- In the ___, neurons are arranged like maps that correspond to different parts of the body surface. a. retina b. somatosensory cortex c. basilar membrane d. occipital lobeWatch this video (http://openstaxcollege.org/l/2point) to see a quick demonstration of two-point discrimination. Touching a specialized caliper to the surface of the skin will measure the distance between two points that are perceived as distinct stimuli versus a single stimulus. The patient keeps their eyes closed while the examiner switches between using both points of the caliper or just one. The patient then must indicate whether one or two stimuli are in contact with the skin. Why is the distance between the caliper points closer on the fingertips as opposed to the palm of the hand? And what do you think the distance would be on the arm, or the shoulder?Queation 13 Corbetta's research on the neuroscience of attention indicated that _______________. a. attention orientation affected orientation columns b. attention cannot really be localized c. EEG and MRI do not yield the same results d. attention to different stimulus dimensions activates different brain regions e. all of the above

- Mechanoreceptors in the ___ send signal, to the brain about the body's position relative to gravity. a. eye b. ear c. tongue d. noseWatch this animation (http://openstaxcollege.org/l/braindevel) to examine the development of the brain, starting with the neural tube. As the anterior end of the neural tube develops, it enlarges into the primary vesicles that establish the forebrain, midbrain, and hindbrain. Those structures continue to develop throughout the rest of embryonic development and into adolescence. They are the basis of the structure of the fully developed adult brain. How would you describe the difference in the relative sizes of the three regions of the brain when comparing the early (25th embryonic day) brain and the adult brain?Compared with the nearest evolutionary relative, the chimpanzee, the human has a brain that is huge. At a point in the past, a common ancestor gave rise to the two species of humans and chimpanzees. That evolutionary history is long and is still an area of intense study. But something happened to increase the size of the human brain relative to the chimpanzee. Read this article (http://openstaxcollege.org/l/hugebrain) in which the author explores the current understanding of why this happened. According to one hypothesis about the expansion of brain size, what tissue might have been sacrificed so energy was available to grow our larger brain? Based on what you know about that tissue and nervous tissue, why would there be a trade-off between them in terms of energy use?
