Abstract: A phase difference observation apparatus includes a light source; an illumination guide to guide illumination light from the light source to an observation target object in a cell culture vessel; an optical imager to form an optical image of the observation target object on an image sensor; and a controller. The illumination guide includes a spatial modulator to change an intensity distribution of the illumination light; the controller contains intensity distribution correction information associating a position of the imaging guide with respect to the cell culture vessel with an intensity distribution of illumination light at the position of the optical imager; the controller acquires imaging system position information, which is the position of the optical imager; and the controller changes an intensity distribution of illumination light in the spatial modulator on the basis of the imaging system position information and the intensity distribution correction information.

Abstract: The present invention provides a method with which it is possible to directly induce nervous system cells efficiently and in a short amount of time. Because the method is easy to scale up and is not affected by the characteristics or background of the somatic cells used as material, the method enables the stable supply of nervous system cells. The nervous system cells obtained by the method are useful in various fields of research and healthcare.
