Relationship between input and output of cells in motor and somatosensory cortices of the chronic awake rat. A study using glass micropipettes.

abstract：:To investigate how the sensorimotor systems of eye and hand use position, velocity, and timing information of moving targets, we conducted a series of three experiments. Subjects performed combined eye-hand catch-up movements toward visual targets that moved with step-ramp-like velocity profiles. Visual feedback of th...
