Conscious control of our body's functions is handled by the __________ nervous system,while unconscious (unaware)body functions are controlled by the __________ nervous system.

Evolutionarily speaking,which part of the brain is the newest? In other words,which part of the brain appears to have developed the most recently?

The basal ganglia are a set of interconnected structures that contain all but which of the following?

If a neuron's dendrites receive almost enough electrochemical stimulation to exceed that neuron's threshold,then a partial action potential will be generated.

According to researcher Paul MacLean,the human brain is best thought of as being divided into __________ regions.

Which parts of the body get the most "space" and attention in the primary somatosensory cortex of the parietal lobe of the cerebral cortex?

Giselle came home from her junior prom in absolute agony.She saw her date - her boyfriend and the love of her life - dancing with her mortal enemy.She felt like they were dancing WAY too close to each other,and she broke up with her boyfriend in a fit of anger.Now she was an emotional wreck.She needed her mother and sister to sit with her and console her for several hours before she was finally calm enough to go to sleep.Neurologically speaking,which part of her brain was probably not overactivated during this very difficult time?

The telephone wires that lead from your home to the homes of friend,relatives,and even strangers are all covered by a thick,protective tube that insulates them from damage.This tube helps eliminate damage from things like water,birds' feet,bugs,dirt,weather,tree branches,and other potential interruptions in communication.In the human neuron,the same sort of protection is provided by the __________.

Who is most likely to have some amount of language functioning controlled by both hemispheres of their cerebrum?

That which you sense with your eyes is processed in the occipital lobe of your cerebral cortex.It is interesting,however,that both halves (hemispheres)of the occipital lobe help process visual information.In fact,that which you "sense" with your right eye is processed in the left hemisphere,and that which you "sense" with your left eye is processed in the right hemisphere.This is a concept called __________ connectivity.

As you watch your favorite team play football on a brisk Sunday afternoon,you start thinking back to your recent lecture on neuropsychology.You watch as the quarterback sends a blistering pass to the wide receiver,who takes the ball and heads upfield with it.If you were to relate this scene to a neuron's activities,which football player would represent the postsynaptic neuron?

What is meant by the statement "A major characteristic of the human brain is adaptability?"

What is meant by the statement "A major characteristic of the human brain is sophistication?"

Think of the human neuron as being analogous to your home computer.The computer has many parts.It has a printer,a monitor,a mouse,a video card,and many other components.Which part of the "neuron" would be similar to a computer's central processing unit (CPU)?

In addition to providing structural support and protection for the axon of a neuron,what other very important function is served by the presence of a myelin sheath?

The human central nervous system contains which of the following structures?

How would you most accurately characterize the neural impulse that travels from one neuron to another across a synapse?

Reuptake of the neurotransmitter __________ is thought to be a main culprit in the development of depressive symptoms.

What is the glue that holds neurons together?
