perceptual concept
dominance of one sense over other modalities creating a percept due to spatial reliability
ex - ventriloquist effect, nose/olfaction captured by mouth/taste&touch
combining/integrating sensory sources
combines alarm systems
helps with object identification
allows for visual-auditory localization
sufficient information for control of locomotion
object unity
cohesion of the world achieved through integrating sensory information
redundant information
2+ sensations about a single events
ex - what you see & what you hear
non-redundant information
sensing the movement/spatial orientation of the sensor
ex - what you see & how the eyes move
superior colliculus
single cell in cats that receives input from multiple senses therefore multimodal receptive fields
bimodal neurons
responds to light and touch
in premotor cortex of monkeys
ex - hand-centered visual receptive field & tactile receptive field
crossmodal identification
fMRI activation in the same areas that activate in respond to different senses
ex - integration of visual & auditory information
unimodal areas
area of brain that only activates in response to one sense
multimodal areas
area of brain that activates to 2+ senses (not necessarily at the same time)
body schema
dynamic online-representation of the body in space from somatosensory afferences
rubber hand illusion
manipulation of body schema through vision
out of body experience (OBE)
sensations in which consciousness becomes detached from the body, taking up a remote view point
caused when stimulating angular gyrus
vestibular illusions
phenomenal consciousness
experience, subjectivity
may be similar to multisensory capture
we will never know what it is
