Mice lacking NMDA receptor function in the CA1 region of the hippocampus have impaired nonspatial memory. Exposure to an enriched environment, however, ameliorates these learning deficits and increases spine density in CA1. See pages 205 and 238.

    Treue and colleagues use electrophysiological recordings in monkeys and psychophysical experiments in humans to suggest that the shape of a population response in a motion sensitive region of the brain (area MT), rather than the peak of the response, determines motion perception.
