As we mentioned earlier,, that HEMISPHERES / CORTEX is our BRAIN is divided in four major parts called lobes i..e.. FRONTAL (divided in two sub parts / lobes,, SUPERIOR FRONTAL & INFERIOR FRONTAL),, PARIETAL,, TEMPORAL & OCCIPITAL LOBE.. There are cortical areas in each part / lobe associated with particular / pre-defined or pre-assigned functions..

The Right & Left HEMISPHERES / CORTEX are almost same in shape.. Most of the cortical areas in both HEMISPHERES are also same..

Our BRAIN is the centre of our nervous system.. It is the most complex & amazing organ / part of our body.. In the modern age of technology,, it is a challenge or we can say a mystery to scientists to know the mechanism or system by which the BRAIN activity gives rise to thought & consciousness.. The mechanism / system of some areas are now revealed but lot of things or we can say major parts / areas of functioning of our BRAIN are yet to be revealed..

Our BRAIN contains approximately 100 billion neurons;; communicate internally with the help of fibres that carries electromagnetic signals to specific & different parts of BRAIN & BODY..

Our BRAIN acts as a commander of our body,, controls other parts / organs.. The most promising / understood to general approach is to treat our BRAIN as biological computer.. While different from PC but very similar to take / gather information (input),, store,, process in central nervous system (CPU) & give most suitable / logical result(s) (output)..
