Special Issue Information

Dear Colleagues,

Affective (emotional) prosody and facial expressions have been active areas of research that have attracted increasing attention from investigators in behavioral neurology, neuropsychiatry, neuropsychology, neurophysiology, computer science, neurolinguistics, and related disciplines. Emotional expressions are one of the most widely studied topics in neuroscience, from both clinical and non-clinical perspectives.

Disorders of emotional expression occur in a variety of neurological and neuropsychiatric conditions. Focal brain lesions may result in pathological regulation of affect (involuntary crying or laughing) or loss of affective prosody and/or loss of facial expressions. Flattening of affect may be observed in neurodegenerative disorders, such as Parkinson disease and fronto-temporal dementia, and as part of the right hemisphere developmental syndrome. Flattening of affect is also a cardinal symptom of schizophrenia and alexithymia. Depressive affect and manic behaviors are characteristic of affective disorders.

This Special Issue invites expert manuscripts that focus on disorders of emotional expression involving facial expressions and affective prosody that are associated with focal brain damage, neurodegenerative disorders (Parkinson disease and dementing illnesses), neurodevelopmental disorders, manic-depressive states, schizophrenia, and alexithymia.

We look forward to receiving your contributions, both qualitative and quantitative, regarding the disorder of emotional expression. Systematic reviews and meta-analyses will also be considered for inclusion.

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.

Based on the seminal publications of Paul Broca and Carl Wernicke who established that aphasic syndromes (disorders of the verbal–linguistic aspects of communication) were predominantly the result of focal left-hemisphere lesions, “language” is traditionally viewed as a lateralized function of the left hemisphere. This, in turn, has diminished and delayed the acceptance that the right hemisphere also has a vital role in language, specifically in modulating affective prosody, which is essential for communication competency and psychosocial well-being. Focal lesions of the right hemisphere may result in disorders of affective prosody (aprosodic syndromes) that are functionally and anatomically analogous to the aphasic syndromes that occur following focal left-hemisphere lesions. This paper will review the deductive research published over the last four decades that has elucidated the neurology of affective prosody which, in turn, has led to a more complete and nuanced understanding of the neurology of language, depression, emotions and memory. In addition, the paper will also present the serendipitous clinical observations (inductive research) and fortuitous inter-disciplinary collaborations that were crucial in guiding and developing the deductive research processes that culminated in the concept that primary emotions and related display behaviors are a lateralized function of the right hemisphere and social emotions, and related display behaviors are a lateralized function of the left hemisphere.
