    Changes in AMPAR, NMDAR, and GABAaR components of the synaptic response during epileptiform activity in ERC with a partial block of NMDA-receptors by intracellular MK-801. Top and bottom-left panels represent the estimates of AMPAR-, NMDAR-, and GABAaR-mediated components of the response to the extracellular stimulus under control conditions (black traces) and during epileptiform activity (red traces). Note the substantial block of NMDAR-mediated conductance by intracellular MK-801 (compare with Figure 2 ). Bar charts (bottom-right) represent the peak AMPAR-mediated conductance and the area under the plot: despite the partial block by intracellular MK-801, the response significantly increased (paired Student’s t -test, P = 0.03, asterisk (*) indicates significant difference); however, no changes in the area under the plot were detected (paired Student’s t -test, P = 0.27).
