Intrinsic cortical dynamics are thought to underlie trial-to-trial variability of visually evoked responses in animal models. Understanding their function in the context of sensory …
Primary sensory regions are believed to instantiate stable neural representations, yet a number of recent rodent studies suggest instead that representations drift over time. To test …
We tested how a stimulus gestalt, defined by the neuronal interaction between local and global features of a stimulus, is represented within human primary visual cortex (V1). We …
Visual imagery is mediated via top-down activation of visual cortex. Similar to stimulus- driven perception, the neural configurations associated with visual imagery are differentiated …
The visual system analyzes image properties across multiple spatial and temporal scales. Population receptive field (“pRF”) models have successfully characterized spatial …

Extensive psychophysical and computational work proposes that the perception of coherent and meaningful structures in natural images relies on neural processes that convert …
The classic view that neural populations in sensory cortices preferentially encode responses to incoming stimuli has been strongly challenged by recent experimental studies. Despite …

Two sensory neurons usually display trial-by-trial spike-count correlations given the repeated representations of a stimulus. The effects of such response correlations on …
While humans experience the visual environment in a panoramic 220 view, traditional functional MRI setups are limited to display images like postcards in the central 10–15 of the …
