glossary Flashcards
forebrain
telencephalon and diencephalon
central sulcus
separates parietal lobe from frontal lobe and primary motor cortex from primary somatosensory cortex
parietal lobe
processing sensory information
occipital lobe
visual processing centre
temporal lobe
primary auditory perception- language emotion, comprehension
lateral sulcus
prominent feature of the brain, deep groove
frontal lobe
cognitive skills, such as emotion, problem solving, memory, language, judgment and sexual behaviour
CNS
central nervous system
PNS
autonomic and somatic
autonomic NS
bodily functions
somatic NS
reflex and voluntary movement
addititive synthesis
add pure tones to create complex
fourier analysis
break complex waveforms into pure tone components
myopia
lens of eye too strong for length of eyeball
hyperopia
lens of eye too weak for length of eyeball
trichromacy
can see all coours
dichromacy
colour deficits
tritanopic
lost s opsin
deuteranopic
lost m opsin
protanopic
lost l opsin
dualism
mind and brain fundamentally different
monoism
operations of brain lead to mental events
sub-cortical nuclei
involved in movement control
olfactory celft
relays sensory info to brain
olfactory epithelium
tissue that lines outer surface of organs and blood vessels
striatum
caudate nucleus and putamen
globus pallidus
voluntary movement
limbic system
cingulate cortex, amygdala and hippocamous
cingulate cortex
error signals /attention/emotion
amygdala
emotion- fear
the cochlea
receives sound as vibrations
vestibular canal
spatial orientation, awarenss and balance
corti
hair cells here trnsduce mechanical sound vibration
stereocilia
convert vibrations into nerve impulses
tonotopy
arangement of where sounds of different frequencies are processed in the brain
basiliar membrane
separates two liquid filled tubes that run along the coil of cochlea
helicotrema
hair cells here detect low frequencies
utricle
balancing system using hairs to detect movement and orientation
pupil
control amount of entering light
iris
control amount of entering light
sclera
sheath covering optic nerve behind
cornea
eyes outermost lens
fovea
let light fall directly on cones to give sharpest image
retina
converts light into neural signals
vitreous
transparent gelatinous tissue filling eyeball
ciliary body
ciliary muscle which controls shape of lens
emmetropia
no visual defects in sight
2nd order
the new CS tells u about old Cs
blocking conditioning
new CS tells u nothing new
presbyopia
long sightedness
scotopic vision
processing disorder
photopic vision
vision under well lit conditions
ganglion cells
neuron which recieves info from photoreceptors; bipolar and retina amacrie
anterograde amnesia
cannot later remember events that occur after brain damage
korsakoffs syndrome
damage to dorsomedial thalamic nucelus
LGN
lateral geniculate nucleus -
excitatory centre
light turns on
inhibitory surround
light turns off cell
object agnosia
failure to recognise objects
prosopagnosia
face agnosia
dura mater
thick membrane which surrounds brain and spinal chord
pia mater
delicate innermost layer of membranes surrouding brain and spinal chord
telencephalon
the cerebral cortex
basal ganglia
motor movements , procedural learning habit learning eye movement etc
