Syllable-frequency effects in visual word recognition: evidence from ERPs.

abstract：:Delayed neuronal death induced by transient forebrain ischemia in the rat hippocampus is preceded by a prominent microglial reaction which begins within minutes after the ischemic injury. In the present study we have examined the effect of the non-competitive N-methyl-D-aspartate (NMDA) receptor antagonist MK-801 on m...
