Beats (1st version)
A heart consists of million of cells, most of which beat in unison at a rate of 50 to 120 beats per minute. Heart cells consists of myocytes who beat and fibroblasts who do not beat. The motions of the fibroblasts are visualized by stop-motion microcinematography.
A culture of heart cells of rats is observed. At the beginning, myocytes are scattered, then after one or two weeks, they are grouped together and beat synchronously. This regrouping of myocytes, forming homogeneous cells areas, is the consequence of the action of the fibroblasts. In these areas of contiguous cells, intacellular communication allows the myocytes to synchronise with each other.
