Document Summary

What is language: systematic and conventional use of sounds (or signs or written symbols) for the purpose of communication or self expression. Must have symbols to represent something - reference: reference (arbitrary, syntax: rules to govern, intentionality, communication systems in other animals. So despite these communication systems being complex, they all lack a part of what we classify as human language. Wernicke-geschwind model: a network of serially connected brain regions that process language - this is how we use and percieve language, localization of perception, comprehension, production. What you want to say and sends it down to the muscle. Angular - transforming written into auditory signals: each region performs a specific function, thus damage to specific regions should have predictable effects. Then sends it along the arcuate fasciulus to broca"s area. Then transfers this to motor cortex so you can say what you want to say. Sent to angular gyrus - translates visual signals to auditory signal.
