Dear Colleagues,

Our understanding of visual–spatial functions has increased significantly in recent decades. Advances in classic areas such as visual acuity, sensitivity to luminance contrast, and Vernier acuity—whether or not applied to developmental diseases such as Amblyopia and Visual Processing Disorders—have been significant for a deeper understanding of the underlying mechanisms of these functions, as well as the functional impacts in these atypical developmental conditions. Other intriguing areas of visual–spatial processing, such as second-order contrast sensitivity, spatial texture perception, orientation, and spatial locations, are also expanding knowledge of the visual processing of perceptual and cognitive orders. The relationship between memory and attention with the spatial processing of vision is also a topic of major recent advances. Of late, we have dedicated ourselves to the study of sensory and perceptual spatial functions, both to identify basic mechanisms and to develop diagnostic methodologies and interventions for these complex visual functions. This Special Issue aims to gther together studies that are at the frontier of the scientific development of these visual functions.

The scope of this Special Issue on Advances in Spatial Vision and Visual Perception covers original research studies and literature reviews, integrative or systematic, that present the results of new research contributing to knowledge on the mechanisms of spatial vision and spatial and visual perception. Articles that present new diagnostic or intervention methodologies for visual–spatial functions and visual perception are also welcome. This includes sensory, low- and high-level perceptual aspects and visual–spatial cognitive functions such as spatial attention and memory.

Innovative research in this area includes methodological innovations, with the development of psychophysical, electrophysiological, and imaging measures, which bring innovative contributions and use advanced research and investigation tools. However, there is no thematic or approach restriction if advances in spatial vision and related aspects visual perception are a central part of the work.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Brain Sciences is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2200 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
