Decoding the Cortical Representation of Depth

Show Summary Details

Preview

This chapter reviews advances in elucidating functional specialization for depth processing by the human brain while recognizing the complexity of the problem. It starts by discussing the conceptual and methodological challenges faced when investigating the neural circuits that process depth signals. It then reviews evidence for the specialization of different cortical areas in processing individual depth cues. Finally, it discusses work examining the representation of 3D structure from a combination of signals. The tenet of the chapter is that linking functional magnetic resonance imaging recordings with psychophysical measurements provides a strong basis from which to test the cortical representation of 3D structure.

Keywords: functional specialization; depth processing; depth signals; depth cues; 3D structure; functional magnetic resonance imaging
