Abstract(in English) | Caminiti et al.in 1990 reported that the preferred direction of the motor cortical neurons in the monkey shifted with the static arm position.The present theoretical analysis shows that the shift of the preferred direction of both motor cortical neurons and the spinal motor neurons is necessary in order to code the motor command appropriately for various arm positions.Furthermore,the amount of the shift of the preferred direction is estimated from kinematics of a simplified two-joint model arm.The second issue of the present analysis is the corticospinal connectivity:it is shown that the preferred direction of the spinal motor neuron is determined by the corticospinal connectivity and the arm position. Interestingly,the results suggest that only the fundamental Fourier mode of the corticospinal connectivity contributes to the transformation of the motor command. |
