Special Issue Information

Dear Colleagues,

Brain asymmetry is a topic of great interest in cognitive neuroscience. Structural and functional symmetries are characteristic of biology and nature. However, how the human brain works symmetrically and asymmetrically is yet to be determined. Several studies have proven asymmetry in cognitive and behavioral functions such as visual perception, auditory perception, attention, emotion, and language, among many others.

The purpose of this Special Issue is to study how the brain hemispheres are related and organized to approach cognitive perception and behavior in terms of asymmetry, and to investigate the symmetry and asymmetry of the brain in cognitive and behavioral processes.

We welcome papers studying electrophysiology, neuroimaging techniques, and behavioral analyses.

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. Symmetry 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 2400 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 way audiovisuals are perceived is not completely understood. Previous works have shown that attention increases when watching audiovisuals compared with looking at real events, but depending on the editing style, and the interpreter, the understanding of the content may be different. The study of brain asymmetries in this context aims to identify potential lateralizations in audiovisual perception. Previous studies have proven that seeing others grasp objects has a contralateral impact on somatosensory areas (C3 and C4) in the alpha band (8–12 Hz). In this work, we investigated whether brain activity could be asymmetrical in that band when looking at real grasping compared with watching grasping on a screen, and whether media expertise would be a determinant in this regard and presented the same narrative content both through live performance and as a movie to 40 participants (half of them media professionals) while recording their electroencephalography (EEG) activity. We conclude that the asymmetry in the alpha band in the somatosensory cortex is not affected by the medium through which the grasping actions are presented, that is, in reality or on screen. We also conclude that media expertise does not impact this asymmetry. Full article

Prefrontal cortex activity facilitates emotion regulation by cognitive reappraisal. Yet, neuroimaging studies have yielded disparate findings as to whether relatively greater left or right prefrontal activity is more beneficial for reappraisal success. We argue that differences in hemispheric activation during reappraisal efforts may depend on the specific and diverse cognitive strategies utilized to reappraise negative stimuli. In this EEG study, n = 94 participants were randomly assigned to three groups and instructed to either generate problem-oriented reappraisals, positive reinterpretations, or distancing reappraisals for anger-eliciting situations while EEG alpha asymmetry changes in the prefrontal cortex were recorded (F3–F4, F7–F8, and Fp1–Fp2). Engaging in problem orientation yielded a right-lateralized frontal activation pattern and was linked to the highest reappraisal success (percentage of strategy-conforming reappraisals), along with the highest believability ratings. Conversely, engaging in distancing reappraisal yielded a left-lateralized frontal EEG pattern, along with the highest ideational fluency and lowest anger ratings post-reappraisal. No distinct asymmetry pattern emerged for positive reinterpretation; however, this reappraisal condition yielded the lowest reappraisal success and lowest believability ratings. For all groups, higher reappraisal capacity correlated with right-lateralized frontal activity. Frontal EEG alpha asymmetry observed during reappraisal may be a specific function of implemented reappraisal strategy rather than general ideational fluency. Full article
