Relative amplitude decrease of granular sink after both cortical silencing approaches

	Untreated	Drug condition	% decrease
Muscimol (0.2–1 μg/μl; n = 10)
BF	−1.111	−0.134	87.9
±1 octave	−0.677	−0.05	92.6
±2 octave	−0.233	−0.041	82.5
Muscimol/SCH50911 (1:1.5; n = 3)
BF	−1.044	−0.103	89.74
±1 octave	−0.796	−0.107	86.51
±2 octave	−0.621	−0.079	87.24

Comparative mean peak amplitudes (millivolts per square millimeters) and relative decrease of the granular sink shown for both pharmacological silencing methods. Note that, although relative decrease is similar in both cases, the amplitudes for nearBF stimulation (±1–2 ocatves) are higher after cortical silencing with muscimol and SCH50911 applied concomitantly.
