What happens in your brain when you hit a golf ball?

Updated

When hitting a golf ball, the visual cortex locates the ball and target, the premotor cortex plans the swing, the motor cortex executes the movement, the cerebellum coordinates timing and balance, and the basal ganglia smooths the action.

Visual Cortex, Premotor Cortex, Basal Ganglia, Motor Cortex, Cerebellum, Somatosensory Cortex lit up on the Brain Atlas 3D brain: what happens in your brain when you hit a golf ball
Figure. The brain regions that light up when you hit a golf ball, in order: Visual Cortex (see the ball), then Premotor Cortex (plan the swing), then Basal Ganglia (initiate action), then Motor Cortex (execute swing), then Cerebellum (coordinate timing), then Somatosensory Cortex (feel the hit).

Brain regions that light up

OrderRegionWhat it does here
1Visual CortexPrimary visual cortex processes the ball's position and the target direction.
2Premotor CortexPremotor cortex prepares the sequence of muscle activations needed for the swing.
3Basal GangliaBasal ganglia select and initiate the motor program for the golf swing.
4Motor CortexMotor cortex sends commands to spinal cord to contract muscles in the correct order.
5CerebellumCerebellum fine-tunes the movement in real-time based on sensory feedback.
6Somatosensory CortexSomatosensory cortex processes touch and proprioception from the club and body.

1. Visual Cortex: see the ball

Step 1 of what happens in your brain when you hit a golf ball: Visual Cortex lit on the Brain Atlas 3D brain
Figure 1. Visual Cortex, see the ball: Primary visual cortex processes the ball's position and the target direction.

The visual cortex receives input from the eyes and identifies the ball and the target. It extracts edges, orientation, and motion to create a spatial map. This information guides the motor system's aim.

2. Premotor Cortex: plan the swing

The premotor cortex uses visual information to plan the complex sequence of movements. It integrates sensory input with learned motor patterns to set the swing's trajectory and force. This planning occurs before any overt movement.

3. Basal Ganglia: initiate action

Step 3 of what happens in your brain when you hit a golf ball: Visual Cortex, Premotor Cortex, Basal Ganglia lit on the Brain Atlas 3D brain
Figure 3. Basal Ganglia, initiate action: Basal ganglia select and initiate the motor program for the golf swing.

The basal ganglia evaluate competing motor plans and release the chosen program by disinhibiting the thalamus. This allows the motor cortex to execute the swing. For practiced golfers, this process becomes automatic.

4. Motor Cortex: execute swing

Step 4 of what happens in your brain when you hit a golf ball: Visual Cortex, Premotor Cortex, Basal Ganglia, Motor Cortex lit on the Brain Atlas 3D brain
Figure 4. Motor Cortex, execute swing: Motor cortex sends commands to spinal cord to contract muscles in the correct order.

The primary motor cortex activates upper motor neurons that project to the spinal cord. These signals travel down the corticospinal tract to coordinate muscle contractions in the arms, torso, and legs. The firing pattern determines the swing's speed and direction.

5. Cerebellum: coordinate timing

Step 5 of what happens in your brain when you hit a golf ball: Visual Cortex, Premotor Cortex, Basal Ganglia, Motor Cortex, Cerebellum lit on the Brain Atlas 3D brain
Figure 5. Cerebellum, coordinate timing: Cerebellum fine-tunes the movement in real-time based on sensory feedback.

The cerebellum compares intended movement with actual sensory feedback and corrects errors on the fly. It adjusts timing and force to maintain balance and accuracy. This role is crucial for the precise timing of the golf swing.

6. Somatosensory Cortex: feel the hit

Step 6 of what happens in your brain when you hit a golf ball: Visual Cortex, Premotor Cortex, Basal Ganglia, Motor Cortex, Cerebellum, Somatosensory Cortex lit on the Brain Atlas 3D brain
Figure 6. Somatosensory Cortex, feel the hit: Somatosensory cortex processes touch and proprioception from the club and body.

Receptors in muscles, joints, and skin send signals about body position, grip pressure, and impact. The somatosensory cortex integrates this feedback to update internal models of the movement. This helps refine future swings.

Good to know

  • Procedural memory for golf swings is stored in the basal ganglia and cerebellum, allowing skilled players to perform without conscious thought.
  • Dopamine release in the basal ganglia reinforces successful shots, contributing to motor learning.

Expert vs novice golfers

Expert golfers show less prefrontal cortex activation and more reliance on basal ganglia and cerebellum, reflecting automaticity. Novices engage premotor and prefrontal areas more heavily as they deliberately plan each movement. This shift is a hallmark of motor skill learning.

Test yourself

  1. Which brain region is primarily responsible for visually locating the golf ball and target?

  2. Which region is most critical for the fine timing and coordination of the golf swing?

  3. In expert golfers, which brain regions are more active compared to novices during a swing?

Simplified: many regions work together at once, and this shows the main players in the order they act.
