Questions about Brain Damage?

Paul suffers from post-traumatic stress disorder. His emotions, especially depression and anxiety, are running out of control. Locate the probable site of his brain lesion. AMYGDALA Anoxia (lack of oxygen) during birth left Kevin uncoordinated. His movements are jerky because of damage to his “little brain” that controls motor movement. His brain damage is probably located where? Cerebellum? Jimmy has Korsakoff’s syndrome. He lives in a psychiatric institute. Each time his neurologist visits, Jimmy says, “Hi ya, doc, how are you doing?”. But even though Jimmy has talked to his neurologist dozens of times, he actually doesn’t remember ever having met him before. He only recognizes him as a doctor because of his white lab coat. However, Jimmy can remember all his life events before he became ill and can describe in detail his experiences in World War II. Which of Jimmy’s brain structures is likely damaged? - this is either the THALAMUS OR HIPPOCAMPUS (i think i have this narrowed down) Due to a drug overdose, the area of Todd’s brain which relays sensory information (such as that involving sounds, sight, taste and touch) to other areas of his brain is damaged. Todd remains in a catatonic, unresponsive state. Where is the damage? - the thalamus (forebrain)? Mary has epileptic seizures. Mary reported that the seizures are usually preceded by an “aura” which involves the sensation that something is touching her right leg. This gave the neurologist a clue as to the lesion’s location. Where is her epileptic “focus” likely to be? - parietal lobe of cerebellum ; primary somatosensory complex During an operation for the removal of damaged brain matter, the surgeon stimulated the brain with an electrode. The patient reported hearing music. Where was the electrode placed? - the temporal lobe of cerebellum? Lunar pilot Edwin Aldrin reported seeing mysterious flashes of light during the Apollo II mission. The visual display apparently resulted from the high energy particles passing through these portions of the brain. - i have no idea about this one!! Nona was driving home after the night shift. She was very tired and the roads were bad. Her car hit a pot-hole that was invisible in the rain. It threw her car off the road and she slid to a sudden stop, assisted by a telephone pole. As her head hit the window, she passed out and woke up in the hospital several days later. Although Nona seemed to recover completely, her friends and family report that she seems like a different person. She is less responsible about going to work, and she is louder and less polite than she used to be. Where do you think the damage is? - frontal lobe of cerebellum Granny was sitting in her chair watching TV. She tried to reach for the remote and noticed that she could not move her left arm. She could feel things that touched her hand or arm, but her arm no longer responded to her wishes. Where’s the damage? - primary motor cortex of frontal lobe I believe the answer to the first question is right, however having trouble with the rest.. but put what I THINK is RIGHT. Thanks for ANY help!

1. There are no parietal lobes in the cerebellum; they are in the cerebrum (cortex). 1. Perhaps the amygdala, but most likely to be the inferior portion of the prefrontal cortex and basal ganglia. 2 Cerebellum 3. temporal lobes bilaterally. 4. brainstem and posterior sensory association cortex. 5. left hemisphere, lower aspect parietal lobe (posterior to the Sylvian Fissure on the sensory strip) Refer to the homunculus. 6. Right frontal lobe. 7. Right hemisphere primary motor cortex, but I would also investigate thalamus and internal capsule in the right brain..
