Functions
The section "Areas of Electrical Coupling" reflects the circumstances of earliest discovery of gap junctions and their function in allowing the transmission electrical impulses among cells at levels that elicit responses from their neighboring cells. The transmission of a nerve impulse and the contraction of muscle are relatively easily detected and quantified experimentally. "Areas of Electrical Coupling" also touches upon the retinal gap junctions which could be seen as specialist nerve cells. Many new functions for gap junctions have been uncovered since those early years.

Famous quotes containing the word functions:
“When Western people train the mind, the focus is generally on the left hemisphere of the cortex, which is the portion of the brain that is concerned with words and numbers. We enhance the logical, bounded, linear functions of the mind. In the East, exercises of this sort are for the purpose of getting in tune with the unconscious—to get rid of boundaries, not to create them.”
—Edward T. Hall (b. 1914)
“In today’s world parents find themselves at the mercy of a society which imposes pressures and priorities that allow neither time nor place for meaningful activities and relations between children and adults, which downgrade the role of parents and the functions of parenthood, and which prevent the parent from doing things he wants to do as a guide, friend, and companion to his children.”
—Urie Bronfenbrenner (b. 1917)
“If photography is allowed to stand in for art in some of its functions it will soon supplant or corrupt it completely thanks to the natural support it will find in the stupidity of the multitude. It must return to its real task, which is to be the servant of the sciences and the arts, but the very humble servant, like printing and shorthand which have neither created nor supplanted literature.”
—Charles Baudelaire (1821–1867)
