Less Is More: Expectation Sharpens Representations in the Primary Visual Cortex
Prior expectations about the visual world facilitate perception by allowing us to quickly deduce plausible interpretations from noisy and ambiguous data. The neural mechanisms of this facilitationExpand

Attention reverses the effect of prediction in silencing sensory signals.
Predictive coding models suggest that predicted sensory signals are attenuated (silencing of prediction error). These models, though influential, are challenged by the fact that prediction sometimesExpand

Perceptual Learning Selectively Refines Orientation Representations in Early Visual Cortex
Although practice has long been known to improve perceptual performance, the neural basis of this improvement in humans remains unclear. Using fMRI in conjunction with a novel signal detection-basedExpand

Reinstatement of Associative Memories in Early Visual Cortex Is Signaled by the Hippocampus
The cortical reinstatement hypothesis of memory retrieval posits that content-specific cortical activity at encoding is reinstated at retrieval. Evidence for cortical reinstatement was found inExpand

Attention Improves Encoding of Task-Relevant Features in the Human Visual Cortex
When spatial attention is directed toward a particular stimulus, increased activity is commonly observed in corresponding locations of the visual cortex. Does this attentional increase in activityExpand

Sensory uncertainty decoded from visual cortex predicts behavior
Bayesian theories of neural coding propose that sensory uncertainty is represented by a probability distribution encoded in neural population activity, but direct neural evidence supporting thisExpand

Predictive Feedback Can Account for Biphasic Responses in the Lateral Geniculate Nucleus
TLDR
Biphasic neural response properties, where the optimal stimulus for driving a neural response changes from one stimulus pattern to the opposite stimulus pattern over short periods of time, have been described in several visual areas, including lateral geniculate nucleus (LGN), primary visual cortex (V1), and middle temporal area.

Boundary assignment in a recurrent network architecture
TLDR
We describe a model and simulations of boundary assignment by cortical neurons, a process that assigns edges to figural image regions, as opposed to the background regions on the other side. Expand

Probabilistic representation in human visual cortex reflects uncertainty in serial decisions
TLDR
We probe the neural representation of uncertainty by capitalizing on a well-known behavioral bias called serial dependence. Expand
