The left hand operation is controlled by the right brain, and the right hand operation is controlled by the left brain. If both hands are operated at the same time, the left and right brains need to be coordinated at the same time. People with poor coordination skills will be out of sync or occupied by their usual hands.
People usually think with only one right brain, but not everyone thinks with the right brain. Some people also develop left-brain thinking, so they are not sure why they can't draw a circle with one hand.

Left and right brain training methods:
The left hemisphere is mainly responsible for logical understanding, memory, time, language, judgment, arrangement, classification, logic, analysis, writing, reasoning, inhibition, five senses (vision, hearing, smell, touch and taste), etc. Its way of thinking is continuous, continuous and analytical. So the left brain can be called conscious brain, academic brain and language brain.
The right hemisphere is mainly responsible for spatial image memory, intuition, emotion, body coordination, visual perception, art, music rhythm, imagination, inspiration, epiphany and so on. Its way of thinking is disorderly, jumping and intuitive. Sperry believes that the right brain has visual functions, such as planning, creativity and imagination.
It has the functions of cosmic vibration and sound, such as sixth sense, perspective, intuition, inspiration, dreams and so on. ; Ultra-high-speed automatic calculus functions, such as mental arithmetic and mathematics; Ultra-high-speed mass storage, such as speed reading and memory. The right brain, like a universal doctor, is good at finding various solutions to problems, and many advanced thinking functions depend on the right brain.
