GUIDE FOR EXAM 3
A NOTE ABOUT THE STUDY GUIDE:
Be aware that although the study guide helps review concepts, it is not
all inclusive and other items emphasized in class and the readings and
NOT in the study guide may appear on the exam. The study guide is therefore
a good place to BEGIN exam preparation.
CONTROL OF BRAIN AND BEHAVIOR
Review the study guide and Chapters
9, 10, 11, 12, and 15. Lots of info is presented here!
Study your notes and all the
relevant chapters. Know the meaning of all words in the boxes, and italicized.
There will be more DEFINITIONS on this second exam
Think about what you have learned,
talk about it in a study group.
is the importance of the secretory hypothalamus? how does it interact does
with the pituitary? What are the divisions of the autonomic nervous systems?
when are they active? What transmitters are important in the ANS? What
are the diffuse modulatory systems? (DMS). What behaviors are they associated
with and where do they originate? How do LSD, cocaine, and amphetamines
affect the nervous system? How do drugs to treat depression affect NE and
serotonin? What are the catecholamines and what kinds of drugs affect their
List all the senses (and their
respective sensory cells) discussed in class and in the text. For each
sense (except chemical covered last exam)
know the structure of all the
be able to explain how each
sensory cell senses and transduces its modality into a RECEPTOR POTENTIAL.
Understand how they are routed
to the CNS and what synapses are made with second order neurons if appropriate
it may be useful to make a table
contrasting sensory cell structure and transduction
be able to delineate the pathways
to the "higher" brain centers that routes each sense to its destination
from the peripheral site of signal reception. be able to identify the different
nuclei etc., where the tracts synapse with target cells in the CNS. again,
a table or flow chart may be useful here.
Know the cortical organization,
if this was covered in class
Know the meaning of all words
in the boxes, and in bold. AND AT THE END OF THE CHAPTER.
For each sense, what aspects
of stimulus encoding provide evidence
of parallel processing
of organized mapping of stimuli
Is neural space always a faithful
representation of the sensory field? explain with examples.
12: know the different receptor subtypes responsible for
encoding somatic sensation. contrast the Pacinian corpuscle with the Meissner
corpuscle. what is the role of the capsule in Pacinian corpuscle function?
why are proprioreceptors important? contrast warm and cold receptors. How
are primary afferents classified? which afferents convey which sense? what
are the ascending pathways for somatic sensation? how is facial somatic
sensation conveyed to the brain? what is somatopy? what is the sensory
homunculus? contrast pain and nociception. how is pain regulated? what
is the role of endorphins in pain regulation?
11: understand the structure of the ear and the cochlea,
and how their structure assists their function. understand the tonotopic
organization of the cochlea and of the auditory cortex. how are frequency
and stimulus intensity encoded? what are the subdivisions of the vestibular
system? how do hair cells work? what are otolith organs? what is a macula?
what are semicircular canals? crista? ampulla?
9: what are the main parts of the eye? how do lenses correct
your vision? understand the structure of the retina and how its laminar
organization assists its function. understand color vision. how does the
concept of center-surround apply to bipolar cells? to ganglion cells? contrast
M-type and P-type ganglion cells.
10: REVIEW CONCEPTS THROUGH APRIL 11 LECTURE. understand
how the pathways encoding the right and left visual fields are mapped onto
the LGN and striate cortex. where are pathways separate? where do they
converge? how was radioactive labeling used to study these pathways? understand
the retinotopicity of the LGN and the striate cortex. how are the LGN and
striate cortex organized? why are the LCN and striate cortex also said
to have a laminar organization?
