The unit provides information on the study of the human brain for students in grades 5-9 with suggestions for extending the lessons for gifted and talented students. Learning activities are offered for ten lessons (sample subtopics in parentheses); introduction to the unit (student pretest and posttest); brain growth; medulla-oblongata-reptilian brain; cerebellum-lumbic brain; cerebrum-neocortex-new mammalian brain; hemisphericity (the mind's dual nature, styles of learning and thinking); the hemispheres (right brain and left brain functions in terms of styles of learning and thinking); the senses; long and short term memory; and the positive potential of the brain. Extended learning activities require higher level thinking on topics such as dreams, extra sensory perception, the biochemistry of emotions, and phobias.
