Not directly controlled by her brain . Her brain sends signals to get arm like everyone else . Skin conductance readings detected these signals and can translate them to electrical signals to control her hand . There are a variety of different signals that can be read and mapped to different movements . Any signal can be translated to do whatever the programmer wants it to do , like rotating it here . Within a few hours of training your brain , you can perform controlled movements . Edit oh I skipped a few comments explaining this .
