pain receptors and what irritates (activates) them

Neurotransmitters related to pain

The gate theory (or gate control theory) of pain
 and things that influence the gate

Chapter 9 Sleep and Biorhythms

What recordings are a typical part of the polysomnogram used in sleep research?

How does the EEG change as we go from wakefulness to relaxation to falling asleep and then going deeper and deeper into sleep?

How do we move through the stages of sleep during a typical night of sleep?

How is NREM sleep different from REM sleep?

What parts of 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



Night terrors

Sleep apnea

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 the difference between a circadian rhythm, a circalunar rhythm and a circaannual rhythm?

What do we mean when we say biorhythms are "endogenous"?

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?

Describe at least 2 ways that you can “encourage” the resetting of your biological clock if, for example, you were going to London?

Chapter 14

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 researchers?

What kinds of results from split brain research support the notion of lateralization? 

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?
