morphology in attention deficit-hyperactivity disorder: Morphometric analysis of MRI.
30) In this condition, T2-hyperintense WM lesions are characteristically present within the body of the corpus callosum
in addition to the subcortical WM, brainstem, and deep gray matter structures.
The acrocallosal syndrome comprises preaxial polysyndactyly, macrocephaly, agenesis of the corpus callosum
, mental retardation, seizures, and hernias (12).
Following GD 7 alcohol exposure, the researchers have found deficits in a number of major fiber tracts including the corpus callosum
and fimbria/fornix in their mouse model (see figure 5B and D).
As a Micro to Million Award recipient, Callosum
believes we can positively impact the results of dozens more companies and improve the lives and effectiveness of hundreds of currently under-utilized employees," said Clare Hefferren, President and Founder of Callosum
An additional illustration of the value of this intermodule perspective sharing is evident in individuals with the neurological condition called Agenesis of the Corpus Callosum
These included three cases of agenesis of the corpus callosum
, one case of interventricular hemorrhage, and one case of focal encephalomalacia.

Kim Peek, who suffered from a condition similar to autism - Agenesis of Corpus Callosum
- was thanked by Dustin Hoffman in his Best Actor acceptance speech, while film-writer Barry Morrow also acknowledged him.
Of these, the study identified corpus callosum
lesions in 84%.
Studies utilising DTI have identified sub-cortical white matter and corpus callosum
abnormalities in patients with HIV, despite normal-appearing white matter on MR and non-focal neurological examinations (20) (Fig.
Recently, more specific MR findings have been described, such as involvement of the anterior part of the temporal pole, the external capsule, and the corpus callosum
the role of the corpus callosum
in inter-hemispheric transfer of somatosensory information, aspects of memory, and the post- treatment status of patients with gliomas (the type of brain tumor that Senator Kennedy has).
: The corpus callosum
is the cluster of white matter that connects the right and left sides of the brain, enabling them to communicate
In addition to the extra flap of skin in her trachea, Ava was born with partial absence of the corpus callosum
, a rare birth defect in which the band of tissue connecting the two hemispheres of the brain do not develop normally.
