How the Brain Processes Sign Language ?

The brain is a pretty complex thing and there are lots of neurons, receptors and senders, receivers so there are multiple functions at a single time; hence, the work is pretty much dimensional to process. Many people are deaf and if you go to count them there are about 70 million who use sign language as their preferred communication bridge. It hasn’t been identified that when we converse through sign language which part of the brain activates and functions although they access similar brain structures as spoken language. It is discovered by scientists that broca area positioned in the left hemisphere is considered as the center for spoken languages and is quite crucial for spoken languages. This is important because in this part many things need to be filtered first; this is also the place where the brain can process the grammar and meaning of the word regardless of whether it is spoken or signed language.

The ability to speak is one of the essential characters of a human and because of these characters humans are different from animals. Since humans can communicate with each other in a special type of language which is only understood by them and not by animals or any other species can understand or speak it. Many people unintentionally would equate speech and language. There is much research on sign language since the 1960s and it gives total different pictures and somewhere it has given similarities as well sometimes it gets very difficult for a human being to derive an image and a consistent picture of how both forms of language are processed in the brain.

Nowadays it is very clear that sign languages need a lot of understanding and they are independent languages that have a complex organization on multiple linguistic levels such as grammar and meaning. Older studies on the processing of sign languages in the brain of human beings had already found some interesting findings in which there are many similarities and also differences between sign languages and spoken languages. Researchers from MPI CBS wanted to recognize how the brain functions and which regions of the brain are involved in the processing of sign language across different types of studies.  Hearing and understanding people are two different things; hence, it is extremely complicated to describe it.
