Homework Answers

Answer #1

1. B. Electrically stimulate their right motor cortex

The left side of the brain is controlled by the right hemisphere, this rule is only changed in case of vision.

2. B. prefrontal cortex

The pre frontal cortex is also referred to as the impulsivity control area which is responsible for carrying out the executive functions that includes impulse control, judgment, emotion management and critical thinking.

3. A. It gives poor information about the timing of brain activity.

This stays as one of the major disadvantages where it becomes very difficult to identify the pockets in the brain from which the electrical activity is arising. Some idea can be obtained by adding many electrodes but it doesn’t give a proper idea.

4. A. parasympathetic

Resting and digestion and lowering heart rate is the action of the parasympathetic nervous system whereas the sympathetic nervous system causes the flight or fight response.
