Fig. 4. GluR2Δ7-L7-Δγ2 mice have no gross abnormalities in spontaneous firing behavior in vivo.

(A) Raw examples of in vivo PC recordings from lobules I to V for all four groups. For (B) complex spike (CoSp) firing frequencies, (C) simple spike pauses following complex spikes, and (D) simple spike (SiSp) firing frequencies, no differences were found between controls and any of the mutant groups. (E) Unlike L7-Δγ2 mice, GluR2Δ7-L7-Δγ2 mice have no significantly higher simple spike regularity, as shown by the lower CV2 value. For complete statistics, we refer to table S3; *P < 0.05.
