Special Issue Information

Dear Colleagues,

Posture and movement are essential features for carrying out our daily tasks. Both functions have been shown to influence various aspects of brain function, including neural connectivity, information processing, and cognitive performance. Although the human brain's intrinsic activity, often measured using functional magnetic resonance imaging (fMRI), has been extensively studied for many years, the influence of posture and movement on these intrinsic brain dynamics remains an area of active investigation with far-reaching implications. Understanding the relationship between posture, movement, and intrinsic brain activity is crucial for unraveling the complex interplay between the brain, body, and behavior. Posture refers to the alignment and orientation of the body in space, while movement encompasses a broad spectrum of activities ranging from fine motor control to gross locomotion. Here, we propose a Special Issue to bring together interdisciplinary research from neuroscience, psychology, biomechanics, rehabilitation sciences, and related fields to deepen our understanding of how posture and movement affect intrinsic brain activity. We welcome contributions that employ a wide range of methodologies, including neuroimaging techniques, behavioral assessments, computational modeling, and clinical studies.

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.

The temporoparietal junction (TPJ), which integrates visual, somatosensory, and vestibular information to form body schema, is involved in human postural control. We evaluated whether or not the transcranial direct current stimulation (tDCS) of the TPJ can modulate postural control on an unstable surface with eyes closed, during which the updating of body schema is needed to maintain balance. Sixteen healthy subjects participated in this study. The order of the three types of tDCS (anodal, cathodal, and sham) over the right TPJ was counterbalanced across the participants. We evaluated dynamic posture control while the participants were standing on a stable surface with eyes open and an unstable surface with eyes closed. Anodal tDCS enhanced postural control on an unstable surface with eyes closed during and after stimulation, but cathodal tDCS deteriorated postural control during stimulation. Neither anodal nor cathodal tDCS altered postural control while the participants were on a stable surface with eyes open. Anodal tDCS may enhance postural control with non-vision and altered tactile perception by activating the TPJ, which integrates multisensory inputs to update the body schema, whereas cathodal tDCS has the opposite effect. tDCS over the TPJ may facilitate the updating of body schemas to accommodate changes in sensory inputs and help develop novel approaches to prevent falls.
