First Class Flashcards
What changes with development in age or ability appropriate paradigms?
behavioral and neural levels
Unlike other organs, __ __ have different outcomes, dependent on __ the lesion __
partial lesions
where; is
Define temporal lobe agnosia
the inability to recognize objectsd
define temporal lobe prosopagnosia
the inability to recognize faces
Define anterograde amnesia
no new memories
define retrograde amnesia
can’t remember old memories
What is the function of the cerebellum in memory and learning
helps learn motor skills
What role does the amygdala play in memory
emotional memory
What role does the hippocampus play in memory?
organizes sensory and cognitive information into a new memory
What role does the prefrontal cortex play in emotion?
controls expression of emotions
What emotions form in the hypothalamus and amygdala?
fear, anger, pleasure, love, etc.
Behavior is often learned by __ and __ or __ of others
rewards; punishments
responses
What are the receptors for somesthetic sensation?
touch, pressure, strech, temperature, and pain
Describe the gracile and cuneate fasciculi and spinothalamic tract pathways
ascending signals decussate, go to thalamus, to cortex
The somatosensory area is in the -_ __
postcentral gyrus
What are the lobes of the brain?
frontal, parietal, occipital, temporal, and insular
The fiber pathways formed by descending cortical fibers have three subdivisions, name them.
internal capsule
crus cerebri
pyramid
The descending cortical fibers are divided into three primary subdivisions, name them
corticopontine
corticobulbar
corticospinal
What are the five hippocampal regions?
dentate gyrus
CA3
CA1
subiculum
entorhinal cortex
What is an advantage of an fMRI
eliminates the need for exogenous agents, such as radioactive isotopes used in PET imaging
What does an fMRI study?
an indirect measure of brain activity
systems-level approach to study brain-behavior associations
Describe how DTI (Diffusion Tensor Imaging) works?
diffusion is a random molecular motion (Brownian motion)
can use this motion to determine the directionality of fiber tracts as indexed by motion of water molecules which is an indirect measure of myelin
Define a biomarker
an indicator of physiological, biochemical, or anatomic parameter
