Hippocampus Corpus Callosum Motor Cortex Broca's Area Contributes to the formation of memories or road hazards and directions Corpus Callosum Contains sensory and motor driving information from both left and right hemispheres of the brain Motor Cortex Initiates driving actions like moving the foot to the brake Broca's Area Enables drivers to converse with other passengers and curse at drivers Prefrontal Cortex Helps to plan routes Sensory Cortex Registers the pressure of the right foot on the gas pedal or brake Visual Cortex Processes visual road signs like stop signs and speed limit signs Cerebellum Coordinates left and right hand movements on the steering wheel Medulla Regulates breathing and heart rate to concentrate and in dangerous situations Pons Assists the coordination of driving motions and alertness Reticular Formation Controls alertness and drowsiness while driving Thalamus Sends visual and auditory information to areas of the cerebellum Hypothalamus Makes us aware of body temperature, to adjust temperature controls, and if we're hungry or thirsty Amygdala Active during road rage
