  divided into two parts the right and left
  hemispheres.
• The right is responsible for artistic expression
• The left is responsible for problem solving,
  decisions, and language.

The Brain Stem

• This is in the bottom of the brain, at the top of
  the spinal cord. It has 2 main parts the pons
  and the medulla.
• It controls sleeping, awakening, dreaming.

5
The Limbic System

• This is found deep inside the brain. It is made
  up of several parts including the hippocampus and
  the amygdala. It is responsible for learning,
  memory, and emotions. This part of the brain is
  greatly affected by drugs, such as alcohol and
  nicotine.

6
The Cerebellum

• The cerebellum is the part of the brain located
  in the back of the head. It controls posture,
  movement, and the sense of balance.
• Playing basketball, dancing, picking up your
  backpack all require this part of the brain.

7
Frontal Lobe

• Located behind the forehead.
• Responsible for initiating and coordinating motor
  movements and problem solving

8
Parietal Lobe

• Located behind the frontal lobe
• Processes sensory information from the whole body
  (information about pain, touch, and pressure)

9
Occipital Lobe

• Located in the back of the brain
• Processes all the visual information coming into
  the brain

10
Temporal lobe

• Located behind the temples and just above the
  ears
• In charge of making sense of the information you
  hear
• Integrates information from various senses such
  as smell and vision
