Reduced frequency and mixed effects on sEPSC amplitude after CSD in vitro. (
A
) sEPSCs recorded in Layer 2/3 pyramidal neurons at 5 and 30 mins post-CSD. (
B
) sEPSC frequency is consistently decreased 5 and 30 min after CSD (lengthened interevent interval, rightward shift as shown in cumulative plots; 5 min:
P
= 1.62 × 10
−8
, 30 min:
P
= 2.17 × 10
−15
; 2 sample KS test; 5 min post-CSD,
n
= 5 cells, 5 mice and 30 min post-CSD,
n
= 7 cells, 7 mice). (
C
) sEPSC amplitude was decreased at 5 min post-CSD (
P
= 3.02 × 10
−4
; KS test) but increased at 30 min (
P
= 1.72 × 10
−4
; 2-sample KS test; 5 min post-CSD:
n
= 5 cells, 5 mice and 30 min post-CSD:
n
= 7 cells, 7 mice). Magnified cumulative plot below shows large amplitude events (greater than −70 pA) that were only evident in post-CSD groups. Magnified cumulative plot on right including only less than −60 pA events shows clear rightward shift (smaller amplitudes) at 5 min and leftward shift (larger amplitudes) 30 min after CSD.
