What is the primary role of the brain when executing a reach for a coffee cup, regarding reference frames?
Answer
To align different internal frames (e.g., retina, vestibular, body) to calculate the hand's position in the world frame
The brain must dynamically align data from various internal frames, such as the eye (retina) and the inner ear (vestibular), to determine the motor commands needed to place the hand accurately in the external world frame where the cup resides.
