA_B antagonist CGP35348 (1 mm in micropipette) near the recording electrode. D, Graph representing the oscillation frequency of four cells recorded intracellularly versus experimental conditions: control (spindle); corticothalamic feedback (FB); and corticothalamic feedback in presence of CGP35348 (FB + CGP). For all cells, data points correspond to the latencies of the first peak of autocorrelation functions.
