Misc. Flashcards
function of limbic association area
behavior, emotions, motivation
parieto-occipitotemporal assocation area
analysis of spatial coordinates of body (neglect syndrome), area for language comprehension (reading), area for naming objects, area for recognition of faces/complex forms
wernicke’s
general interpretation area (auditory, visual, somatic)
angular gyrus
higher order visual signal processing
prosopagnosia
impaired recognition of familiar faces
after identification of an object/face projections from the ___________ allow the person to gage the emotional significance of what has been identified
fusiform gyrus to the amygdala
capgras syndrome
subject thinks close relatives are imposters due to lack of emotion evoked by visually seeing them (occurs only when visualizing them)
ventralmedial frontal area
emotions and its underlying neural machinery participate in decision making within the social domain
ventromedial frontal areas connected with…
subcortical nuclei like the amygdala and hypothalamus (involved with basic biologic regulation, emotional processing, social cognition and behavior)
low concentration of serotonin S2 receptors in ventromedial frontal area is association with…
behavior that is aggressive and socially uncooperative
prefrontal association area function
judgment, planning for future, holding/organizing events from memory for prospective action and working memory
anterior commissure
bidirectional communication between anterior portions of the temporal lobe (amygdala)
amygdala
emotional response transfer
split brain was originally done to prevent
spread of seizure activity from one hemisphere to the other
left hemisphere usually matches based on
function
right hemisphere usually matches based on
appearance
allocortex is made up of
archicortex and paleocortex
allocortex includes
hippocampus, dentate gyrus and subiculum
hippocampus has 3 layers…
I, V, VI
dentate gyrus has 3 layers…
I, IV, VI
subiculum is part of
parahippocampal gyrus
hippocampal formation receives input from the entorhinal cortex of the parahippocampal gyrus through
perforant and alveolar pathway
hippocampal formation plays an important role in
declarative memory
parahippocampal regions have bidirectional connections with…
cerebral cortex (encode specific memory cues - semantic)
evidence from place cells offers strong support for the hippocampus’ involvement in…
spatial mapping
positive memory associated with
facilitation
negative memory associated with
habituation
hyperthymestic syndrome
person has total recall of all events they have experienced. LARGE CAUDATE NUCLEUS
habitutation
decrease in response to repeat benign stimulus
sensitization
overrides effects of habituation
Zeta inhibitory peptide blocks
PKM zeta
without PKM zeta …
cannot retain long term memory
reticular excitatory area
control of the overall level of excitation of brain
