(A) Confocal images showed ChR2 expression in PVs for both sham and FL slices. (B) An example of and averaged heat maps showed the inhibitory input from PVs to L2/3 PCs. (C) An example of and averaged heat maps showing the inhibitory input from PVs to a L5B PC. (D-F) Similar to above but for SOMs. (G) The IRF in L5B was significantly reduced in the FL group (sham, n=6, 3 mice; FL, n=6, paired t test, DF=5, 3 mice P=0.04). (H) Similar to G but for SOMs. IRF in L5B was also significantly increased in the FL group (sham, n=7; FL, n=7, unpaired t test, DF=6, P=0.014). (I) In sham L2/3 PCs, no difference between proximal and distal groups was found in IPSC charge from PVs. In FL mice L2/3 PCs, IPSC charge from PV INs was reduced in the distal group (P<0.05). (J) In both the sham and FL L5B PCs, no difference between proximal and distal groups was found in IPSC charge from PVs. (K-L) Similar to I-J but for SOMs. Note the significant difference in IPSC charge between proximal and distal groups for FL L2/3 PCs (P=0.000). See also Table S1.
