Final Exam Review Guide Flashcards
Major function/ area: frontal lobe
complex socioemotional
planning, organization, higher order functioning
Major function/ area: occipital lobe
low-level vision
Major function/ area: temporal lobe
basic socioemotional, language, audition
Major function/ area: parietal lobe
concerned with reception and correlation of sensory info
Major function/ area: cerebellum
finesse movements
Major function/ area: thalamus
relay station of the brain
Major function/ area: amygdala
experience of emotion
explicit/ declarative memory
memories that can be consciously recalled
semantic memory
memory for facts
episodic memory
memory of autobiographical events
learning/ memory process
encoding, consolidation, recall
agnosia
object recognition problem
prosopagnosia
facial recognition problem
aphasia
loss of ability to understand (Wernicke) or express (Broca) speech
anosognosia
loss of knowledge of self, lack awareness of deficit
socioemotional functioning (theory of mind, empathy, inhibition)
issues with this implicated in FTLD, suggests that the frontal lobe is important for this kind of functioning
ataxia
difficulty carrying out the movement (ataxia ‘attacks ya’)
dyslexia
difficulty reading
neglect
results after stroke usually, tend to ignore things on the left because of the way the two hemispheres attend to the visual fields. right attends to both, so knocking out right leads to left neglect
amnesia
retrograde
anterograde
temporal gradient
fugue
memory loss
retro - loss of memory before accident
antero- can’t form new memories post-accident
temp gradient- loss of memory right before and right after accident, looks like gradient where most loss is around time of accident
fugue- dissociation, psychological state w/ no organic cause
cortical blindness
subcortical processing of vision
blind sight
think you can see, but no awareness
neuron structure
axon, soma, dendrites, myelin, electrical signals, resting potential, neurotransmitters
meninges
dura mater (tough), arachnoid mater (spider web-y), pia mater (tender)
cerebrospinal fluid
liquid that fills the ventricles and suspends the brain
Also runs through the spinal tract and menages
blood-brain barrier
tight junctions that are only permeable to fat soluble molecules
white matter
paler tissue, mostly nerve fibers with myelin sheath. loss of this usually impacts processing speed
Inner, sub-cortex
gray matter
tissue consisting of dendrites, glial cells, synpases, capillaries
Outer, neocortex, information created
corpus callosum
connecting fibers between two hemispheres
Separation causes disconnection syndrome
anterior commissure
connects the frontal lobes
motor and somatosensory strip
motor -
somatosensory -
sulci and gyri
sulci (grooves, like the valleys, sulci sounds like sunken)
gyri (bumps, like the peaks)
Stroke
interruption of blood supply to the brain
Alzheimer’s
progressive disease that destroys memory, people generally still have their social graces intact
bvFTD
behavioral variant frontotemporal disorder
characterized by early and progressive changes in personality, emotional blunting and/or loss of empathy.
Parkinson’s
lack of movement, caused by death of the substantia nigra leading to less dopamine
Huntington’s
excessive movements, inherited disorder
Hydrocephalus
build up of fluid in the brain
Seizures
abnormal electrical activity
Callosotomy
resection
psychosurgery
cutting corpus callosum
cut out tumor
lobotomies
Multiple Sclerosis
degredation of the myelin sheath, processing speed slowed
Autism Spectrum
issues with normal social functioning
Praeder- Willi
overeating, insatiable hunger, knockout of paternal gener
Fragile X
intellectual, inherited disorder
Cerebral Palsy
movement disorder
Down’s syndrome
intellectual, random mutation
Rhett’s disorder
degeneration after 6-18 months
Angelman’s
severe intellectual impairments (can’t talk, etc.) but are sweet and “angel-like”
anterior vs posterior rostral vs caudal medial vs lateral dorsal vs ventral ipsilateral vs contralateral proximal vs distal
front vs back beak vs tail middle vs side back vs stomach same side vs opposite side close vs far
Major function/ area: basal ganglia
dysfunction implicated in movement disorders
Dopamine pathway
