In mammals, the suprachiasmatic nucleus (SCN) contains a biological clock that drives circadian rhythms in vivo and in vitro. Primary dissociated neuronal culture is a useful research tool, which allows cell-by-cell morphological and physiological study of the SCN. A long-term primary dissociated SCN neuron culture is the prerequisite to understanding how neural activity and morphology interact in the SCN. The essential details of recent effective SCN culture methods are reviewed, including preparation of cells, medium and substrate, maintenance of cultures, and characterization of cultured SCN neurons. This technique is growing in importance, especially with the advent of multi-electrode array (MEA) recording.
