Define Primary motor cortex corticospinal interneuron A

Primary motor cortex (M1) corticospinal interneuron A that produces action potentials during movements of the big toe of the left foot in right-handed Patient X who has a complete transection of the corpus callosum.

  A.  In Patient X, the cell body of interneuron A is located in between the central sulcus of the right cerebral cortex and the right eye.

  B.  The axon terminals of interneuron A are located on the left side of Patient X's spinal cord.

  C.  Interneuron A will increase its action potential firing rate after Patient X reads the statement "Wiggle the big toe of your left foot" presented in Patient X's right visual field.
