3D Brain Scavenger Hunt Activity Location Location 1: Which is more medial: Hypothalamus or Hippocampus? Hypothalamus Location 2: What structure is the lower-most junction between the spinal cord and the brain? Medulla Location 3: What is the dentate gyrus part of? Hippocampus Location 4: Which lobe contains Broca’s area? Which lobe contains Wernicke’s area? The frontal lobe has Broca’s area, and the temporal lobe has Wernicke’s area Location 5: Which structures are included in the limbic system? The hippocampus, Entorhinal Cortex, Cingulate Gyrus, Amygdala, Dentate Gyrus, and Hypothalamus Location 6: Where is the cingulate gyrus? (using anatomical directions) It is on the medial side of the cerebral hemisphere. Function Function 1: Which structure would likely be most clearly activated when someone is afraid?
The Amygdala Function 2: Which structure would be involved in regulating circadian rhythms? The Hypothalamus Function 3: What behaviors would likely be affected if someone had damage to the prefrontal cortex? It would affect someone’s social skills, attention span, and voluntary behavior (like problem solving, planning, and decision making) Function 4: What would a person perceive if their superior temporal gyrus was stimulated? They would process sound and comprehend languages. Function 5: Damage to which area could cause hemispatial neglect? The parietal lobes Application Patient #1 fell off a ladder onto a sharp piece of metal. The metal damaged an area that is a target for many sensory cranial nerves and sends many projections to different sensory regions of the cortex. What part of the brain did the nail hit? The Thalamus Patient #2 suffers from severe epilepsy and has very bad seizures. Medication has been ineffective. What part of the brain might doctors cut to prevent the spread of electrical activity across cerebral hemispheres? Corpus Callosum Patient #3 was knocked unconscious by a falling branch. When he awoke, he reported light sensitivity, seeing bright lights, and blurred vision. Which lobe, associated with visual processing, may have been damaged by a concussion from the branch? Occipital lobe Patient #4 was accidentally shot in the head by a small bullet. The bullet damaged the limbic system structure associated with expressions of fear, excitement and arousal. Where is the bullet? The amygdala Patient#5 has been diagnosed with Parkinson’s Disease (PD), a degenerative brain disorder that affects voluntary movement. What specific sub-region of the midbrain has been correlated with
