Different cortical dynamics in face and body perception: an MEG study. [PDF]

open access: yesPLoS ONE, 2013
Evidence from functional neuroimaging indicates that visual perception of human faces and bodies is carried out by distributed networks of face and body-sensitive areas in the occipito-temporal cortex.

Chromatic mechanisms in striate cortex of macaque [PDF]

open access: yesThe Journal of Neuroscience, 1990
We measured the responses of 305 neurons in striate cortex to moving sinusoidal gratings modulated in chromaticity and luminance about a fixed white point. Stimuli were represented in a 3-dimensional color space defined by 2 chromatic axes and a third along which luminance varied.

Gestalts at threshold could reveal Gestalts as predictions

open access: yesScientific Reports, 2021
We review and revisit the predictive processing inspired “Gestalts as predictions” hypothesis. The study of Gestalt phenomena at and below threshold can help clarify the role of higher-order object selective areas and feedback connections in mid-level ...

A simpler primate brain: the visual system of the marmoset monkey

open access: yesFrontiers in Neural Circuits, 2014
Humans are diurnal primates with high visual acuity at the centre of gaze. Although primates share many similarities in the organisation of their visual centres with other mammals, and even other species of vertebrates, their visual pathways also show ...

Paired Feed-Forward Excitation With Delayed Inhibition Allows High Frequency Computations Across Brain Regions

open access: yesFrontiers in Neural Circuits, 2022
The transmission of high frequency temporal information across brain regions is critical to perception, but the mechanisms underlying such transmission remain unclear.

Color contrast processing in human striate cortex [PDF]

open access: yesProceedings of the National Academy of Sciences, 2007
Color constancy refers to the unchanging nature of the perceived color of an object despite considerable variation in the wavelength composition of the light illuminating it. The color contrasts between objects and their backgrounds play a crucial role in color constancy.

Feeling happy enhances early spatial encoding of peripheral information automatically: electrophysiological time-course and neural sources. [PDF]

open access: yes, 2014
Previous research has shown that positive mood may broaden attention, although it remains unclear whether this effect has a perceptual or a postperceptual locus. In this study, we addressed this question using high-density event-related potential methods.

Pyramidal cells in V1 of African rodents are bigger more branched and more spiny than those in primates.

open access: yesFrontiers in Neuroanatomy, 2014
Pyramidal cells are characterised by markedly different sized dendritic trees, branching patterns and spine density across the cortical mantle. Moreover, pyramidal cells have been shown to differ in structure among homologous cortical areas in different ...

Investigating visual effects of a disgust nocebo with fMRI [PDF]

open access: yesJournal of Integrative Neuroscience, 2018
There is growing evidence that placebos are able to influence visual perception. A previous functional magnetic resonance imaging study on the processing of disgust images demonstrated that a “disgust placebo” (inert pill administered with the verbal ...

Concurrent investigation of global motion and form processing in amblyopia: an equivalent noise approach [PDF]

open access: yes, 2016
PURPOSE: Directly comparing the motion and form processing in neurologic disorders has remained difficult due to the limitations in the experimental stimulus.
