Figure 3. — Puff activation of perforant path recruits mainly IPSCs in GCs and mainly EPSCs in FS interneurons. A, Twenty second voltage-clamp responses (black) of a GC clamped at −40 mV in control (ctrl) (top) and after puffing 100 mm KCl to perforant path (bottom). Gray traces are 1 s of the trace enlarged to display individual IPSCs and EPSCs. B, Same as A, but for a FS interneuron (FS IN). C, Rasters for recordings made in a GC in control trials (top) and puff trials (bottom) marking IPSC arrival times (magenta dashes) and EPSC arrival times (cyan dashes). Each row represents a separate trial. Magenta and cyan lines show smoothed counts for IPSCs (magenta) and EPSCs (cyan) across trials. Puff stimulus was delivered at time = 1 s. D, Same as C, but for a FS IN.
