abstract：:1. Voltage-clamp experiments were used to study N-methyl-D-aspartic acid (NMDA) receptor antagonists applied by fast perfusion to mouse hippocampal neurons in dissociated culture. 2. Preincubation with the NMDA antagonists zinc (3-30 microM) and magnesium (30-300 microM) reduced subsequent responses to 100 microM NMDA...
