Context examples:
Researchers found a direct neural connection from the cerebellum to the ventral tegmental area (VTA) of the brain, which is an area long known to been involved in reward processing and encoding.

The study directly compared effects at two different brain locations – the subthalamic nucleus (STN) and ventral capsule (VC) – in the same patients.

Whereas responses in another brain area called the ventral striatum have been linked to reward processes, the dorsal striatum has been implicated in planning, motor (movement) processing, and habit learning.
