Concept explainers
Read 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 Hodgkin’s 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?

- Watch this video (http://openstaxcollege.org/l/neuroexam) that provides a demonstration of the neurological exam—a series of tests that can be performed rapidly when a patient is initially brought into an emergency department. The exam can be repeated on a regular basis to keep a record of how and if neurological function changes over time. In what order were the sections of the neurological exam tested in this video, and which section seemed to be left out?arrow_forwardCompare and contrast the features of working, shortterm, and both types of long-term memoryarrow_forwardThe cerebral cortex does not play a major role in (A) short-term memory. (B) long-term memory. (C) circadian rhythm. (D) breath holding.arrow_forward
- Why it is difficult to determine the accuracy of a “memory” that is recovered in therapy?arrow_forwardDescribe how memory works at the cellular and molecular levels.arrow_forwardWhen it comes to solving math problems on tests, Brandon can recall all the formulas perfectly. But as he actively works to solve a problem, he has trouble keeping track of the variables that he manipulates in his mind. This example describes how Brandon most likely has limited ______.a) sensory storageb) working memoryarrow_forward
