Read the following passage carefully, then click on the "next page" button to return to the CourseInfo page. (You may have to "find" the quiz again under the "Assignments" button.) Feel free to leave this browser window open so that you may easily refer back to the passage in question.
(Note to those who found this site via an Internet search: This lesson on using sources is open to the public, but the following assessment is available only to students enrolled in my Advanced Composition class during the fall 1999 semester. It requires a user ID and password as well as "enrollment" in the CourseInfo system at the University of Mississippi.)

We can now recognize the very attractive possibility that the left hemisphere of the neo-cortex is suppressed in the dream state, while the right hemisphere which has an extensive familiarity with signs but only a halting verbal literacy is functioning well. It may be that the left hemisphere is not entirely turned off at night but instead is performing tasks that make it inaccessible to consciousness: it is busily engaged in data dumping from the short-term memory buffer, determining what should survive into long-term storage.
