Perception
what is
perception
bensation detection of internal or external
stimulation Raw info abt the
environment is made available
to the brain senses
through
Perception awareness s interpretation of
brain
sensory info by
Perceptual defects can occur w o
sensory impairment
blindness
able eg to detect but
cant see
light
electrical activity
t cells
visual info subcortical
travels from retina
areas
through Ycipital lobe
V1 is content to to PVC
first place of
recieve visual info
V1
Damage
Patients with leisions to the PVC
large
retain SOME VISUAL ABILITIES
occasionally
BLINDSIGHT
For Better than chance
eg
on Force choice
performance
Discrimination
Task
distinguish btw reds green
, V1 is not the
only path
this condition spatial Navigation s
ppl w
coordination are good
i e avoid obstacles interact w

used TMS to knock the activity
inhibitory is ability to report
of PVC there
features even w o consciously seen
visual corticles
Higher mthiffier
secondary visual cortices 125
reciene much of info from V1
Process visual info to
motion form etc
in

which
Depending on damage can see
perceptual dysfunction is it
Bilateral to becondry context
V5
damage loss
selective visual of
motion
perception AKINETOP 51A
visual associated content 7
recieve input
from visual content is
from cortical of one or more sensory
systems eg hearing propriception
for multisensory integration
sound info a visual into
eg combining
one
