The Bayesian‐Laplacian brain

S Zeki, OY Chén - European Journal of Neuroscience, 2020 - Wiley Online Library
We outline what we believe could be an improvement in future discussions of the brain
acting as a Bayesian‐Laplacian system. We do so by distinguishing between two broad …

[HTML][HTML] The biological basis of mathematical beauty

S Zeki, OY Chén, JP Romaya - Frontiers in human neuroscience, 2018 - frontiersin.org
Our past studies have led us to divide sensory experiences, including aesthetic ones
derived from sensory sources, into two broad categories: biological and artifactual. The …

Light adaptation of retinal rods, adaptation memory, and afterimages

AY Rotov, LA Astakhova, ML Firsov… - Neuroscience and …, 2021 - Springer
The GPCR signal cascade in retinal photoreceptor cells–rods and cones–supports powerful
signal amplification and allows rods to respond reliably to single light quanta. Rods remain …

The biological basis of the experience and categorization of colour

S Zeki, A Javier, D Mylonas - European Journal of …, 2020 - Wiley Online Library
Abstract We used the Land Colour Mondrian experiments in a Bayesian context to test the
degree to which subjects vary in categorizing the colour of different patches, when each …

[HTML][HTML] Contents of Unconscious Color Perception

B Skrzypulec - Review of Philosophy and Psychology, 2022 - Springer
In the contemporary discussions concerning unconscious perception it is not uncommon to
postulate that content and phenomenal character are 'orthogonal', ie, there is no type of …

[HTML][HTML] A Model for a filling-in process triggered by edges predicts “Conflicting” afterimage effects

H Cohen-Duwek, H Spitzer - Frontiers in Neuroscience, 2018 - frontiersin.org
The goal of our research was to develop a compound computational model that predicts the
“opposite” effects of the alternating aftereffects stimuli, such as the “color dove …

[HTML][HTML] Chromatic adaptation from achromatic stimuli with implied color

RJ Lee, G Mather - Attention, Perception, & Psychophysics, 2019 - Springer
Previous research has shown that the typical or memory color of an object is perceived in
images of that object, even when the image is achromatic. We performed an experiment to …
