When we are able to prepare in advance of a movement, the subsequent movements generally get better. Motor cortical activity during preparation has been studied extensively, showing clear relationships between the neural population state achieved during preparation and the parameters of the subsequent self-initiated movement. However, movements are often triggered or corrected based on disturbances to the body or environment. Since such disturbances can often be predicted based on experience or other streams of sensory input, we reasoned that sensory expectations should also shape preparatory
