Another study led by Shanghai-based East China Normal University's Department of Physics, "The Corpus Callosum of Albert Einstein's Brain: Another Clue to His High Intelligence", published in the journal Brain on September 24, 2013, showed a new technique to conduct the study, which is the first to detail Einstein's corpus callosum, the brain's ...
Sandra Freedman Witelson is a Canadian neuroscientist best known for her analysis of specimens from Albert Einstein's brain, as well as exploring anatomic and functional differences regarding male and female brains, handedness, and sexual orientation. [1]
The inability of these axons to cross the midline results in anomalous axonal guidance and front-to-back projections within each hemisphere, rather than connecting between the hemispheres in the normal corpus callosum. These longitudinal callosal fascicles were originally described by Moriz Probst in 1901 by gross anatomical observation. [1]
The corpus callosum is essential to the communication between the two hemispheres. [2] A recent study of individuals with agenesis of the corpus callosum suggests that the corpus callosum plays a vital role in problem solving strategies, verbal processing speed, and executive performance. Specifically, the absence of a fully developed corpus ...
The corpus callosum (Latin for "tough body"), also callosal commissure, is a wide, thick nerve tract, consisting of a flat bundle of commissural fibers, beneath the cerebral cortex in the brain. The corpus callosum is only found in placental mammals . [ 1 ]
The retrosplenial cortex (RSC) is a cortical area in the brain comprising Brodmann areas 29 and 30. [1] It is secondary association cortex, making connections with numerous other brain regions. The region's name refers to its anatomical location immediately behind the splenium of the corpus callosum in primates, although in rodents it is ...
Callosal syndrome, or split-brain, is an example of a disconnection syndrome from damage to the corpus callosum between the two hemispheres of the brain. Disconnection syndrome can also lead to aphasia , left-sided apraxia , and tactile aphasia, among other symptoms.
The procedure of surgically removing the corpus callosum is called a corpus callosotomy. Patients who have undergone a corpus callosotomy are colloquially referred to as "split-brain patients". They are called so because now their brain's left and right hemispheres are no longer connected by the corpus callosum. [citation needed]
