DE does not alter the short-term depression of TRN inhibition to dLGN. Short-term depression measured by optogenetic activation of ChR2-expressing TRN axons in dLGN. Left, Normalized average eIPSC amplitudes across different stimulation frequencies (5, 10, and 20 Hz). Plot, Mean ± SEM. Right, Example average eIPSC traces across different stimulation frequencies from NR and DE. Two-way ANOVA; 5 Hz stimulation train: F(9,234) = 0.6041, p = 0.7930; 10 Hz stimulation train: F(9,234) = 0.5854, p = 0.8086; 20 Hz stimulation train: F(9,234) = 1.128, p = 0.3438. NR, n = 14 cells from 3 mice; DE, n = 14 cells from 4 mice.
