I know that the emotion chip allowed Data to experience emotions, but is there a canon explanation of the other information it contained? I recall a reference somewhere to information from Dr Soong? For example, Data is able to laugh when it is installed (ST: Generations), and not the way he laughs during TNG (which is very annoying come to think of it!).
Did the extra information consist solely of a series of routines required to accurately display the physical side of emotions as well e.g. how to laugh properly or was it more than that?
