Figure 3: A Kanizsa triangle Other examples of the conscious brain harmonizing the activity of various modules of the brain come from split-brain patients. In the words of Gazzaniga [8]: 
In a complication of stroke called anosognosia with hemiplegia, patients cannot recognize that their left arm is theirs because the stroke damaged the right parietal cortex, which manages our body's integrity, position, and movement. .. When patients with this disorder are asked about their arm and why they can't move it, they will say "It's not mine" or "I just don't feel like moving it"—reasonable conclusions, given the input that the left-hemisphere interpreter is receiving. The left-hemisphere interpreter is not only a master of belief creation, but it will stick to its belief system no matter what. Patients with "reduplicative paramnesia," because of damage to the brain, believe that there are copies of people or places. In short, they will remember another time and mix it with the present. As a result, they will create seemingly ridiculous, but masterful, stories to uphold what they know to be true due to the erroneous messages their damaged brain is sending their intact interpreter. 

These findings do not fit into any simple model of computation, reminding us that there remains a big gulf between the reality of biological computing and our current explanations. 

Other perspectives from which to look at information processing by the brain are those of learning and structure. Learning of memories is related to two distinct types: short-term and longterm. It is also believed that much of learning is based on recursive primitives. Recursion may be seen as the nesting of stories inside stories, dolls inside dolls, or the flowering of leaves and branches in a self-similar manner in a tree. The motor-sensory cortex maps the world as experienced by the senses and it is connected in a nested form to deeper layers. Recursive representations are used implicitly or explicitly in scientific thought, literature, art and music. It is the basis of mental images not only of physical systems but also of behavior. In music, recursion helps in the creation of structure, as in the employing of a delayed version of a tune as its own accompaniment. In Indian music, rhythms and melodies are created out of set notes constituting the *raga*, which is then syncopated, translated, and rhythmically shrunk and enlarged to communicate emotion. Baroque composers have used recursion in their canons and fugues.
