Sexual Dimorphism and Age-Related Variations of Corpus Callosum Using Magnetic Resonance Imaging
Introduction: Despite technological advances and numerous published investigations, sexual dimorphism of Corpus Callosum (CC) remains a matter of ongoing controversy. In the present study on neurologically healthy Iranian adults, we investigated the possible gender- and age-related variations in anthropometric callosal measurements. Methods: Our sample comprised 35 male and 35 female sub...
متن کاملInterleukin-6, Age, and Corpus Callosum Integrity
The contribution of inflammation to deleterious aging outcomes is increasingly recognized; however, little is known about the complex relationship between interleukin-6 (IL-6) and brain structure, or how this association might change with increasing age. We examined the association between IL-6, white matter integrity, and cognition in 151 community dwelling older adults, and tested whether age...
متن کاملAgenesis of Corpus Callosum and Emotional Information Processing in Schizophrenia
Corpus callosum (CC) is essential in providing the integration of information related to perception and action within a subcortico-cortical network, thus supporting the generation of a unified experience about and reaction to changes in the environment. Its role in schizophrenia is yet to be fully elucidated, but there is accumulating evidence that there could be differences between patients an...
متن کاملRole of the corpus callosum in functional connectivity.
BACKGROUND AND PURPOSE Regional cerebral blood flow fluctuates synchronously in corresponding brain regions between the hemispheres. This synchrony implies neuronal connections between brain regions. The synchrony of blood flow changes is defined operationally as functional connectivity. Our purpose was to measure functional connectivity in patients with corpus callosal agenesis, in whom the in...
متن کاملEmotional arousal in agenesis of the corpus callosum.
While the processing of verbal and psychophysiological indices of emotional arousal have been investigated extensively in relation to the left and right cerebral hemispheres, it remains poorly understood how both hemispheres normally function together to generate emotional responses to stimuli. Drawing on a unique sample of nine high-functioning subjects with complete agenesis of the corpus cal...
