Different types of damage to the corpus callosum cause different symptoms; however, all types of damage to the corpus callosum cause a disconnection between the brain's hemispheres, according to the National Institutes of Health. The corpus callosum is a part of the brain that connects the left and right hemispheres.
Dr. Jeffry Ricker cites a case in which a police officer suffered from a brain tumor located in the middle of the brain. Upon removal of the tumor, it was discovered that the patient was suffering from odd symptoms such as being unable to identify common objects in his left hand without looking at them.
The brain contains two cortical hemispheres that work together to process information. In the case cited by Dr. Ricker, the two hemispheres of the patient's brain had experienced a disconnection, which resulted in neurological symptoms ranging from the inability to identify objects with the left hand to being unable to write letters of the alphabet with his left hand.
Common symptoms of interhemispheric disconnection include left visual field dyslexia, left upper limb ideomotor dyspraxia, left hand anomia, left visual field dysnomia and left ear suppression during dichotic listening tasks. The National Institutes of Health postulates that the posterior body of the corpus callosum is a particularly important connection point for visual-motor responses.Learn More
The corpus callosum sits between the two hemispheres of the human brain and acts as a conduit for nerve signals between them. According to About.com, this bridge allows motor, sensory, and cognitive information to flow between the left and right hemispheres.Full Answer >
The occipital lobes, located at the rear of the brain, processes visual information, as shown on the National Institutes of Health website. Although the occipital lobe is responsible for handling the bulk of the visual information coming to the brain, the posterior portions of the parietal and temporal lobes also participate in processing visual images, according to About.com.Full Answer >
Common symptoms of bad nerves, or significant anxiety in medical terms, are muscle tension, digestive problems, changes in sleep and anxiety attacks, according to About Health. Numbness is also a symptom of bad nerves, although it occurs more rarely; increased heart rate and sweating are the more basic and frequent symptoms of bad nerves.Full Answer >
The large fiber tract connecting the cerebral hemispheres is the corpus callosum. This huge bundle of nerve tissue lets the brain's right and left sides communicate. The corpus callosum is situated in the middle of the brain under the cerebrum, the largest section of the brain.Full Answer >
