Insulin oscillation oscillations. The insulin oscillations are generated by pulsatile release of the hormone from the pancreas. Insulin originates from beta cells located in the islets of Langerhans. Since each islet contains up to 2000 beta cells and there are one million islets in the pancreas it is apparent that pulsatile secretion requires sophisticated synchronization both within and among the islets of Langerhans. Pulsatile insulin secretion from individual beta cells is driven by oscillation of the calcium concentration in the cells. In beta cells lacking contact, the periodicity of these oscillations is rather variable (2-10 min). However, within an islet of Langerhans
Adrift Just Off the Islets of Langerhans referred to the tale as "one of (Ellison's) most ambitious and provocative tales to date." Adrift Just Off the Islets of Langerhans "Adrift Just Off the Islets of Langerhans: Latitude 38° 54' N, Longitude 77° 00' 13" W" is an award-winning 1974 science fiction novelette by Harlan Ellison. It was originally published in "The Magazine of Fantasy & Science Fiction" in October 1974, and subsequently republished in Ellison's 1975 anthology "Deathbird Stories", in the 1991 Byron Preiss-edited anthology "The Ultimate Werewolf", and in Ellison's 2006 anthology "The Essential Ellison: A 50 Year Retrospective".
