Exam 46: The Mammalian Nervous System: Structure and Higher Functions

Refer to the figure below showing how on-center and off-center ganglion cells of the retina encode patterns of contrast between light and dark.Choose the answer option that includes the correct patterns of stimulation that match the activity of on-center and off-center ganglion cells, starting with Row 1 (A) and ending with Row 4 (D).

Which of the following would not result from stimulating sympathetic nerves?

Refer to the figure. What would be the effect on digestive activities of stimulating the division labeled 2?

In the case of autonomic innervation of most organs, the two divisions of the autonomic nervous system

If a person is unable to form a memory of people, places, events, and things, he has lost the ability to form_______ memories.

Conscious afferents are part of the _______ nervous system and carry information from _______.

Refer to the figure. A football player sustains an injury to his head and as a result suffers from an agnosia that leaves him unable to recognize faces.First define agnosia.Then select the number that represents the region of his brain that is likely impaired.Additionally, identify the region.

Damage to the temporal lobe of the cerebrum results in conditions called _______ in which an individual is aware of an object but cannot identify it.

Refer to the figure. The figure shows how on-center and off-center ganglion cells of the retina encode patterns of contrast between light and dark.Evaluate the following statement: Row B represents what happens when a large spot of light covers the receptive field.

The entire body surface can be mapped onto the primary somatosensory cortex, based on the density of mechanoreceptors and the ability to make fine discriminations in touch in a given area.Which of the following would require the smallest amount of cortical representation in comparison to its surface area?

Bipolar cells receive input from a large number of photoreceptors, and individual retinal ganglion cells collect information from a number of bipolar cells.The ability of individual ganglion cells to receive inputs from multiple neurons is called
