Memantine Effects on Electroencephalographic Measures of Putative Excitatory/Inhibitory Balance in Schizophrenia.
Summary
This application seeks to determine if neurophysiological metrics of memantine (MEM)-enhanced early auditory information processing (EAIP) in schizophrenia (SZ) mediate gains in auditory processing fidelity (APF) and auditory learning.
