The best example of an established lateralization is that of Broca's and Wernicke's areas, where both are often found exclusively on the left hemisphere. Function lateralization, such as semantics, intonation, accentuation, and prosody, has since been called into question and largely been found to have a neuronal basis in both hemispheres. [6]
Researchers recommend that the inside edge of any visual stimulus should be between 2.5° and 3° from central fixation [2] [5] Lateralized stimuli must also be presented very briefly, to eliminate the participant's ability to make an eye-movement toward the lateralized stimulus (which would result in the stimulus no longer being lateralized ...
In the mid-19th century scientists first began to make discoveries regarding lateralization of the brain, or differences in anatomy and corresponding function between the brain's two hemispheres. Franz Gall, a German anatomist, was the first to describe what is now known as the Doctrine of Cerebral Localization. Gall believed that, rather than ...
The functional gradients are continuous functions through the cortex describing a distributed specificity, so that, for a given sensory system, the specific gradient, of contralateral character, is maximum in the corresponding projection area and decreases in gradation towards more "central" zone and beyond so that the final decline reaches ...
The Yakovlevian torque is often thought to reflect the lateralization of specific functions in the brain. [ 25 ] The parcellation theory proposes that an increasing brain size can conserve coincidental contralateral organization, [ 27 ] but does not explain the optic chiasm, nor that most vertebrates have a rather small forebrain, especially ...
The contralateral organization involves both executive and sensory functions (e.g., a left-sided brain lesion may cause a right-sided hemiplegia). The contralateral organization is only present in vertebrates. A number of theories have been put forward to explain this phenomenon, but none are generally accepted. [1]
The visual system is the physiological basis of visual perception (the ability to detect and process light).The system detects, transduces and interprets information concerning light within the visible range to construct an image and build a mental model of the surrounding environment.
Emotional lateralization is the asymmetrical representation of emotional control and processing in the brain. There is evidence for the lateralization of other brain functions as well. Emotions are complex and involve a variety of physical and cognitive responses, many of which are not well understood. The general purpose of emotions is to ...
