Rebecca Kent Prof. Maxwell Psychology 111 1 March 2021 Brain Structures/Functions Extra Credit 1. Julia had a brain infection and a high fever at the age of two. The illness may have led to spells of aggression and fear that she began having by age 10. Locate the probable site of her brain lesion. Amygdala 2. Lunar pilot Buzz Lightyear reported seeing mysterious flashes of light during the Apollo 11 mission. The visual display apparently resulted from high energy particles passing through this region/area of the brain. Occipital Lobe 3. After slipping and falling on ice, and hitting the back of her head, Karen stopped breathing for several minutes. In addition, her heart rate and breathing became very irregular. Where might the damage have been? Medulla 4. Mary has epileptic seizures. Mary reported that the seizures are usually preceded by an “aura” which involves the sensation of something touching her right leg. This gave the neurologist a clue as to the lesion’s location. Where is her epileptic focus likely to be? Somatosensory Cortex 5. Harry, a 33-year-old executive, suffered a stroke that left him without the ability to speak. The stroke probably cut off the blood supply to this area. Broca’s area 6. Polly had a rare and severe form of epilepsy that could not be controlled by medication. Surgery stopped the seizures but seemed to have little effect on her everyday thinking, talking, and acting. However, in the laboratory, she was unable to name/identify the object that was placed in her left hand. It was as if the two hemispheres of her cerebral cortex were not communicating. Indicate the location of her surgical lesion. Corpus Callosum 7. During an operation for the removal of a brain scar, the surgeon stimulated the brain with an electrode. The patient reported hearing music. Where was the electrode placed? Auditory Cortex Kent 1

8. Anoxia (lack of oxygen) during birth left Kevin uncoordinated. His movements are jerky because of damage to the “little brain” that controls motor movement. His brain damage is located where? Cerebellum 9. Iris was in an automobile accident, where she suffered extreme head trauma. She lost the ability to form new memories. Which structure or area of the brain was damaged? Hippocampus 10. At the age of 3, Raul stopped growing. After many tests and examinations, a tumor was discovered to be interfering with the function of this particular structure in the brain. (Hint: This structure is a gland in the endocrine system) Pituitary Gland Kent 2
