NMDA-mediated sEPSC and evoked EPSC rise times do not change during ON/OFF sublamination. EPSCs were recorded at +40 mV.A, Average sEPSCs from a P16 cell (top) and a P29 cell (bottom) in control (black trace) and CNQX (gray trace) conditions.B, The normalized rise time (rise time/amplitude) of sEPSCs is slightly increased in the presence of CNQX; however, the effect is similar in both younger (filled bar) and older (open bar) cells. C, Optic tract-evoked EPSCs from a P16 cell (top) and a P28 cell (bottom). D, The normalized rise time of optic tract-evoked EPSCs is increased under CNQX, but the effect is again similar in the younger (filled bar) and older (open bar) cells. Diamonds indicate median values.
