There is no such evidence. There is quite concrete evidence that this is a myth.

“Of course, some brain functions occur in one or another half of it - for example, the left side is responsible for speech, and attention is born in the right. But that radical division, about which it is customary to speak, does not exist. So the right hemisphere is also involved in such aspects of speech as intonation and accent.

Experts believe that the myth of the separation of hemispheres originated in the 1800s, when scientists discovered the loss of certain brain functions when one of the hemispheres was damaged. False beliefs were reinforced in the 1960s with the split-brain work of Robert Sperry and Michael Gazziniga, which eventually won the Nobel Prize. Scientists have conducted studies of patients who, as a last resort in the treatment of epilepsy, underwent removal of the corpus callosum - a group of neuronal fibers that connect the hemispheres. They found that when the hemispheres were not connected, they responded differently to stimuli and, accordingly, were responsible for different functions.

But neurology has never agreed with the concept of right or left hemisphere dominance. In fact, if one of them worked much more actively than the other, it would be extremely ineffective for the functioning of the entire brain as a whole. ”

No, this belief is not a myth, it is a confirmed fact. The right hemisphere is really responsible for creativity, creativity, imagination. The left hemisphere is responsible for analysis, synthesis, logic, writing, speech processing, etc. This theory was put forward by Roger Sperry, who proved it experimentally.
