The Brain's Sense Of Movement- Berthoz Flashcards
1
Q
How is perception constrained by action?
A
It is an internal simulation of action
2
Q
What is a motor schema?
A
Memorized relationships between sensory and motor components of action
3
Q
How do muscle spindles make up for slow muscle contraction times?
A
Spindle discharge is maximal before elongation is complete, due to velocity detection (predicts eventual length)
4
Q
What are y motor neurons
A
Motor neurons at end of muscle spindles that allow modulation of reflex responses/sensory information
5
Q
How do the vestibular receptors work with spindles to anticipate loss of balance?
A
Spindles sensitive to stretch velocity, and vestibular receptors sensitive to acceleration supplies the nervous system with preliminary info
