Final answer:
The main centers in learning new motor skills are the premotor cortex, supplemental motor area, basal ganglia, and frontal eye fields.
Step-by-step explanation:
The main centers in learning new motor skills are located in different parts of the brain. Two important regions that assist in planning and coordinating movements are the premotor cortex and the supplemental motor area. These areas are responsible for controlling core muscle movements, maintaining posture, and planning and coordinating movement, such as learned movements. Additionally, the basal ganglia and frontal eye fields play important roles in movement control and eye movement, respectively.
