[HTML][HTML] Representations in human primary visual cortex drift over time

ZN Roth, EP Merriam - Nature Communications, 2023 - nature.com
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 …

The global configuration of visual stimuli alters co-fluctuations of cross-hemispheric human brain activity

S Nasr, D Kleinfeld, JR Polimeni - Journal of Neuroscience, 2021 - Soc Neuroscience
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 …

Top-down activation of shape-specific population codes in visual cortex during mental imagery

M Stokes, R Thompson, R Cusack… - Journal of …, 2009 - Soc Neuroscience
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 …

[HTML][HTML] Differential encoding of temporal context and expectation under representational drift across hierarchically connected areas

DG Wyrick, N Cain, RS Larsen, J Lecoq, M Valley… - bioRxiv, 2023 - ncbi.nlm.nih.gov

Representational geometries reveal differential effects of response correlations on population codes in neurophysiology and functional magnetic resonance imaging

ZJ Cheng, L Yang, WH Zhang… - Journal of …, 2023 - Soc Neuroscience
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 …

[HTML][HTML] Immersive scene representation in human visual cortex with ultra-wide angle neuroimaging
