Figure 4.
A. IR-DIC (top panel) and biocytin (lower panel) images of a dysmorphic cytomegalic pyramidal neuron recorded in a CD Type IIa case. B. PGA from the cytomegalic neuron shown in (A). Downward deflections at Vhold=−50 mV are spontaneous glutamatergic synaptic currents. C. Autocorrelogram of PGA shown in (B). D. At −80 mV this neuron displayed small-amplitude PGA that was blocked after addition of BIC. The remaining events were glutamatergic as they were completely blocked by application of non-NMDA (CNQX) and NMDA (APV) receptor antagonists.
