While this perception may seem useful, it actually creates an erroneous portrait of the human mind. ALL the parts of the human brain-mind are simultaneously present and thus their interactions are synergic. Animals that have only a brainstem cannot be compared with humans which have a brain stem AND a limbic system AND a cortex. The limbic system is a complex of eight different parts. When taken together, its functions seem to govern emotions, feelings and tacit forms of knowing.
Many studies indicate that the right cerebral cortex is also related to the affective domain.
Some researchers report a larger physical connection between the limbic system and the right cortex than is found in the connections to the left cortex. It is likely that the limbic system apprehends the context or pattern of experience and depends upon the right cortex to prepare neural information for the left brain to put into conventional languages for reading, writing, ciphering and reasoning. Much of what educators have traditionally called the affective domain originates in the central nervous system, the brainstem, the limbic system and the right cortex. It is through these components of the brain-mind system that experience and information is prepared for human action. Until recently, this preparation function was largely ignored because it is fundamentally without standard language and vocabulary to describe it.
