Special Issue Information
Dear Colleagues,
Evidence from animals and humans suggests that the visual representation of object properties (color, shape, texture, etc.) and spatial locations (where objects are in space, their relations and transformations) are subserved by two distinct pathways: the ventral visual pathway running from the occipital to the temporal lobes (the « what » pathway) and the dorsal visual pathway running from the occipital to the parietal lobes (the « where » pathway). These pathways are independent, but have reciprocal connections, which suggest that they may interact. The dorsal and ventral visual pathways are involved in visual mental imagery as well, although the overlap of deficits in visual perception and mental imagery is not always systematic. The involvment of the dorsal and ventral visual pathways in mental imagery, like in visual perception, has been demonstrated by studies of patients with brain lesions, functional brain imaging and purely behavioral studies in healthy participants. Research also appears to suggests a dissociation between object and spatial aphantasia or hyperphantasia. Through this callout, we would like to further our understanding of (1) the independence, communication or interdependence of the ventral and dorsal visual pathways in mental imagery; (2) the brain basis of visual mental imagery, especially but not exclusively, related to object properties mediated by the ventral visual pathway (as there are fewer studies, e.g., texture, etc.). We seek functional brain imaging studies in humans, studies of patients with brain lesions and of individuals with object or spatial aphantasia or hyperphantasia. We encourage, whenever possible, parallels to be drawn between visual perception and mental imagery. All paper formats (research studies, reviews, meta-analyses, etc.) are accepted.

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 250 words) can be sent to the Editorial Office for assessment.
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.
