Sensory Systems
Motor Systems and Organization
100

This defining property sets sensory receptors apart from other cells.

What is converting energy into nerve impulses?

100

Evidence suggests the primary motor cortex is organized on the basis of this.

What are specific movements?

200

Each sensory system employs cortical regions that contain this kind of map of the sensory world.

What are multiple specialized maps?

200

Movement sequences are organized primarily by neurons in this cortical area.

What is the premotor cortex?

300

The axons of these retinal cells bundle together to form the optic nerve.

What are retinal ganglion cells?

300

These neurons may provide a neurobiological basis for imitation and empathy.

What are mirror neurons and social awareness?

400

A patient who cannot locate limb position without looking has lost this sense.

What is proprioception?

400

Difficulty with balance, posture, and coordination most strongly suggests a lesion here.

What are the brainstem motor areas?

500

After a traumatic brain injury, a patient cannot perceive flavors. Damage here is the likely cause.

What is the orbitofrontal cortex?

500

The basal ganglia receive major inputs from these two sources.

What are the neocortex and the substantia nigra?
