Hemispheric asymmetry (anatomical) Definition The concept refers to the fact that each cerebral hemisphere has unique functional characteristics and mediates different aspects of behavior.Measures of functional hemispheric asymmetry. Dichotic listening tests are regarded as noninvasive tools that yield valid estimates of hemispheric speech dominance (Geffen and Caudrey 1981; Hugdahl et al. 1997). After hearing impairments were excluded by audiometry, dichotic listening tests were performed in all subjects.In Hemispheric Lateralization Human brains tend to have shape asymmetry of the frontal and occipital lobes, called Hemispheric Lateralization Start studying Hemispheric Lateralization.

Methodology.The present paper is based on a talk on hemispheric asymmetry given by Kenneth Hugdahl at the Xth European Congress of Psychology, Praha July 2007. Here, we propose that hemispheric asymmetry evolved because of a left hemisphere speech processing specialization. asymmetry matches a corresponding functional asymmetry. The increase.Hemispheric specialization (HS) is a hemisphere-dependent relationship between a cognitive, sensory, or motor function and a set of brain structures. It includes both the hosting by a given hemisphere of specialized networks that have unique functional properties and mechanisms that enable the inter-hemispheric coordination necessary for efficient processing.Sep 28, 2017 Both hemispheres contribute to motor control beyond the the right hemisphere with the transformation of visual information to guide movements in space.
