Each convergence zone handles a category of objects (faces, animals, trees, etc): a convergence zone does not store permanent memories of words and concepts but helps reconstructing them. Once the image has been identified, an acoustical pattern corresponding to the image is constructed by another area of the brain. Finally an articulatory pattern is constructed so that the word that the image represents can be spoken. There are about twenty known categories that the brain uses to organize knowledge: fruits/vegetables, plants, animals, body parts, colours, numbers, letters, nouns, verbs, proper names, faces, facial expressions, emotions, sounds." (Damasio, 1999).
Damasio is the firm believer of the theory that the reasoning area of the brain and the area of the brain responsible for generating emotions virtually overlap each other. As a result and thus he derives the hypothesis that emotion and reason cooperate. He believes that this is the neural, or better to state physical evidence in favour of his theory. Damasio also implies that this is the proof of the brain-body communication that is so much essential for the survival of a species.
In his current neurobiological work 'The Feeling of What Happens: Body, Emotion and the Making of Consciousness' Damasio states that evolution developed two different levels of co ...
