Paired-pulse (PP) ratios computed using the individual baseline method. A: illustration of the PP ratio measurement with respect to an individual baseline for each IPSP, determined from the prestimulation artifact for that particular IPSP. In B–J, the open circles show mean P8 ratios, gray circles show mean P16 ratios, and filled circles show mean P27 ratios. B–D: mean PP ratios for combined IPSPs at 5 Hz (B), 10 Hz (C) and 50 Hz (D). n = 10, 15, and 12 cells for P8, P16, and P27, respectively. n values after PP2 were slightly lower at 5 and 10 Hz. PP ratios were lower at P8 at 5 and 10Hz, and PP ratios were lower at all ages at 50 Hz. E–G: mean PP ratios for GABAA IPSPs at 5 Hz (E), 10 Hz (F), and 50 Hz (G). n = 6, 8, and 6 cells for P8, P16, and P27, respectively. H–J: mean PP ratios for GABAA IPSCs at 5 Hz (H), 10 Hz (I), and 50 Hz (J). n = 4, 4, and 3 cells for P8, P16, and P27, respectively.
