Abstract
A method of in vitro cellular assay includes measuring an electrical activity of at least two cell populations in a plurality of cell populations that are disposed to be spaced apart from each other and connected to each other via a neurite, in which at least one of the at least two cell populations for which the electrical activity is measured is a cell population including at least one kind of neural cell, and the at least two cell populations each exhibit different electrical activity properties at a point when the electrical activity is measured.
