Effects of SS (300 mg/kg, i.p.) on MGB. (A) Mean (±SEM, n=5) LFP input/output function to noise bursts recorded pre- and 2 h post-SS. LFP threshold increased approximately 20 dB after SS treatment. LFP amplitude was below normal at stimulation level below 70 dB SPL (blue arrow), but was approximately 30% greater than normal at 100 dB SPL (red arrow). (B) Discharge rate vs. frequency plots recorded at 60 dB SPL from a representative multiunit cluster pre- and 2 h post-SS. Note increase in firing rate Post-SS (red, up arrows). (C) Tuning curve showing threshold vs. frequency pre- and 2 h post-SS. The tuning curve is broader post-SS due to selective threshold elevation around the original characteristic frequency (CF) near 12 kHz.
