the brain are involved in maintaining wakefulness/alertness?
What neurotransmitters are involved in keeping you awake?
What neurotransmitters are involved in
making you sleepy?
Why, specifically does caffeine keep you awake and do some anti-histamines make you sleepy?
What are the characteristics of each of these sleep disorders:
REM behavior disorder
What are some of the types of insomnia and possible physiological correlates (e.g. why might someone have “onset insomnia”?)
What are the 2 main theories about why we sleep?
2 theories about REM sleep?
What is a free-running rhythm? How do they differ in characteristics from the rhythms seen under normal conditions?
What is a zeitgeber?
What is the research evidence about the location of the circadian biological clock?
Describe 2 biological mechanisms by which the functioning of this biological clock may make us sleepy?
What stimulus is most effective in resetting the biological clock?
least 2 ways that you can “encourage” the resetting of your
biological clock if, for example, you were going to

What is the difference between the “dorsal stream” and the “ventral stream”?
Damage to different parts of the visual pathways can lead to different losses of visual ability? What happens in each of these cases?
Primary visual cortex totally damaged
Inferior temporal cortex/fusiform gyrus damaged
Middle temporal cortex damaged

What is meant by lateralization of function?
the anatomy and function of the corpus callosum
review the relationship between the right & left visual fields and the 2 hemispheres
What is a seizure? When do seizures qualify as epilepsy?
2 main types or categories of epilepsy and their causes
why cutting the corpus callosum would be expected to limit the spread of focal seizures
How are split brain patients tested by

What functions each hemisphere is dominant for (make a detailed list for each)
Give an example or 2 of competition between the hemispheres after surgery
What is the relationship between handedness and lateralization?
