lateral view: label each lobe of the brain plus the motor and somatosensory cortices and write one word summarizing the function of each lobe next to its label\npractice: use your book and notes to answer the following application questions\n1. what is the difference between a sensory area of the brain and an association area?\n2. how have brain injury case studies like phineas gage helped reveal the function of different brain areas throughout the history of neuroscience?\n3. what brain area do all senses pass through except smell? what do you think would happen if there was a lesion in this brain area?

Answer

Brief Explanations:

  1. Sensory areas receive and process sensory information directly from the body's senses. Association areas integrate and interpret the information from sensory areas, and are involved in higher - order cognitive functions like memory, thought, and decision - making.
  2. Brain injury case studies like Phineas Gage's showed how damage to specific brain areas led to changes in behavior, personality, and cognitive functions. This allowed researchers to infer the normal functions of those areas. For example, Gage's frontal lobe injury changed his personality, indicating the frontal lobe's role in personality and decision - making.
  3. All senses except smell pass through the thalamus. A lesion in the thalamus could lead to sensory deficits such as impaired vision, hearing, touch, or taste, as it acts as a relay station for sensory information.

Answer:

  1. Sensory areas process direct sensory info, association areas integrate and interpret it for higher - order functions.
  2. Brain injury cases show how damage to areas changes behavior, helping infer normal functions.
  3. Thalamus; could lead to sensory deficits.
