Question: Name two roles the parietal lobe play. Answer: Integrating sensory information from various senses. The manipulation of objects. Visuospatial processing. Question: Question: Question: Where is the parietal lobe located? Where is the primary somatosensory cortex located? What information is processed by the primary somatosensory cortex? Name at least two. Answer: superior to the occipital lobe posterior to the frontal lobe. Answer: In the parietal lobe Immediately posterior to the central sulcus of the brain (the post central gyrus). Answer: Sensory information such as: touch pain visual auditory olfactory taste. Question: Question: Which hemisphere of the primary somatosensory cortex is activated by tactile stimuli on the left side of the body? Which hemisphere of the primary somatosensory cortex is activated by tactile stimuli on the right side of the body? Answer: The right hemisphere. Answer: The left hemisphere Question: Question: What determines how sensitive a part of the body will be to touch? What is phantom-limb sensation? Answer: The number of nerve endings in that area. Answer: The impression that an amputated limb is still present and in some cases painful. Question: What is neural plasticity? Answer: Neural plasticity is the ability of the nervous system to form new neural pathways in response to physical damage such as amputation. Question: How is neural plasticity important for the development of phantomlimb sensations? Answer: phantom- limb sensations could be a result of plastic changes in the somatosensory cortex. Question: Which of the following age groups would have the greatest amount of neural plasticity? A. 1-10 years B. 11-20 years C. 21-30 years D. 60-70 years Answer: A. 1-10 years Question: Neural plasticity would be least important for which of the following? A. Recovering mental functions lost due to brain damage. B. Learning a new fact about biology. C. Forming a memory of what you did last night. D. Neural plasticity would be equally important for all the above. Answer: D. Neural plasticity would be equally important for all the above. Question: Question: Question: What is "anosognosia”? What is "left-side neglect"? Answer: Left-side neglect is a form of attention deficit where a person no longer acknowledges the left side of his/her body or space. What is its primary cause of "left-side neglect"? Answer: Damage to the right parietal lobe. Answer: The person with right parietal lobe damage is unaware of the problems that he or she is experiencing. Question: What is agraphia or dysgraphia? Answer: A writing disability. Question: What is acalculia or dyscalculia? Answer: A lack of understanding of the rules for calculation or arithmetic. Question: What is finger agnosia? Answer: An inability to identify fingers. Question: What is simultanagnosia? Answer: An inability to perceive more than one object at a time. Question: What is the name for an inability to fixate and follow an object with one's eyes? Answer: Optic apraxia. Question: Question: What is optic ataxia? Question: What is nociception? Answer: A severe misreaching for objects. Answer: The processing of pain. Question: What separates the parietal lobe from the temporal lobe? Answer: Sylvian fissure, or Lateral sulcus, or Lateral fissure. Which task would not be affected by damage to the right parietal lobe? A. Shape recognition. B. Dressing. C. Doing arithmetic. D. Writing. Answer: D. Writing. Question: Which part of the cereberal cortex is most likely damaged if a patient is experiencing difficulty sensing touch on the left of his body? A. The right parietal lobe. B. The left parietal lobe. Answer: A. The right parietal lobe. Question: Which of the following is a person most likely to experience following damage to the somatosensory cortex in the left parietal lobe? A. Left-side neglect and anosognosia. B. Right-side neglect and anosognosia. C. Problems with tactile perception on the left side of the body. D. Problems with tactile perception on the right side of the body. Answer: D. Problems with tactile perception on the right side of the body.
