Neural activity related to unrestrained movement through space was studied in rat sensorimotor and posterior parietal cortices during performance of an eight-arm, radial maze task. Nearly half of the cells exhibited movement-related activity that discriminated among three basic modes of locomotion: left turns, right turns, and forward motion. Correlates(More)
The influence of behavioral state on the induction of long-term enhancement (LTE) of hippocampal synapses was studied in chronically prepared animals. Perforant path evoked field potentials and EEG were recorded from fascia dentata during slow-wave sleep (SWS) and waking. LTE was strongly suppressed during SWS, suggesting that hippocampal information(More)
