right parietal lobe

An image projected to the left visual field of a split-brained person will be processed in the

right visual cortex

In right-handed individuals, which of the following abilities is predominantly a function of the right hemisphere of the brain?

spatial reasoning

Which part of the nervous system is most immediately activated by sudden fear?

sympathetic

The sequence of shifts in the electrical charge of a neuron is called

action potential

damage to the cerebellum would most likely result in which of the following problems

loss of motor coordination

People who have experienced severe damage to the frontal lobe of the brain seldom regain their ability to

make and carry out plans

Dopamine, norepinephrine, and acetylcholine are all

neurotransmitters that excite or inhibit a neural signal across a synapse

The hypothesis that intelligence is in part inherited is best supported by the fact that the IQ correlation for

pairs of identical twins is greater than for pairs of fraternal twins

The area of the brain stem that is important in controlling breathing is the

medulla

which of the following provides information regarding brain function by monitoring the brain at work through metabolism of glucose?

positron emission tomography (PET)

Which of the following would most likely result from an injury to the medulla?

A life-threatening disruption of heartbeat and breathing

An individual was admitted to the hospital after experiencing a mild tingling on the right side of the face and a sudden inability to speak. Using magnetic resonance imaging (MRI), a doctor would likely find

an abnormality in the brain tissue of the left hemisphere

which of the following is reduced during a flight-or-flight reaction

digestion

the depletion of which of the following neurotransmitters is most closely associated with the symptoms of alzheimer's disease?

Acetylcholine

In terms of the effect on the central nervous system, alcohol is most accurately classified as which of the following types of drug?

Depressant

A person with damage to Broca's area would most likely demonstrate which of the following symptoms?

E. Difficulty with speech production

A participant in a study of music perception listens to music with electrodes attached to her scalp while data are collected on the activity of her brain. This technique is called

Electroencephalography (EEG)

consistent with the concept of neural plasticity, neurons in mammals have been found to change the way they function as a result of repeated stimulation by doing which of the following?

Growing new dendritic spines

After an electrode implanted in a cat's brain stimulates the cat's amygdala, the cat will most likely do which of the following?

Immediately withdraw in fear

which of the following most accurately characterizes the role of the hypothalamus in the regulation of hunger?

It acts with the endocrine system to control hunger and satiety

which of the following is true of the reticular activating system?

It regulates levels of arousal.

It is well established that certain autonomic responses such as heart rate, perspiration, and respiration change under stress. In view of the fact that people generally have stronger autonomic responses when lying than when telling the truth, it follows that the polygraph would be a foolproof approach to lie detection. Which statement best explains why the polygraph is not more widely used in courtrooms and in testing of job applicants?

Physiological arousal is much the same for several emotions, so the polygraph cannot always reliably distinguish guilt from other reactions.

Which of the following occurs when a neuron is stimulated to its threshold?

The movements of sodium and potassium ions across the membrane creates an action potential.

A person will most likely develop aphasia as a result of damage to which of the following parts of the brain?

Wernicke's area

Electrically stimulating a rat's amygdala would most likely produce which of the following?

aggression

A polygraph machine is often called a "lie detector," although it does not detect lies. Instead, it responds to changes in

autonomic arousal

Painkilling substances produced by the brain are known as

b. endorphins

neurotransmitters are typically stored in which of the following parts of a neuron?

c) the terminal buttons

Which of the following allows the examination of living brain tissue visually without performing surgery?

computerized axial tomography

During a psychology experiment, a researcher uses a probe to lesion the ventromedial nucleus of a rat's hypothalamus. After the procedure the rat most likely will

eat more and gain weight

The brain scans of people with amnesia are most likely to show damage to the

hippocampus

When people consume large amounts of alcohol, they are often unable to recall what they did and said while they were drinking. This occurs because alcohol interferes with the brain's ability to form new memories in the

hippocampus

For most people, speech functions are primarily localized in the

left cerebral hemisphere

Damage to a small part of the occipital lobe would most likely result in a

visual deficit
