lecture 3, Flashcards
neural basis for cognition
cap gras syndrome
hint: you are cap
is where people think their loved ones are_____
and dont have any ______ __ to the people they see and believe that their person was____
imposters
they are physically able to recognize their face
emotional connection to the imposter
kidnapped
if a person keeps saying somone replaced their wife with a clone, is able to regocnize their face but have no emptional connection with them they likely have what syndfrome?
capgras syndrome
the 2 parts of the brain that are involved in capgras syndrome/facial regognition are
____ lobe and _____
which indicate that facial recognition is incvolved in both
temporal lobe
amygdala
facts and emotional connection
the amygda is responsible for
the part in the amygdala thar is responsible for emotional recognition is called the __ __ __
the emotional center of the brain, processing of faces
FFA
this partt of the brain is responsible for RECOGNIZING physical faces
temporal lobe
becuse the amydla and the FFA work together for facial recognition, people with capgras syndrome have damamges in the
why also the prefrontal cortex?
connections between the FFA and amygdala and also the prefrontal cortex
because damage= illogical thoughts running without check system
controloing behavior decison making, controling cognition is the job of the
prefrontal coirtex
3 major structures in the brain
1.
2.
3.
hinebraine
midbrain
forebrain
fx of the hinebrain
heartbeat, breathng, ;osture, balance, alertness
fx of the cerebellum
hint: belle from beauty and the beast
movements and balance
spatial reasoning
sound discrimination
sensory ingreation
medula
center or resporarion and swalling
nerves travel through this
midbrain function
motor, sleep, awaefullness
eyemovement
auditory pathwats from ears to the forebrain
pain experiences
forbrain is
the 5 lobes of the forebrain are
parts of brain visible from outer surface
frontal lobe, parital lobe, temporal lobe, ociptal lobe, temporal lobe
this is the outer surface of the brain
what is the functions of this outer layer of the brain?
cerebral cortex
the cerebral cortex makes up ____ of the brain
80%
thalmus
relay station for all info going into the cortex
hypothalamus
hint 4 Fs
motivated bahaviors, eating, drinking sexual activity
limbic system\
what does this include
interconnected structures around thalamus and hypothalamus
amydala, hypocampus
think bundles of fibers that cary info between the 2 hemespheres are
commisures
commisures are
the larges commisure is the
hint: bridge in corpus christi
think bundles of fibers that cary info between the 2 hemespheres are
courpus collusum
left hemisphere job
language, recieve info from righ
local info
right hemisphere job
global infor, recieve info from left
spaical/visual info
split brain pt
tells us
tx for dec eplipsy
neropsych people study
understant fx of brain damage
ct scans
3d imaging slices of the brain that tells us size shape
fmri
measures the blood oxygen of the brain
eeg
what is
pros and cons
measures firing and action potentials
pros: hightempral
con: low spatial resolution, only measure surface
petscan
fmri
pros and con
can detect brain structure
cons: can detect brain activity
TMS
uses magnetic pulses and gives causal data
what can brian scans do:
overlap between brain structures
the cerebral cortes is the _____ portion of the human brain and it is divided into the m____ areas, S____areas and the A____ areas
motor, sensory, association
largest part of human brain
motor projection areas
inc of cortical coverag=
signal entrance and exit to tell muscles to move
more movement
sensory areas
75% of the cerebral corteex is made of ____ areas
a____ areas damage =
association areas
aprazia, aphasia, neglect syndrome, prefrontal damage
know what aphasia, apraxia, agnosia, neglect syndrome, and prefrontal damage is
what is agnosia, pertaining to the lack of us/we
if i cant IDEntify us then what does that mean?
neglect syndrome=
agnosia= problems with identifying familar objects
problems when half the visual world is ignored
glia cell fx
repair damage, amke mylon sheeth
neuron is a type of
brain cell
dendrite fx
detect brain signal
cell body
contains the nucleus and cellular machinery
axon
transmits signals to other neurons
