Figure 4. Somatostatin interneurons influence salience processing in low but not high frequency bands.

Figure 4

LFP data converted to time/freq domain. (a) Log-scaled time-frequency spectra averaged across trials (<50) and 5 mice for each condition, and (b) averaged across post-stim time-points (30-450ms) show that deviant stimuli augment low-frequency induced power (relative to control) while low-gamma power is suppressed to redundant stimuli. (c-d) The former effect is absent after SOM-suppression, while the latter is not. Note that the magnitudes of control and redundant oscillatory power are nominally unchanged by SOM-suppression (scales are constant across all plots). (e-f) Low-pass filtered (4-14Hz) single trial traces show that deviant elicited low-freq enhancement lasts 1-2 cycles, is not phase locked, and is suppressed after SOM suppression (from 1 representative mouse). **p<.01.
