Abstract: A method of monitoring a body tissue includes determining, with reference to a position of an m-th light emitting unit, a position of an n-th light reception unit, and a distance between the m-th light emitting unit and the n-th light reception unit, an area and a depth of the body tissue which corresponds to the m-th light emitting unit and the n-th light reception unit; measuring hemodynamics of the body tissue at the area and the depth corresponding to the m-th light emitting unit and the n-th light reception unit based on the optical signal generated from the m-th light emitting unit and detected by the n-th light reception unit; and estimating an activity of the body tissue on an area basis and a depth basis based on the hemodynamics at at least one of the area and the depth of the body tissue.
