We speak with language and direct communication with understandable and easy to understand with other people. like we can eat with our hands, see with our eyes, listen with our ears and so on.

We have also been able to move anything in a simple way and it is like in an organization we will definitely have a leader who teaches, controls and guides us in the organization.

Therefore we have leadership over all the actions we have taken before. whose name is the brain is a system that is centered directly with the pioneers, leaders, mentors, and guides for what we have done so far by using our language so that we can communicate with each other with others.

Language has a combination of both processes, namely productive and receptive processes. while the receptive process that runs when capturing, processing, understanding and understanding the meaning of the spoken codes. while the productive process is called encoding which often occurs and is involved in conversation, conversation and others.

Broca area

Broca's area is this part of the human brain located in the superior frontal gyrus which is in the frontal lobe of the cerebral cortex. but cannot be directly understood by the listener. Just as "Tan" was killed by Paul Broca, he had lesions or bruises around Broca's area, resulting in him being unable to speak properly.

Wernicke area

Is the direct encounter with someone who can speak well and fluently, but words and sentences are not surprising, Wernicke's area is an area in the brain and plays an important role in language development. This area is also known as the decoding area.

Broca's area functions as an encoding or production of language, while Wernicke's area functions as a language decoder or receiver. then there will be a conversation that is smooth and precise, without obstacles that seem not to be understood what other people are talking about.

However, in this language development, many studies have shown that it is not the left hemisphere of the brain that can speak directly with the right hemisphere as well, as long as it is often trained properly and correctly by using each language.
