Sound localization in callosal agenesis and early callosotomy subjects: brain reorganization and/or compensatory strategies.
In order to evaluate the callosal involvement in sound localization, the present study examined the response accuracy of acallosal and early callosotomized subjects to monaural and binaural auditory targets presented in three-dimensional space. In these subjects, bilateral localization cues, such as interaural time and level differences, are integrated at the cortical and subcortical levels wit...
متن کاملSound lateralization in subjects with callosotomy, callosal agenesis, or hemispherectomy.
The question of whether there is a right-hemisphere dominance in the processing of auditory spatial information in human cortex as well as the role of the corpus callosum in spatial hearing functions is still a matter of debate. Here, we approached this issue by investigating two late-callosotomized subjects and one subject with agenesis of the corpus callosum, using a task of sound lateralizat...
متن کاملNeuropsychological studies of callosal agenesis
A developmental error or arrest during the foetal growth of the telencephalic midline can lead to partial or complete agenesis of the corpus callosum. A person who is born with no corpus callosum at all is likely also to lack the hippocampal commissure, but unlikely to lack the anterior commissure (Loeser & Alvord, 1968 a). Indeed, some congenitally acallosal individuals appear to have an enlar...

متن کاملCompensatory plasticity and cross-modal reorganization following early visual deprivation.
For human and non-human primates, vision is one of the most privileged sensory channels used to interact with the environment. The importance of vision is strongly embedded in the organization of the primate brain as about one third of its cortical surface is involved in visual functions. It is therefore not surprising that the absence of vision from birth, or the loss of vision later in life, ...
