Suppose a researcher interested in measuring body posture instructs participants to maintain existing body posture for the week prior to baseline testing and intervention.

(A) The neurosurgeon Wilder Penfield was an important pioneer in mapping the organization of the cortex. Briefly describe the mapping procedure he used. (2 pts) (B) Penfield discovered that there is a “topographic” representation of the body in somatosensory and motor cortex. Explain what this means. (3 pts) (C) Also working in somatosensory cortex, Vernon Mountcastle used single neuron microelectrode recordings to discover a fundamental organizing principle of the cortex. Describe this organization (i.e. his finding). (2 pts) (D) David Hubel and Torsten Wiesel discovered that neurons in primary visual cortex are “orientation selective”. Explain what this means. (3 pts)
