White-headed Vultures Trigonoceps occipitalis show visual field characteristics of hunting raptors [PDF]
, 2017 The visual fields of Aegypiinae vultures have been shown to be adapted primarily to meet two key perceptual challenges of their obligate carrion-feeding behaviour: scanning the ground and preventing the sun’s image falling upon the retina.

Earlier visual N1 latencies in expert video-game players: a temporal basis of enhanced visuospatial performance. [PDF]
, 2013 Increasing behavioural evidence suggests that expert video game players (VGPs) show enhanced visual attention and visuospatial abilities, but what underlies these enhancements remains unclear.

The cognitive neuroscience of visual working memory [PDF]
, 2017 Visual working memory allows us to temporarily maintain and manipulate visual information in order to solve a task. The study of the brain mechanisms underlying this function began more than half a century ago, with Scoville and Milner’s (1957) seminal ...

Lightness constancy: ratio invariance and luminance profile [PDF]
, 2009 The term simultaneous lightness constancy describes the capacity of the visual system to perceive equal reflecting surfaces as having the same lightness despite lying in different illumination fields.

Are v1 simple cells optimized for visual occlusions? : A comparative study [PDF]
, 2013 : Simple cells in primary visual cortex were famously found to respond to low-level image components such as edges. Sparse coding and independent component analysis (ICA) emerged as the standard computational models for simple cell coding because they ...

Gaze-contingent flicker pupil perimetry detects scotomas in patients with cerebral visual impairments or glaucoma [PDF]
, 2018 The pupillary light reflex is weaker for stimuli presented inside as compared to outside absolute scotomas. Pupillograph perimetry could thus be an objective measure of impaired visual processing.

Does Corticothalamic Feedback Control Cortical Velocity Tuning? [PDF]
, 2001 The thalamus is the major gate to the cortex and its contribution to cortical receptive field properties is well established. Cortical feedback to the thalamus is, in turn, the anatomically dominant input to relay cells, yet its influence on thalamic ...

The Computational Magic of the Ventral Stream: Towards a Theory [PDF]
, 2011 I conjecture that the sample complexity of object recognition is mostly due to geometric image transformations and that a main goal of the ventral stream – V1, V2, V4 and IT – is to learn-and-discount image transformations.

Creating new stories for praxis: navigations, narrations, neonarratives [PDF]
, 2007 This paper considers differing understandings about the role and praxis of studio-based research in the visual arts. This is my attempt to unpack this nexus and place it in a context of credibility for our field.

Multi-field visualization [PDF]
, 2011 Modern science utilizes advanced measurement and simulation techniques to analyze phenomena from fields such as medicine, physics, or mechanics. The data produced by application of these techniques takes the form of multi-dimensional functions or fields, which have to be processed in order to provide meaningful parts of the data to domain experts ...
