How do thoughts and emotions occur?
Thoughts and emotions occur as the result of an active lifestyle
Thoughts and emotions occur due to involuntary responses in the spinal cord
Thoughts and emotions occur only when the brain processes voluntary responses
Thoughts and emotions occur as a result of the way a stimulus makes you feel
Which of these is true about how injuries affect the brain?

An injury in a particular region of the brain may result in the gradual loss of all brain
An injury in a particular region of the brain may result in the loss of a specific function
An injury anywhere in the brain results in the immediate loss of all functions
Which device do scientists use to study brain regions in non-injured brains?
electrocardiograms
electron microscopes
functional magnetic resonance imaging
