Generation of a Voluntary Movement
Outside of reflexive movements, voluntary movements are going to be the basis of how the brain controls the body in sport
This is a highly complex process, but here are 4 steps that occur to generate all voluntary movements⬇️⬇️
1) The cerebellum collects information to predict the sensory consequence of motor actions & send error signals. It then generates an internal model of what the movement should look like (The cerebellums main function is coordinating movement)
2) The parietal lobe then compares the internal model from the cerebellum with sensory feedback from the body in order to make necessary changes to the internal model for action (The parietal lobe’s function is processing somatosensory information from the body)
3) The basal ganglia helps in coordinating movement by estimating the “cost-to-go” during the execution of the movement. This helps provide optimal control of the motor task (The basal ganglia’s main function is modulating movement)
4) The motor cortex areas in the frontal lobe transform this information into a motor output and goal-directed movement. Again, actual movement is far more complex, with many other structures and functions being involved but this provides a good basis of producing movement
For example, all these steps occur during the likes of a play like a Derrick Rose layup
The cerebellum, somatosensory cortex in the parietal lobe, basal ganglia, and motor cortex all communicate in an instant to create this finish at the rim against defenders
