First described in the late 1970s in Purkinje fibers and sinoatrial myocytes, the cardiac pacemaker "funny" (If) current has been extensively characterized and its role in cardiac pacemaking has been investigated.

Famous quotes containing the words funny and/or current:
“Time rushes by and yet time is frozen. Funny how we get so exact about time at the end of life and at its beginning. She died at 6:08 or 3:46, we say, or the baby was born at 4:02. But in between we slosh through huge swatches of time—weeks, months, years, decades even.”
—Helen Prejean (b. 1940)
“If the current is right, one can drift to success.”
—Mason Cooley (b. 1927)
