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?arrow_forwardWatch 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?arrow_forward

Please provide some visualizations and diagrams to go along with your explanation. So, please only include the circuit loop and not any pictures of the brain.

- Which of the following situations is associated with movement and position in the human body? a. Statoliths in statocysts bend sensory hairs and trigger actionpotentials. b. If sensory hairs in the utricle are oriented horizontally andthose in the saccule are oriented vertically, the person is lyingdown. c. When the head rotates, the endolymph in the semicircularcanal pulls the cupula with it to activate sensory hair cells. d. Displacement of the utricle and saccule generates actionpotentials. e. If the body is spinning at a constant rate and direction, thecupula is displaced and action potentials are initiated.arrow_forwardWhich of the following could be elements of cyto architecture, as related to Brodmanns microscopic studies of the cerebral coitex? connections to the cerebellum activation by visual stimuli number of neurons per square millimeter number of gyri or sulciarrow_forwardReverse Firing of neurons allows for ? 1.

Often, the action potentials occur so rapidly that watching a screen to see them occur is not helpful. A speaker is powered by the signals recorded from a neuron and it pops each time the neuron fires an action potential. These action potentials are firing so fast that it sounds like static on the radio. Electrophysiologists can recognize the patterns within that static to understand what is happening. Why is the leech model used for measuring the electrical activity of neurons instead of using humans?arrow_forwardRead this article (http://openstaxcollege.org/l/3word) to learn about a young man who texts his fiancée in a panic as he finds that he is having trouble remembering things. At the hospital, a neurologist administers the mental status exam, which is mostly normal except for the three-word recall test. The young man could not recall them even 30 seconds after hearing them and repeating them back to the doctor. An undiscovered mass in the mediastinum region was found to be Hodgkins lymphoma, a type of cancer that affects the immune system and likely caused antibodies to attack the nervous system. The patient eventually regained his ability to remember, though the events in the hospital were always elusive. Considering that the effects on memory were temporary, but resulted in the loss of the specific events of the hospital stay, what regions of the brain were likely to have been affected by the antibodies and what type of memory does that represent?arrow_forward
