Thought 

Human Thought
The physiological process of mentation.  
 NOTE: We are including the complexType Thought without any stipulation for how a set of thought elements or types could or should or will be constructed. There are any number of ways this concept might be used, but an accepted definition, which involves the much-disputed concept of what constitutes self-consciousness or awareness in terms other than physiological, is not within our present scope to support or defend.  
An example of Thought which could be described as a process from the viewpoint of an observer, though perhaps not characterized as coherent awareness or communication would be the brain activity of an autistic person or someone in a coma or even someone asleep.
