Question

blake is clumsy because their never fibers are bad at sending signals to the brain about when they move a body part (a.k.a. proprioception). which of blakes nerve fibers is impaired?
group a alpha
group a beta
group a delta
group b
group c
blake is clumsy also because their brain has a hard time stitching together where something is visually, with where sounds come from, and with where their body is in space (somatosensation)
which of blakes brain areas is impaired?
primary motor cortex (m1)
primary somatosensory cortex (s1)
posterior parietal cortex (ppc)
superior temporal cortex (a1)
ventral temporal cortex (vtc)

Explanation:

• For the first question: Group A alpha fibers are involved in proprioception (sending signals about body - part movement to the brain).
• For the second question: The Posterior Parietal Cortex (PPC) integrates visual, auditory, and somatosensory information (stitching together where something is visually, where sounds come from, and where the body is in space).

Answer:

• First question: group A alpha
• Second question: Posterior Parietal Cortex (PPC)
