B) abnormal eating behaviours occurred because the cats could not regulate hunger. C) one side of the brain did not know what the other side was doing. D) disorganized electrical activity spread from one hemisphere to the other. 283) Which of the following statements is NOT true? A) Each hemisphere controls the opposite side of the body. B) The two hemispheres share many of the same functions, but also are specialized for other functions. C) The two hemispheres communicate with each other through the corpus callosum. D) Each hemisphere receives sensory input from the same side of the body, but controls movement of the opposite side of the body. 284) The primary reason for performing split-brain surgery on humans was to: A) reduce the tremors, stiffness, and rigidity of severe Parkinson’s disease. B) find out what each half of the brain can do, cut off from the other. C) find out whether the two hemispheres would develop an alternate means of communication. D) reduce the seizures in patients with debilitating, uncontrollable epilepsy. 285) Researchers took photographs of different faces, cut them in two, and pasted different halves together to form composite faces. The reconstructed photographs were flashed quickly to split-brain patients. It was found that the split-brain patients would: A) name the person in the right part of the image and point with the right hand to the left image. B) name the person in the left part of the image and point with the right hand to the left image. C) name the person in the right part of the image and point with the left hand to the left image. D) name the person in the left part of the image and point with the left hand to the right image. 286) If you look straight ahead, then everything in the left side of the scene before you goes to the: A) left half of your brain. B) right half of your brain. C) back half of your brain.

B) actually say what the object is, but refuse due to his condition. C) point to the object with his right hand. D) point to the object with his left hand. 288) Which of the following is primarily a function of the right hemisphere? A) solving mathematical problems B) understanding technical material C) recognizing faces D) language 289) The left hemisphere contains regions that are: A) active during the creation of art and music. B) associated with the tendency to withdraw from others. C) active when language is processed. D) associated with negative emotions, such as fear and sadness. 290) In a classic split-brain study, a picture of a chicken claw was flashed to the left hemisphere while a picture of a snow scene was flashed to the right hemisphere. When asked to choose a related image from an array of pictures: A) the left hand pointed to a shovel and the right hand pointed to a chicken. B) the left and the right hand both pointed to the shovel. C) the left and the right hand both pointed to the chicken. D) the right hand pointed to a shovel and the left hand pointed to a chicken.
