Are there 2 angular gyrus one in each side of the brain?
yeah, there have to be. brain is symmetrical. and although they may serve not exactly the same function or different functions for different people, there always has to be two.
RIGHT LOBE. Because sensory and motor, both types of fibers cross to apposite side of the brain, in the area behind central sulcus, called as post central gyrus you have sensory area there. In front of the central sulcus, you have a motor area, called pro central gyrus. ( Sensory nerves carry signals to words brain and motor nerves carry sensations away from brain.)
The primary motor cortex, or M1, is one of the principal brain areas involved in motor function. M1 is located in the frontal lobe of the brain, along a bump called the precentral gyrus. While there may be some general rules about one side doing one thing, the actual situation is much more complex than we ever thought. Any kind of left brain-right brain dichotomy of this type is at best a gross simplification. While…
Why does the left side of the brain control the right side of the body and vice versa What benefit can this possibly bring to efficient brain functioning?
The right side of your brain controls the left side of your body and vice verse. If the person experiences injury on the right side of the brain, then the left side of the body will be affected. If the person experiences injury on the left side of the brain, then the right side of the brain will be affected
The brain is made up of nerve cells (neurons), among other things. Activity, by which I assume you mean motor activity, is regulated by neuronal systems in the precentral gyrus, which is also referred to as the motor cortex. Damage to the motor cortex will cause paralysis on the opposite side of the body (i.e., damage to the right motor cortex causes paralysis on the left side of the body, and vice versa).
