Exam 3: Section 4: Neuroscience and Behavior

Relative to other body parts, a good deal of space in the somatosensory cortex is devoted to the tongue.

One function of the parasympathetic nervous system is to relax the bladder.

The spinal cord is continuous with the hindbrain.

Low levels of acetylcholine and dopamine have been implicated in depression.

The activation of mirror neurons is vital in allowing us to learn how to imitate the subtle muscle movements of a complex motor skill.

At rest, the neuron does not carry an electrical charge.

A split-brain patient can verbalize a description of something in the right field of vision but cannot point to the object with the left hand.

PET scans and fMRI scans both measure brain function.

A heritability coefficient of 1.0 for a trait indicates that the environment cannot explain any of the observed variability in that trait.

Hubel and Wiesel mapped the visual cortex using fMRI.

A mouse has a larger cerebral cortex than a snake.

The terminal branch is the space between the axon terminal of one neuron and the dendrites or cell body of another neuron.

Dizygotic twins result when a single fertilized egg splits into two.

Given that the heritability for Trait Q in the population of people with Gene Z is .80, a person with Gene Z has an 80 percent chance of having Trait Q.

The hippocampus is shaped like a sea horse.

The environment may determine whether or not a gene is expressed.

Purkinje cells are interneurons that carry information from the cerebellum to the rest of the central nervous system.

A person with damage to Broca's area will have problems understanding language.

Damage higher on the spinal cord usually results in more severe impairment.

The frontal lobe processes auditory information into meaningful units.
