Abstract : A summary is given of work done on the following topics: Fusion frequency for stimuli of alternating duration. A mathematical model for color constancy. An approach to computers that perceive, learn and reason. In search of the fundamental units of perception: an outline. Formation of cell assemblies. Mathematical models for neurone interaction. Model for conditioning and the effect of spaced tracts in learning. A canonical form for nerve nets without circles. A report on a study of visual adaptation is given. Principal results are a second order differential equation for the concentration of rhodopsin, a model that explains how the sensitivity of the rod depends on the concentration, a model that explains the shape of the b-wave of the electroretinogram, and the fitting of some data on illumination thresholds on the basis of these models.
