Important Aspects of the Brain Functions

Functions of the left and right cerebral hemispheres

Although the cerebral hemispheres have a symmetrical structure with two lobes that emerge from the brainstem and sensory and motor areas in both, certain intellectual functions are performed by a single hemisphere. The dominant hemisphere is usually a person occupying the language and logical operations, while the other hemisphere controls emotions and artistic and spatial skills. In almost all right-and left-handed people in many, the dominant hemisphere is the left.

Physiologists and neurologists have mapped areas of the cerebral cortex to locate and define the regions responsible for motor movements, sensory processes, memory and other cognitive functions.

The crust is subdivided into different functional areas that are actually interconnected. For example, the somatomotor area, located just outside the central fissure, is responsible for all voluntary movements of the muscles of the body. The nerve cells that control movement of the toes are at the top of the fissure, while the facial movements are controlled from the bottom delgirus angularis.



Many motor and sensory functions have been associated with specific areas of the cerebral cortex, some of which are shown here. In general, these areas appear in both cerebral hemispheres and are serving on the opposite side of the body. The association areas are not well defined and are located mainly in the front of the crust. They are involved in thinking and emotional functions and relate the stimuli received from the different senses. The language areas are an exception: both Wernicke's area, which is related to the comprehension of spoken language, such as Broca's area, which governs the production of speech, have been precisely localized in the cortex.
