Exam 3: Section 4: Neuroscience and Behavior

Thinking, planning, and anticipating are activities associated with the frontal lobe.

The resting potential of a neuron is largely determined by the flow of potassium ions.

The somatic nervous system controls the voluntary movements of skeletal muscles.

The motor cortex is situated directly behind the somatosensory cortex.

fMRI can measure brain activity across briefer periods than PET.

Dendrites are parts of the neuron that receive information from other neurons.

It is possible to record the electrical activity from a single neuron.

The first neurons appeared in flatworms.

If you ever find yourself being chased by a crazed axe murderer, your parasympathetic nervous system will trigger heart rate increases, providing your muscles with more oxygen such that you can run faster and longer.

The reticular formation is important for regulating sleep, wakefulness, and arousal.

The ontogeny of the brain refers to how its development occurs within an individual.

The cerebellum coordinates heartbeat, blood circulation, and respiration.

An excess of glutamate activity can cause seizures.

Today, a neurologist who suspects a patient might have a brain tumor would probably order an fMRI scan to confirm its presence.

During prenatal development, the forebrain develops before the hindbrain.

Jenkins rapidly jerks his head to the sound of a car backfiring down the street, a behavior made possible by his tectum.

Both sodium and potassium ions flow across the plasma membrane of the neuron when it is at rest.

Researchers can demonstrate cause-and-effect relationships between brain function and behavior using TMS.

The human brain can be divided into four hemispheres and two lobes.

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