Space and time in visual context
O Schwartz, A Hsu, P Dayan - Nature Reviews Neuroscience, 2007 - nature.com
No sensory stimulus is an island unto itself; rather, it can only properly be interpreted in light
of the stimuli that surround it in space and time. This can result in entertaining illusions and …

Efficient coding and the neural representation of value
K Louie, PW Glimcher - Annals of the New York Academy of …, 2012 - Wiley Online Library
To survive in a dynamic environment, an organism must be able to effectively learn, store,
and recall the expected benefits and costs of potential actions. The nature of the valuation …

Attractive serial dependence overcomes repulsive neuronal adaptation
TC Sheehan, JT Serences - PLoS biology, 2022 - journals.plos.org
Sensory responses and behavior are strongly shaped by stimulus history. For example,
perceptual reports are sometimes biased toward previously viewed stimuli (serial …

A Bayesian and efficient observer model explains concurrent attractive and repulsive history biases in visual perception
Human perceptual decisions can be repelled away from (repulsive adaptation) or attracted
towards recent visual experience (attractive serial dependence). It is currently unclear …

Chunking as a rational strategy for lossy data compression in visual working memory.
The nature of capacity limits for visual working memory has been the subject of an intense
debate that has relied on models that assume items are encoded independently. Here we …

Visual nonclassical receptive field effects emerge from sparse coding in a dynamical system
M Zhu, CJ Rozell - PLoS computational biology, 2013 - journals.plos.org
Extensive electrophysiology studies have shown that many V1 simple cells have nonlinear
response properties to stimuli within their classical receptive field (CRF) and receive …

Adaptation across the cortical hierarchy: Low-level curve adaptation affects high-level facial-expression judgments
Adaptation is ubiquitous in sensory processing. Although sensory processing is hierarchical,

More gamma more predictions: gamma-synchronization as a key mechanism for efficient integration of classical receptive field inputs with surround predictions
During visual stimulation, neurons in visual cortex often exhibit rhythmic and synchronous
firing in the gamma-frequency (30–90 Hz) band. Whether this phenomenon plays a …

Perceptual organization in the tilt illusion
O Schwartz, TJ Sejnowski, P Dayan - Journal of Vision, 2009 - jov.arvojournals.org
The tilt illusion is a paradigmatic example of contextual influences on perception. We
analyze it in terms of a neural population model for the perceptual organization of visual …
