In the19th century, a pair of neuroscientists - Dr. Things get more complicated for vision: Nerves from the left sides of both eyes connect to the left side of the brain, and nerves from the right sides of both eyes connect to the right side of the brain.
Generally speaking, the left side of your brain controls the right side of your body, and the right side of your brain controls the left side of your body, according to the website The Brain from Top to Bottom, which was written and developed by Bruno Dubuc, a neuroscientist at McGill University in Montreal. So, what's the difference between the two hemispheres? Surgeons pulled off the surgery, known as a hemispherectomy, "hundreds of times" in the last century, according to Scientific American. Need proof? If you remove a hemisphere from the brain of a 3-month-old baby - a surgery that doctors sometimes perform in cases of severe epilepsy and other disorders, according to the Cleveland Clinic - that baby can still grow up with normal memories and a normal personality. That's some dense text, but the point is simple: Just about everything about your brain that makes you human exists on both sides of the organ. the capacity to maintain appropriate thresholds and tolerance for frustration and failure, and to recover promptly from their effects the capacity to maintain effective and well-modulated defense reactions (i.e., repression, denying, pretending, rationalization, blaming, withdrawal, fantasy, depersonalization, obsessive-compulsive behavior and bodily reaction patterns involving alimentation, respiration, metabolism, etc.)." Harold Wolff - one of the great brain scientists of the 20th century - as saying that both sides of the brain have "the capacity to express appropriate feelings, appetites and drives the capacity … learning, memory, logic, etc.
The left side of the brain has a preference for the control of fast processes while the right side tends to control the slower processes in parallel.The book " Disorders of the Nervous System: A Primer" (Imperial Company Printers, 1995) by Dartmouth neurologists Dr. Taken together, the two studies create a convincing picture of how complex behaviour - hand motor functions and speech - are controlled by both cerebral hemispheres. Conversely, tapping with the left hand corresponded better with the slower rhythm and resulted in the right hemisphere exhibiting increased activity. As it turned out, the right hand was more precise during the quick tapping sequence and the left hemisphere, which controls the right side of the body, exhibited increased activity. In one version they were supposed to tap with each beat, and in another only with every fourth beat. In the experiment, scientists had right-handed test persons tap with both hands to the rhythm of a metronome. For example, when cutting bread, the right hand is used to slice with the knife while the left hand holds the bread. Kell and his team wanted to learn why the right hand was preferentially used for the control of fast actions and the left hand preferred for slow actions. A previous study on hand motor function that was published in the scientific publication "elife" demonstrates that this is in fact the case. The right hemisphere could be better at controlling the slower processes required for analysing the sound spectrum.
When you say 'mother', for example, the left hemisphere primarily controls the dynamic transitions between "th" and the vowels, while the right hemisphere primarily controls the sounds themselves." His team, together with the phonetician Dr Susanne Fuchs, was able to demonstrate this division of labour in temporal and spectral control of speech for the first time in studies in which speakers were required to talk while their brain activities were recorded using functional magnetic resonance imaging.Ī possible explanation for this division of labour between the two sides of the brain is that the left hemisphere generally analyses fast processes such as the transition between speech sounds better than the right hemisphere. The division of labour actually follows different principles, as Dr Christian Kell from the Department of Neurology at Goethe University explains: "While the left side of the brain controls temporal aspects such as the transition between speech sounds, the right hemisphere is responsible for the control of the sound spectrum. According to accepted doctrine, this means that when we learn to speak English and for example practice the sound equivalent to "th," the left side of the brain controls the motor function of the articulators like the tongue, while the right side analyses whether the produced sound actually sounds as we intended. Until now, it has been assumed that the spoken word arises in left side of the brain and is analysed by the right side.
