Figure 4.
Ion concentrations during gamma oscillations in the PY–IN network in the presence of 8 mm potassium in the bath solution. A, Raster plot showing activity for a representative part of the PY and IN populations. B, Voltage traces from representative PYs and IN cells. C, KOUT+ and ClIN− concentrations during network activity. D, LFP computed from PY activity and, below, power spectrum of LFP signal.
