Abstract :
Descending signals in the rat cervical spinal cord (C5/C6) were recorded using a 15-channel microelectrode array during reach-to-grasp task. Signals were segregated into frequency bands to investigate the frequency content. Population activity was obtained by band-pass filtering the signals between 300 Hz-3 kHz. Local field potentials (LFPs) were analyzed between 0-13 Hz, 13-30 Hz, and 30-100 Hz. The population activity and the LFPs in 0-13 Hz were able to predict the behavior onset. Spectrograms indicated a clear difference between the quiet and behavioral state of the animal.
