PSYB64 MIDTERM 1 TEST
QUESTIONS AND ACTUAL ANSWERS
2025-2026 UPDATED.
Jangle fallacy - Answer Multiple terms used for the same structure
Jingle fallacy - Answer The same term used for different structure
Central Nervous system - Answer consists of the brain and spinal cord
Peripheral nervous system - Answer contains all the nerves that exit the brain and spinal
cord, carrying sensory and motor messages to and from other parts of the body
Injury to CNS vs PNS - Answer damage to CNS is permanent, while PNS can have recovery
The final exam for PSYB64 in the 2024 winter term is ________. It is worth a total of__________
of my grade. Part 3 of the final exam tests part 3 of the course and it amounts to ________ of
my final grade. The midterm for parts 1 and 2 are each worth _____ of my final grade.
a) cumulative; 60%; 10%; 40%; 20%
b) cumulative; 40%; 5%; 30%; 30%
c) not cumulative; 20%; 30%; 20%; 10%
d) not cumulative; 60%; 10%; 40%; 20% - Answer b
CT (Computerized tomography) - Answer Measures the density of the tissue being studied.
Dense material = white, Less dense = black. White matter is high in fat, so it appears slightly
darker than cellular gray matter.
Low cost and excellent structural information, but cannot distinguish between living and dead
brain. No information about activity level.
Useful for skull fracture, calcified lesion, claustrophobic/obese patient, metallic appliances or
fragments in patients.
MRI (Magnetic Resonance Imaging) - Answer Uses magnetic and radio signals, safer than CT.
High resolution structural images, but high cost, poor temporal resolution, and loud noises.
,Useful in subtle area of tumor, infarct, demyelination, and when anatomical detail is needed.
fMRI (functional MRI) - Answer able to correlate brain activity with stimulus, emotional
state, or task performance; can distinguish between blood carrying rich supply of oxygen and
blood that isn't.
But poor temporal resolution and high cost.
EEG (electroencephalogram) - Answer record brain's electrical activity by placing electrodes
on the scalp. Measures postsynaptic potentials from populations of neurons, and does not
measure action potential.
superb temporal resolution, but poor spatial resolution.
ERPs (Event-related potentials) - Answer able to correlate the timing of activity of cortical
neurons recording via scalp electrodes with stimuli.
High temporal resolution, but poor spatial resolution
Subtraction contrast - Answer technique in fMRI that can tell us where in the brain is more
active and where is relatively less. Using acitivtiy in condition A minus activity in condition B will
equal to region with more/less activity in condition A.
EEG vs. ERPs - Answer EEG is a continuous measure of brain activity, while ERPs measure
brain activities in face of a stimulus which is presented repeatedly then the brain activities are
averaged.
rostral - Answer near head
caudal - Answer near tail
ventral - Answer towards belly
dorsal - Answer towards back
anterior - Answer to the front
posterior - Answer to the back
, superior - Answer to the top
inferior - Answer to the bottom
neuraxis - Answer an imaginary line that runs along the length of the CNS
midline - Answer An imaginary vertical line that divides the body into equal halves
ipsilateral - Answer on the same side of the midline
Contralateral - Answer on the opposite side of the body
medial - Answer close to midline
lateral - Answer away from midline
proximal - Answer close to enter
distal - Answer far away from center
meninges - Answer three layers of membrane that cover the CNS, from outermost to
innermost: dura meter, arachnoid layer, pia mater
subarachnoid space - Answer space between arachnoid mater and pia mater that contains
CSF
Cerebrospinal fluid (CSF) - Answer plasma-like fluid circulates through the ventricles of the
brain, cerebral aqueduct, central canal of the spinal cord, and the subarachnoid space
what produces CSF? - Answer choroids plexus (ie. the lining of the ventricles) that converts
material from the bloody supply into CSF
CSF circulation - Answer 1. Choroid plexus produces CSF.
2. CSF flows through third and fourth ventricles into the central canal
3. CSF exits the subarachnoid space.
