The left hemisphere is largely responsible for verbal functions such as speaking, reading and writing, and analytical skills such as problem-solving, logic and interpreting information. Each hemisphere is divided into four parts, or lobes, the frontal, parietal, occipital and temporal. All have specific functions - learn them well. The four lobes do not work in isolation and have significant associative areas that receive, send or integrate information between other parts of the brain and lower body. Associative areas are larger in humans than in any other species, occupying 75per cent of the cerebral cortex.
Many students appear to become confused.
Firstly, both must reside in the left hemisphere that specialises in verbal function. Just remember that since Broca's area is involved in the physical production of speech, it is adjacent to the motor cortex in the left frontal lobe, which controls all voluntary movement. Think Broca, think speaking. Wernicke's area is responsible for understanding speech and thus must be in the lobe responsible for hearing - the left temporal lobe. Think Wernicke, think listening.
