Cerebral Asymmetry : Perception and Expression of Facial Emotions

This book defines the concept of cerebral/hemispheric asymmetry and emphasizes its multidisciplinary nature.It describes biological and functional hemispheric asymmetry and its importance in understating the overall nature of cerebral asymmetry. Drawing on recent empirical evidence, the book highlights different methods used to examine hemispheric asymmetry and the factors that influence it, such as handedness, gender, aging, and nature of task.With a neuropsychological perspective on emotions, it integrates three different approaches: specific population ( unilateral focal brain damaged patients and neurologically intact brain subjects), behavioural measures ( split field presentation, dichotic listening task and spatial tasks) and response measures ( speed and accuracy), along with physiological and neuroimaging techniques ( EEG, CT scan, PET Scan, MRI, and fMRI) to provide a more comprehensive understanding of hemispheric asymmetry in processing facial expressions of emotion.Furthermore, it highlights the clinical and theoretical significance of research in the said and the future direction of the research. This book would be useful to the students, researchers, and teachers from the fields of Neuropsychology, Neuroscience, Cognitive Neuroscience, Psychology, and Rehabilitation.The book would also prove to be an essential guide for policy makers.
