Direct stimulation of the motor cortex would most likely result in movement of the mouth and lips, as the motor cortex controls voluntary movement of the body, including the muscles involved in speech and facial expression. Stimulation of the motor cortex would not likely result in feelings of anger or acceleration of heartbeat, which are controlled by other areas of the brain. A sensation of being touched on the arm would be more likely to result from stimulation of the somatosensory cortex, which receives sensory input from the body.
