Flow diagram of how information flows through the brain? I am a Artificial Intelligence researcher with a interest in neuroscience. 

I was wondering if flow diagrams exist of the way information flows from sensory inputs through the parts of the brain (and their function) to form output actuation signals for moving the body? 

This kind of flow diagram might be used as a kind of blue print for constructing intelligent systems.

Such diagrams of information flow of other animals besides humans (less complex systems) would also be very welcome and useful.
Most flow diagrams with the detail your require are for rudimentary sensory functions (such as seeing, eye tracking and other simple functions) can be found in any neuroanatomy textbook. The one I have experience with is "Neuroanatomy: Text and Atlas" by John H. Martin.

Alternatively, if you're looking for a more functional interpretation of how information flows through the brain in terms of behaviour, the most detailed model that I know is Spaun. A diagram of the brain model taken from the Science paper can be seen below:



Other models using the Neural Engineering Framework and the Semantic Pointer Architecture used in Spaun may also have the types of diagrams you are looking for. For example, consider this motor control diagram from Travis DeWolf's PhD thesis on Adaptive Control.
