The characteristics
of light waves
The parts of the eye
and how light gets to the receptors
The structure of the
retina
the receptor sites on rods and cones and the
light sensitive pigments they contain
The differences
between rods and cones
theories of color
vision and where each seems to apply
the basis for color
blindness/deficiency
The route taken by
visual messages through brain
relationship between oour right and left visual
fields and primary visual cortex
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
- cortical blindness
Dorsal
stream/parietal damage
Ventral stream/Inferior temporal
cortex/fusiform gyrus damaged
visual or object agnosia
prosopagnosia
Parts of ear and how
they transmit sound input
Structure of cochlea
and the hair cells in the organ of Corti on the basilar
membrane
relationship to the cochlea to pitch
von Bekesy's research on the fluid movement in
the cochlea and the peak of the traveling wave
What triggers the
electrical responses of the hair cells
using what is known about the cochlea to create
cochlear implant
Stops along the
auditory pathway to cortex (superior olives, inferior
colliculus, medial geniculate of thalamus)
How having 2 ears
helps in sound localization
theories of pitch perception
Organization of
auditory cortex (tonotopic)
2 types of deafness
What are the 2 main theories about why
we sleep?
What is a free-running rhythm? How do
they differ in characteristics from the rhythms seen under
normal conditions?
What is a zeitgeber?
Blindness effects on circadian rhythms
How does SCN get input about the
day/night cycle?
What is the research evidence about the
location of the circadian biological clock?
That is the role of the pineal gland in
sleep?
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
Which is an easier adjustment for your SCN - phase-delay or phase advance?
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
parts of the brain are involved in sleep?
What are the characteristics of each of
these sleep disorders:
REM behavior disorder
Narcolepsy
Sleep-walking
Night terrors
Sleep
apnea
What are some of the types/causes of
insomnia?
