Although significant progress has been made in understanding multisensory interactions at the behavioral level, their underlying neural mechanisms remain relatively poorly understood in cortical areas, particularly during the control of action. In recent experiments where animals reached to and actively maintained their arm position at multiple spatial locations while receiving either proprioceptive or visual-proprioceptive position feedback, multisensory interactions were shown to be associated with reduced spiking (i.e.

- Recent studies indicate that while both planning and execution affect endpoint variability in double-step reaching tasks, visual feedback noise significantly influences these movements.
- Twelve subjects were tested on reaching with both dominant and non-dominant arms to targets in 3D space, with results showing that visual feedback led to smaller and more precise movement patterns.
- The dominant arm exhibited a greater reduction in variability due to visual feedback, implying that it utilizes visual information more effectively for controlling reaching movements compared to the non-dominant arm.
