CHARACTERISING REPRESENTATIONS OF HUE AND SATURATION IN THE CORTEX USING INFORMATION DECODING

This study decodes EEG signals to characterize how hue and saturation are represented in the cortex, finding that maximally dissimilar hues evoke similar signals and that decoding performance varies with saturation.

Decoding of EEG signals reveals non-uniformities in the neural geometry of colour

The paper uses EEG decoding to show that unique hues elicit distinct neural activity patterns, revealing non-uniformities in the neural geometry of color perception.

Sub-optimality of the early visual system explained through biologically plausible plasticity

The paper explains sub-optimality in early visual cortex receptive fields through biologically plausible plasticity mechanisms, showing better alignment with biological data than global optimisation models.

Stimulation-specific information is represented as local activity patterns across the brain

The paper shows that brain activity patterns are spatially correlated and represent stimulation-specific information in localized regions.

Simultaneous mental updating in physical space and number space

The paper tests whether a common rate control module can pace simultaneous mental updating in physical space and number space, finding no dual task interference.

Emergence of binocular disparity selectivity through Hebbian learning

This paper shows how Hebbian learning can generate binocular disparity-selective receptive fields in a model of early visual cortex.
