Special Issue Information
Dear Colleagues,
Brain lateralization refers to the major involvement of one hemisphere of the brain in certain cognitive functions. It first became an important research topic in the mid-19th century with the identification of the Broca's area and the dominant involvement of the left hemisphere in language processing. Later, work in spatial neglect, a cognitive disorder characterized by a failure to orient, attend, or represent one side of space, suggested that the right hemisphere may be dominant for spatial attention. With the advent of modern neuroscience methods, research has refined these conclusions, showing that the two hemispheres are, in fact, closely linked and work together in complex ways. Moreover, lateralization in adult brains is not fixed and unchangeable and modulations or shifts of hemispheric lateralization can be triggered, for example, by daily experiences, experimental factors, or by brain injury. One esoteric but intriguing question is the potential lateralization in the field of artificial intelligence (AI) and artificial neural networks. In AI, rather than demonstrating the traditional physical hemispheric lateralization, research may show built-in or emergent modularity, with specialized components for particular functions. While AI offers only an approximate model of the brain, it may help to explain patterns of behavior observed with brain injuries and serve as a test bed for the degree to which hemispheric lateralization is malleable following simulated injury and model retraining.
Thus, the focus of the current Special Issue is state-of-the-art research on human brain lateralization. Using modern neuroscience, artificial neural networks, and brain imaging methods, our aim is to revisit characteristics of brain lateralization, and its multiple roles in cognitive functions of both adult and pediatric populations.

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.

Title: Dual representation of the auditory space: contribution of early stage auditory areas
Author: Clarke
Highlights: - - Auditory spatial cues contribute to: i) explicit localization of sounds and ii) position-linked representation of sound objects
- Activation and lesion studies demonstrated right-hemispheric lateralization for explicit sound localization
- AEP, fMRI and lesion studies revealed left- hemispheric lateralization for implicit, position-linked sound representation
- Differential encoding of explicit vs. implicit auditory-space representations occurs within early-stage auditory areas
