Function
The DLPFC plays a role in sustaining attention and working memory. Lesions to the DLPFC impair short-term memory and cause difficulty inhibiting responses. Lesions may also eliminate much of the ability to make judgements about what's relevant and what's not as well as causing problems in organization.
The DLPFC has recently been found to be involved in exhibiting self-control. http://sciencenow.sciencemag.org/cgi/content/full/2009/501/3
The dorsolateral prefrontal cortex is one of the few areas deactivated during REM sleep. Neuroscientist J. Allan Hobson has hypothesized that activation of the dorsolateral prefrontal cortex produces lucid dreams.

Famous quotes containing the word function:
“As a medium of exchange,... worrying regulates intimacy, and it is often an appropriate response to ordinary demands that begin to feel excessive. But from a modernized Freudian view, worrying—as a reflex response to demand—never puts the self or the objects of its interest into question, and that is precisely its function in psychic life. It domesticates self-doubt.”
—Adam Phillips, British child psychoanalyst. “Worrying and Its Discontents,” in On Kissing, Tickling, and Being Bored, p. 58, Harvard University Press (1993)
“It is the function of vice to keep virtue within reasonable bounds.”
—Samuel Butler (1835–1902)
““... The state’s one function is to give.
The bud must bloom till blowsy blown
Its petals loosen and are strown;
And that’s a fate it can’t evade
Unless ‘twould rather wilt than fade.””
—Robert Frost (1874–1963)
