Mr. Smith has difficulty seeing the left side of his visual field and has lost control of the right side of his body. C. Mr. Smith has difficulty seeing the right side of his visual field and has lost control of the right side of his body. D.

You awaken with a start and realize that all the cafeteria sounds have just “come back.” While you were dozing, this auditory input was blocked from reaching your auditory cortex bya. the temporal lobe.b. the thalamus.c. the reticular activating system.d. the medulla oblongata.e. the vestibulocochlear nerve.
- Tristan accidentally touches a hot propane torch. He immediately withdraws his hand and then exclaims “ouch!” Why did Tristan exclaim “ouch!” after he had withdrawn his hand from the hot coffee? Select one: a. The threshold of the sensory receptor was exceeded and an action potential to the brain could not be triggered. b. The neural processing is faster through the spinal cord than the processing involving the brain. c. The sensory receptors in the fingers were damaged by the hot torch and were not able to send a fast signal to the brain. d. The hot torch triggered too many receptors and resulted in an excessive number of nerve impulses travelling to the brain. The brain was not able to process all the signals fast enough.Which is true regarding somatotopic organization? Select one: a. Certain areas of the body have much higher representation in the primary somatosensory cortex than other areas, and these regions will have finer tactile discrimination. b. The representation of a given area of the body in the primary somatosensory cortex is directly proportional to the size of that body area (e.g., the right index finger has less representation than the right thigh). c. The receptive fields for somatosensory neurons are circular and relatively consistent in size across areas of the body, but areas of the body with the finest tactile discrimination have many more neurons representing them in the primary somatosensory cortex. d. There is equal representation of all areas of the body in the primary somatosensory cortexIf a pedestrian runs in front of your car and your eyes dart to the left to avoid hitting him, what region of the brain is critical for separating the movement of the pedestrian from the movement of your eyes?
