A room filled with people at a party contains a number of conversations which represent numerous subjects and emotions. Thousands of symbols are perceived as sound waves varying in amplitude represent different symbols. An abundance of unique sounds stemming from our vocal chords represent an overall subject in a sentence by eclectically placing together individual sounds of letters, words, and sentences. A sentence such as, "Wow, your family is amazing, I love the way each person carries themselves and smiles" contains fifteen words to carry out a message of gratification. Our brains are phenomenal at decoding sounds like this previously stated sentence and it acts as a computer processing sounds at an astounding speed. It pieces together each sound of a letter that makes up a word which represents a symbol to place the symbol in the context of a sentence. For example, "Wow" is a symbol for excitement, "your family" is a symbol that makes your brain feel excitement about your family, "is amazing" augments your previous thought by adding positivity about your family, etc.
Body language has an astounding correlation with symbols. One could pose as being sad, happy, depressed, mad, etc. If we observe someone, we make a conclusion based on their body language on whether they are happy, sad, or angry. These symbols(happy, sad, angry) in our brain contain a number of responses based on our conclusive observation. It is like a program which contains "if" statements. This has much to do with language decoding because observing one's body language and decoding various sounds both contain learned response.
Physiologically, a unique set of neurons represent a sentence in where we could understand every word. This is why when we do not know what a word means, we figure out what it means in context of words we understand therefore realigning a new set of neurons that represent this newly learned word. To test this theory of a unique set of neurons representing a sentence, I used my EPOC neuroheadset. I played the first ten seconds of a song called "Say Hello to Heaven" to see how the sensors responded. I did ten trials of listening to the first ten seconds of the song to see if the headset responded and it did.
This gives into the argument that our brains act as extremely complex programs which run through our memory just as a computer runs through it's hard drive. Symbols associated with language are learned in the early years of a human being's life. The abundance of symbols and associations in language make it hard for neuroscientists to come up with a correlation between clinical observation and physiological explanation.
