It means that one side of the brain is dominant. Thank you again for all of your groundbreaking research on the cerebellum, Jeremy Schmahmann. The reverse is true for right-handed people—the left hemisphere is stronger when it comes to such movements. Another condition closely tied to language impairments is dysphagia, which involves difficulty swallowing. Some areas of the brain are more active than others during particular tasks, and one hemisphere may be more involved than the other in specific parts of a larger mental operation. The content of this field is kept private and will not be shown publicly. Blood supply to…, The occipital bone is the trapezoidal-shaped bone found at the lower-back area of the cranium.
The “left-brained” type has been described as logical, analytical, and detail-oriented, while “right-brained” people have been characterized as creative and intuitive—though other supposed traits have been attributed to each. However, the hemisphere of the brain that is affected by the injury can determine what specific symptoms and problems the body could have.
“I had a stroke five years ago causing paralysis on my left side which remains today.
To read more about the cerebellum, check out my previous Psychology Today blog posts. Because the language center of the brain resides in the left hemisphere, left side stroke patients often struggle with language impairments after stroke like aphasia. After a left hemisphere stroke, you can optimize recovery by understanding the unique side effects that may occur. The brain, being an intricate organ, performs a lot of functions. Difficulty in processing the information on the left visual field. There are more side effects that can occur after stroke, but the impairments listed above are the most common for left hemisphere stroke patients.
It’s worth noting, though, that strokes on the left side of the brain are more likely to result in impairments of verbal working memory. Sebastian Ocklenburg, Ph.D. on June 7, 2020 in The Asymmetric Brain.
(In any case, the "left-brained" and "right-brained" types are not scientifically supported.). But are we? This research was led by Maria Assunta Rocca, M.D., Ph.D., of the Division of Neuroscience at Vita-Salute San Raffaele University in Milan, Italy.

Studies suggest stammering is linked to a defect in the left hemisphere of the brain. Convert sounds to language and translates meaning. New neuroscience reveals the dying brain's first and last experiences as we pass away. You most likely excel in academics, especially math and science.
This was another light-bulb moment for me. Check out all our devices by clicking the button below: Our customers say it best! Both sides of the brain collaborate to handle major functions such as language processing and vision. Here's a quick background sketch of the cerebellum and some terminology: Cerebellar is the sister word to cerebral and means “relating to or located in the cerebellum.” There are two cerebral hemispheres located in the cerebrum (left brain-right brain) and there are two cerebellar hemispheres located in the cerebellum. While the brain’s left and right hemispheres do handle distinct functions, their duties aren’t strictly divided according to broad categories like “logical” or “creative.” People can't be split neatly into groups with special strengths based on one hemisphere being more dominant. The list below provides a summary of possible symptoms. It affects the person’s ability to pay attention to details. It is, in fact, a pair of two colliculi…, The posterior pericallosal branch of the posterior cerebral artery is one of the arteries serving the brain. Although his skills as a neurosurgeon were undeniable, he alienated most of his allies at peer-reviewed neuroscientific journals and didn't have an outlet for getting his ideas published.

The left side of the brain controls the right side of the body. However, if a stroke on the left side of the brain results in vision problems, those impairments will manifest in the right visual field. My father, Richard Bergland, was a world-renowned neurosurgeon, neuroscientist, and author of The Fabric of Mind. Evidence suggests that children can process language in both brain hemispheres but that language processing becomes more "left-brained" as we age.
Through his research at Mass General Hospital, Schmahmann has developed a theory called “Dysmetria of Thought” which is basically the hypothesis that the cerebellum fine-tunes cognitive thinking the same way it fine-tunes muscle movements. Because I’m an athlete and not a scientist, I would repeatedly say that the revolutionary ideas I presented about the cerebellum a decade ago were an ‘educated guess' and 'hunches' based on conversations with my father.
