Representing the World
Representing the World
This chapter explores the neurobiology of representations, and more specifically how nervous systems represent in the occurrent sense. It first provides an overview of the basic anatomy and physiology of the mammalian visual system before discussing how neurons encode information by drawing on the comparison between “grandmother” coding and distributed coding. In particular, it considers vector coding vs. local coding and the conceptual fecundity of “state space,” along with the question of whether nervous systems honor at all the distinction between vectors of activation and matrices for processing. The chapter proceeds by analyzing the shape-from-shading model, computational models of stereo vision, hyperacuity, and vector averaging.
Keywords: neurobiology, nervous systems, mammalian visual system, neurons, vector coding, local coding, shape-from-shading model, stereo vision, hyperacuity, vector averaging
