From Pigments to Perception: Advances in Understanding the Visual Process - Workshop Proceedings: 203 (NATO Science Series A: Life Sciences)

Considers the processes and problems involved in multidisciplinary approaches to vision, focusing not only on detection tasks involving correlations between visual thresholds and cellular sensitivities, but also on the current status of "neuron doctrines", and the relationships to be found between sensations and supra-threshold neuronal processes (thus the area of interaction between psychophysics and physiology).
