Human middle temporal cortex, perceptual bias, and perceptual memory for ambiguous three-dimensional motion.
When faced with inconclusive or conflicting visual input human observers experience one of multiple possible perceptions. One factor that determines perception of such an ambiguous stimulus is how the same stimulus was perceived on previous occasions, a phenomenon called perceptual memory. We examined perceptual memory of an ambiguous motion stimulus while applying transcranial magnetic stimula...
متن کاملConceptual and perceptual novelty effects in human medial temporal cortex.
Medial temporal lobe (MTL) structures often respond to stimulus repetition with a reduction in neural activity. Such novelty/familiarity responses reflect the mnemonic consequences of initial stimulus encounter, although the aspects of initial processing that lead to novelty/familiarity responses remain unspecified. The current functional magnetic resonance imaging (fMRI) experiment examined th...
متن کاملThe perceptual buildup of three-dimensional structure from motion.
We present a set of psychophysical experiments that measure the accuracy of perceived three-dimensional (3-D) structure derived from relative motion in the changing two-dimensional image. The experiments are motivated in part by a computational model proposed by Ullman (1984), called the incremental rigidity scheme, in which an accurate 3-D structure is built up incrementally, by considering im...
متن کاملTemporal Integration of Olfactory Perceptual Evidence in Human Orbitofrontal Cortex
Given a noisy sensory world, the nervous system integrates perceptual evidence over time to optimize decision-making. Neurophysiological accumulation of sensory information is well-documented in the animal visual system, but how such mechanisms are instantiated in the human brain remains poorly understood. Here we combined psychophysical techniques, drift-diffusion modeling, and functional magn...
متن کاملInvariant Temporal Dynamics Underlie Perceptual Stability in Human Visual Cortex
An inherent limitation of human visual system research stems from its reliance on highly controlled laboratory conditions. Visual processing in the real world differs substantially from such controlled conditions. In particular, during natural vision, we continuously sample the dynamic environment by variable eye movements that lead to inherent instability of the optical image. The neuronal mec...
