Theories About The Function of Rapid Eye Movements
According to "scanning hypothesis" the directional properties of REM sleep eye movements are related to shifts of gaze in dream imagery. Against this hypothesis is that such eye movements occur in those born blind and in fetuses in spite of lack of vision. Also, binocular REMs are non-conjugated and so lack a fixation point. In support, research finds that in goal-oriented dreams, eye gaze is directed towards the action described by the dreamer.
Other theories are that they lubricate the cornea, warm the brain, stimulate and stabilize the neural circuits that have not been activated during waking, create internal stimulation to aid development of the CNS, or lack any purpose, being random creation of brain activation.

Famous quotes containing the words theories, function, rapid, eye and/or movements:
“The theories and speculations of men concern us more than their puny accomplishment. It is with a certain coldness and languor that we loiter about the actual and so-called practical.”
—Henry David Thoreau (1817–1862)
“Advocating the mere tolerance of difference between women is the grossest reformism. It is a total denial of the creative function of difference in our lives. Difference must be not merely tolerated, but seen as a fund of necessary polarities between which our creativity can spark like a dialectic.”
—Audre Lorde (1934–1992)
“he dreadful darts
With rapid glide along the leaning line;
And, fixing in the wretch his cruel fangs”
—James Thomson (1700–1748)
“Art is a concrete and personal and rather childish thing after all—no matter what people do to graft it into science and make it sociological and psychological; it is no good at all unless it is let alone to be itself—a game of make-believe, or re-production, very exciting and delightful to people who have an ear for it or an eye for it.”
—Willa Cather (1873–1947)
“All great movements are popular movements. They are the volcanic eruptions of human passions and emotions, stirred into activity by the ruthless Goddess of Distress or by the torch of the spoken word cast into the midst of the people.”
—Adolf Hitler (1889–1945)
