Motor Cortex Computes Reaching Dynamics in Cartesian Reference Frames
Unsolved debate: M1 for muscle or movements?
Spatial representation of reaching dynamics
Spatial representation hypothesis
Model explains a variety of findings in M1 physiological and human psychophysical experiments
M1 properties
- Cosine tuning
- Position dependency of PDs
- Non-uniform distribution of PDs
- Coexisting multiple coorinate systems
Kinematics vs Dynamics
- Spatial properties of population vectors
- Temporal properties of population vectors
- Efficient computation of muscle tensions
Motor adaptation
- Neuronal activity change in constant load adaptation
- Neuronal activity change in viscous field adaptation
- Intrinsic-frame generalization in viscous field adaptation
- Extrinsic-frame generalization in visuomotor rotation adaptation
