Electrical stimulation of the basal nuclei and cerebellum can produce skeletal movements. Describe the pathways by which these brain regions control motor activity.

What structural features of the primary motor cortex somatotopic map reflect the general principle of physiology that structure is a determinantand has coevolved function?

How is the information determined by the motor program?

The shape of the cell bodies of upper and lower motor neurons are structurally classified as blank and blank, respectively

Motor neurons have many functions, which include to: Carry a nerve impulse away from the CNS Send sensory information to the CNS Detect a stimulus from a sensory receptor Transmit a nerve impulse to an interneuron Take an impulse from an effector to a sensory neuron

Consider three alpha-motor neurons of different sizes: small, medium and large. All three neurons receive input from the same excitatory interneuron. When the interneuron fires action potentials at low frequency, only one alpha motor neuron fires action potentials. As the action potential frequency of the interneuron increases, two alpha-motor neurons are recruited, and at maximum frequency, all three are recruited. In what order would the three alpha-motor neurons have been recruited? Large first, then medium, then small. Small first, then medium, then large. Medium first, then small, then large. Medium first, then large, then small.

Multi-cell recordings from the human motor cortex can be used to guide a robotic arm. Discuss BCI and action control: a) How the woman controls the robotic arm b) She has been paralyzed for over 20 years, but this BCI system still works for her. What does that mean? c) What kinds of information do motor neurons code?
