Normal Brain

This is a CT scan of a normal adult brain. The frontal lobes of the brain are at the top of the image. For comparison, here is a myelin-stained section of the brain oriented in the same way. See if you can identify the following structures on the right side of the patient's brain: 

• Skull bone 
• Brain tissue
• Fluid containing spaces ( ventricles and cisterns )
• Calcified pineal gland
