AP Psych Ch 2 Review

Blindness could result from damage to which cortex and lobe of the brain?

• Visual cortex in the frontal lobe

• Visual cortex in the temporal lobe

• Sensory cortex in the parietal lobe

• Visual cortex in the occipital lobe

• Cerebral cortex in the occipital lobe

Paralysis of the left arm might be explained by a problem in the

• Motor cortex in the frontal lobe in the left hemisphere

• Motor cortex in the frontal lobe in the right hemisphere

• Sensorimotor cortex in the temporal lobe in the left hemisphere

• Motor cortex in the parietal lobe in the left hemisphere

• Motor cortex in the occipital lobe in the right hemisphere

Deafness can result from damage to the inner ear or damage to what area of the brain?

• Connections between the auditory nerve and the auditory cortex in the frontal lobe

• Connections between the auditory nerve and the auditory cortex in the temporal lobe

• Connections between the areas of the sensory cortex that receive messages from the ears and the auditory cortex

• Connections between the hypothalamus and the auditory cortex in the temporal lobe

• Connections between the left and right sensory areas of the cerebellum

Which chemicals pass across the synaptic gap and increase the possibility the next neurons in the chain will fire?

• Synaptic peptides

• Inhibitory neurotransmitters

• Adrenaline-type exciters

• Excitatory neurotransmitters

• Potassium and sodium

You eat some bad sushi and feel that you are slowly losing control over your muscles. The bacteria you ingested from the bad sushi most likely interferes with the use of:

• Serotonin

• Insulin

• Acetylcholine

• Thorazine

• Adrenaline

The three major categories researchers use to organize the entire brain are the:

• Old brain, new brain, and cerebral cortex

• Lower, middle, and upper brain

• Hindbrain, midbrain, and forebrain

• Brain stem, limbic system, and cerebral cortex

• Neurons, synapses, and cerebral cortex

A spinal reflex differs from a normal sensory and motor reaction in that:

• A spinal reflex occurs only in response to extremely stressful stimuli

• In a spinal reflex, the spine moves the muscles in response as soon as the sensory information reaches the spine while usually the impulse must reach the brain before a response

• In a normal sensory/motor reaction, the spine transmits the information through afferent nerve fibers, while reflex reactions are transmitted along special efferent nerves

• Spinal reflexes are part of the central nervous system response, while normal sensory/motor reactions are part of the peripheral nervous system

• Spinal reflexes occur only in animals because humans are born without instinctual responses

Antidepressant drugs like Prozac are often used to treat mood disorders. According to what you know about their functions, which neurotransmitter systems do these type of drugs try to affect?

• Serotonin

• Adrenaline

• Acetylcholine

• Endorphins

• Morphine

Which sentence most closely describes neural transmission?

• An electric charge is created in the neuron, the charge travels down the cell, and the chemicals are released that cross the synapse to the next cell

• A chemical change occurs within the cell, the change causes an electric charge to be produced, and the charge jumps the gap between the nerve cells

• The electric charge produced chemically inside a group of neurons causes chemical changes in surrounding cells

• Neurotransmitters produced in the hindbrain are transmitted to the forebrain, causing electric changes in the cerebral cortex

• Neural transmission is an electrochemical process both inside and outside the cell

Dr. Dahab, a brain researcher is investigating the connection between certain environmental stimuli and brain processes. Which types of brain scans is he most likely to use?

• MRI and CAT

• CAT and EKG

• PET and EEG

• EKG and CAT

• lesioning and MRI
