| | Current research in the Purves laboratory concerns visual and auditory perception and the neurobiological underpinnings of perceptual phenomena. Ongoing investigations in vision include understanding the perception of brightness, color, orientation, motion, and depth; the phenomena of interest in audition are pitch, loudness, and tonal relationships in music and speech. The unifying theme of these several projects is the hypothesis that visual and auditory percepts are generated according to a wholly empirical strategy, which represents in perception the empirical significance of a stimulus rather than its physical properties. This theory of perception and its relation to cortical structure and function is being explored by examining the perceptual responses of human subjects in relation to natural image and sound databases, the emerging properties of virtual organisms that evolve in defined environments, and the response properties of visual cortical neurons in experimental animals. In general, this work is focused on validating the idea that perceptual phenomenology is always accurately predicted by the statistical information in databases that serve as proxies of human experience.
