Continual monitoring of reaching in rat using magnetic induction law.
A method enabling the continual monitoring of movement has been developed based on the law of magnetic induction. The method was concretely applied in the handedness model of the rat. A sensing loop was implanted under the forearm skin of a rat. Electric voltage was induced by the movement of the sensing loop in a DC magnetic field. This voltage is proportional to the movement velocity and its polarity to the direction. The continuous character of the movement record allows convenient analysis and a more exact correlation with the bioelectric concomitants of the movement.
