Exam 3: Section 4: Neuroscience and Behavior

Plasticity refers to cortex adaptation to changes in sensory inputs.

Neurons can exist in simple organisms without central nervous systems.

Transcranial magnetic stimulation (TMS) uses a magnetic pulse to temporarily "shut off" selected brain regions.

If you continually practice a skill involving precise, coordinated movements of the fingers, the areas associated with your fingers in the sensory and motor cortices will increase in size and/or function.

The two major subdivisions of the peripheral nervous system are sympathetic and parasympathetic.

There are more neurons in the brain than glial cells.

An EEG requires electrodes be implanted inside the brain.

Electrochemical conduction refers to the movement of an electric signal within a neuron.

Lesions to some areas of the hypothalamus may result in a loss of interest in food.

Monozygotic twins share 100 percent of their genes.

People with damaged lumbar nerves probably cannot move their arms.

During the refractory period, a chemical pump moves sodium into the cell and potassium out of the cell.

Electrically stimulating a certain region of the hypothalamus produces feelings of intense pleasure.

The striatum is a part of the basal ganglia involved in movement.

Heritability is meaningful only in the environmental context that it was computed.

Severing the connections between the reticular formation and the rest of the brain may result in an irreversible coma.

Interneurons carry signals from the spinal cord to the muscles to activate movement.

The hippocampus is critical for the formation of new memories.

The unfortunate case of Phineas Gage allowed researchers to learn how the frontal lobe interacts with the amygdala to affect emotion regulation.

The frontal lobe contains the motor cortex.
