Polytrodes: high-density silicon electrode arrays for large-scale multiunit recording.

abstract：:High-frequency oscillatory activity (>200 Hz) termed "fast oscillations" (FO) have been recorded in the rodent somatosensory cortex and may reflect very rapid integration of vibrissal information in sensory cortex. Yet, while electrophysiological correlates suggest that FO is generated within intracortical networks, c...
