Control of Movement Flashcards
smooth, accurate movement requires what kind of info?
visual, somatosensory, and vestibular info
visual info
location, texture, size, shape of objects
feeds into feedforward system
primary info given to you as feedforward control
somatosensory info
cutaneous and proprioceptive info
proprioceptive info: info about muscle force, length, and position
cutaneous info: thermo, chemo, and mechoreceptors
known to be very important for motor learning
vestibular info
balance and head movement
what is kinesthetic sensation?
movement and body in space
what is the visual action stream (dorsal stream)?
info from visual cortex–> posterior parietal cortex–> premotor cortex
visually guided movement
flows dorsally
give info about what actions you need to be making and what actions you’re currently making
spatial awareness and guidance of action
constant feedback
posterior partietal info in visual action stream
neurons associated with vision and movement
premotor area in visual action stream
reaching, grasping, and eye movement
