CORRECT ANSWERS SUCCESS PREP
GRADED A+
⩥ Postcentral Gyrus.
Answer: Primary somatosensory cortex.
⩥ Cingulate Gyrus.
Answer: Emotions, memory processes, behavioral regulation, part of the
limbic system.
⩥ Hippocampus.
Answer: Center for declarative memory.
⩥ Corpus callosum.
Answer: Axon fiber tract that connects the two hemispheres.
⩥ Cerebellum.
Answer: Collections of gray matter and white matter tracts, made of
spinocerebellum, cerebrocerebellum, and vestibulocerebellum.
,⩥ Cerebral cortex.
Answer: 16 billion neurons --> ~100 trillion synapses, involved in
higher-order processing.
⩥ Neocortex.
Answer: Neurons arranged in 6 layers based on type/density of neurons
and pattern/packing of dendrites, newest type of cortex.
⩥ Neocortex Layers.
Answer: Layer I: molecular, Layer II: external granular
(intra/corticocortical communication), Layer III: external pyramidal
(intracortical communication), Layer IV: internal granule (thalamic
input), Layer V: internal pyramid (output), Layer VI: fusiform/multiform
(output).
⩥ Allocortex.
Answer: Made of structures that have three layers, more layers = more
processing power (ex. hippocampus)
⩥ Pyramidal neurons.
Answer: Named for the shape of their cell bodies, large, often
glutaminergic neurons in the cortex.
⩥ Inhibitory neurons/Interneurons.
, Answer: Small, GABAergic neurons positioned to regulate the activity
of neighboring neurons in the cortex (80% excitatory, 20% inhibitory).
⩥ Spinocerebellum.
Answer: Includes vermis and anterior portion of the lateral lobe which
receives sensory info about current location of parts of body, plays a role
in anticipating subsequent movement; damage results in ataxia.
⩥ Cerebrocerebellum.
Answer: Interconnected with cerebral cortex, plays a role in planning
complex movements and cognition; damage results in movement
decomposition.
⩥ Vestibulocerebellum.
Answer: Composed of nodule and flocculus which are interconnected w/
the vestibular brainstem nuclei, helps the motor system to maintain
posture and guide eye movement; damage results in gaze deficits
⩥ Midbrain.
Answer: Mesencephalon; PAG for freezing, dorsal raphe nuclei for
serotonin, VTA for dopamine.
⩥ Pons.
