Partial agenesis of the corpus callosum in spina bifida meningomyelocele and potential compensatory mechanisms

Partial agenesis of the corpus callosum in spina bifida meningomyelocele and potential compensatory mechanisms.

After a review of Arthur Benton's conceptual and methodological contributions to the understanding of normal and pathological development, we discuss agenesis of the corpus callosum (CC), criteria for potential neuroanatomical compensatory mechanisms in CC agenesis, and the results of an examination of magnetic resonance imaging (MRI) data of the CC in 193 children with spina bifida meningomyel...

Auditory interhemispheric transfer in relation to patterns of partial agenesis and hypoplasia of the corpus callosum in spina bifida meningomyelocele.

Spina bifida meningomyelocele with hydrocephalus (SBM) is commonly associated with anomalies of the corpus callosum (CC). We describe MRI patterns of regional CC agenesis and relate CC anomalies to functional laterality based on a dichotic listening test in 90 children with SBM and 27 typically developing controls. Many children with SBM (n = 40) showed regional CC anomalies in the form of agen...

The cognitive phenotype of spina bifida meningomyelocele.

A cognitive phenotype is a product of both assets and deficits that specifies what individuals with spina bifida meningomyelocele (SBM) can and cannot do and why they can or cannot do it. In this article, we review the cognitive phenotype of SBM and describe the processing assets and deficits that cut within and across content domains, sensory modality, and material, including studies from our ...

Agenesis of the Corpus Callosum

Agenesis of the Corpus Callosum

COMPLETE or partial agenesis of the corpus callosum is uncommon especially in adults; the incidence amongst patients in institutions where numerous air encephalograms are performed is 3% (Carpenter and Drukemiller, 1953). Reil (1812) published the first report of a case, describing the necropsy findings in a 30 year old woman of low mentality; further cases discovered at necropsy were subsequen...
