1 Why is the story of Phineas Gage considered so extraordinary? What does his story teach us about the brain? Phineas Gages’s story is so extra ordinary because a metal rod was impaled through his head and destroyed most of his frontal lobe. His story has taught us that different parts of the brain control different things and the part of his brain that got injured effects a person’s memory, personality, and emotion.
2 New research is using functional MRI (magnetic resonance imaging), a scan of the brain that shows specific areas that are activated during certain tasks, as a lie detector test. Explain which area(s) of the brain you think might light up to show that you are telling a lie or telling the truth. Explain your reasoning. The part of the brain that would light up when you are lying or telling the truth would be the frontal lobe. This lobe is in charge of an individual’s personality, memory, and emotion that are all things that would be triggered in a lie detector test.
3 Explain the function of the brain’s limbic system.
The brains limbic system is located in the core of the brain and includes the amygdala, hippocampus and hypothalamus. It is in charge of regulatings the brains, memory, emotion, and some movement. 8. Return to the first paragraph of Activity 2.1.2: Build-A-Brain and re-read the description of your morning activities. Use your map to determine the part of the brain responsible for each of the actions, thoughts or emotions that occur in this paragraph. Either re-write the paragraph and add brain regions in () after each activity or simply list the actions and write the brain region next to it. – whether the action is smelling the roses (Olfactory), feeling pain(parietal), (motor cortex)moving a leg, or distinguishing a cow from a horse (frontal). 9.Ten-year-old Alex Fuentes damaged his occipital lobe and his cerebellum in a car accident.
Explain to his parents some of the possible effects of this injury. Alex Fuentes damaging both his occipital lobe and cerebellum can lead to several substantial effects. Some handicaps that can occur from damage to the cerebellum is loss of balance, poor posture, no use of muscles and their coordination. Losing coordination of the muscles can stop the use of extremities. More possible effects of damaging the occipital lobe from the car accident can lead to 10-year-old Alex Fuentes to losing vision: blurry, clouded vision, or complete blindness.
