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 ...
The lateral sulcus (Sylvian fissure) in a normal brain. In Einstein's brain, this was truncated. Witelson came into possession of three portions of Albert Einstein's brain after being contacted by Dr. Thomas Stoltz Harvey, the pathologist at the hospital where Einstein died. In 1955, he took the brain and, after preserving, photographing, and ...
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 (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 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 indusium griseum, (supracallosal gyrus, gyrus epicallosus) consists of a thin membranous layer of grey matter in contact with the upper surface of the corpus callosum and continuous laterally with the grey matter of the cingulate cortex and inferiorly with the hippocampus. It is vestigial in humans and is a remnant of the former position of ...
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]
Split-brain or callosal syndrome is a type of disconnection syndrome when the corpus callosum connecting the two hemispheres of the brain is severed to some degree. It is an association of symptoms produced by disruption of, or interference with, the connection between the hemispheres of the brain.
