Posterior cortical atrophy as a variant of progressive local brain atrophy
Анналы клинической и экспериментальной неврологии, 2017 Posterior cortical atrophy (PCA) is a rare disease that manifestsmainly as disturbance of cortical visual function, agnosia.Blints syndrome (optic ataxia) is one of the clearest clinicalmarkers of the disease.

Fixation and saliency during search of natural scenes: The case of visual agnosia
, 2009 Models of eye movement control in natural scenes often distinguish between stimulus-driven processes (which guide the eyes to visually salient regions) and those based on task and object knowledge (which depend on expectations or identification of ...

Developmental prosopagnosia and adaptative compensatory strategies: Case study
Dementia & NeuropsychologiaProsopagnosia is a type of visual agnosia with inability to identify faces, usually secondary to brain lesion in associative cortex areas, but there is also a congenital form known as developmental prosopagnosia.

Connecting art and the brain: an artist’s perspective on visual indeterminacy
Frontiers in Human Neuroscience, 2011 In this article I will discuss the intersection between art and neuroscience from the perspective of a practicing artist. I have collaborated on several scientific studies into the effects of art on the brain and behaviour, looking in particular at the ...

"Mirror agnosia" in a patient with right occipitotemporal infarct
Annals of Indian Academy of Neurology, 2006 We report the clinical profile and investigation of K, a patient suffering from agnosia for the concept of "mirrors". Normal people rarely confuse a mirror image for the real image.

Lateralized occipital degeneration in posterior cortical atrophy predicts visual field deficits
NeuroImage: Clinical, 2017 Background: Posterior cortical atrophy (PCA), the visual variant of Alzheimer's disease, leads to high-level visual deficits such as alexia or agnosia. Visual field deficits have also been identified, but often inconsistently reported.

Frontiers in Psychology, 2013 The proposed model holds that, at its most fundamental level, visual awareness is quantized. That is to say that visual awareness arises as individual bits of awareness through the action of neural circuits with hundreds to thousands of neurons in at ...
