1) Read an record brain activity
2) match brain activity to action with computer algorithm
3) end interpreted to signal to machine
4) machine produces movement
True or False
An example of active prosethic control is when limb movement is required to produce prosethic action
True
True or False
A brain machine/controlled interface is like an inverse internal model
True
True or False

True or False
A new connection formed between two neurons is a mechanism of plasticity?
True
axon collateral is a branch off another axon to connect them
