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

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
• 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 left and right sensory areas of the cerebellum 
• connections between the hypothalamus and the auditory cortex in the temporal lobe 

According to the theory of evolution, why might we call some parts of the brain the old brain and some parts the new brain? 

• The old brain developed first, according to evolution
• Old brain parts are what exist in very young children, and the new brain develops later 
• The old brain becomes more active as we get older 
• The old brain is most affected by age deterioration while the new brain remains unaffected 

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

• synaptic peptides
• potassium and sodium 
• inhibitory neurotransmitters. 
• Excitatory neurotransmitters 

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

• old brain, new brain, cerebral brain
• lower brain, middle brain, upper brain
• hindbrain, midbrain, forebrain
• brain stem, limbic system, 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 reflect, the spine moves the muscles as soon as the sensory information reaches the spine. 
• spinal reflexes are part of the central nervous system response, not the peripheral 
• 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 function, which neurotransmitter system do these types of drugs try to affect? 

• serotonin
• adrenaline
• acetylcholine
• endorphins

A neuron without terminal buttons would be unable to

• receive information from neighboring neurons
• generate an action potential
• direct the synthesis of neurotransmitters
• secrete neurotransmitters to post synaptic neurons 

Paul Broca found that the loss of the ability to speak intelligibly is associated with damage  to a region of the brain in the  

• left frontal lobe
• thalamus
• left temporal lobe
• right parietal lobe
