The Role of Emotions in Consciousness
Dr. Ommaya focused much of his career on the study of consciousness, the brain, and mind. This interest derived from his reading of Pennfield’s work on surgical treatment of epilepsy. His work in traumatic brain injury was influenced by his interest in how consciousness is altered and how it recovers after traumatic injury. Key to his observations is the role of the limbic system and emotion as foundational for consciousness.29 In his view, emotion is the trigger to action and other aspects of rationality are tools to justify action. Dr. Ommaya saw consciousness as an emergent property of the evolution of neural structures. Consciousness is the result of evolutionary forces directed to improving the efficiency of mental function. The reintegration of thought and action after traumatic injury provided the experimental context for Dr. Ommaya's thoughts.
It is popularly assumed that emotion disrupts cognition. However, neurophysiology and Dr. Ommaya's TBI research emphasizes its fundamental inseparability. Dr. Ommaya defined four steps in the evolution of consciousness. 1) reflex and avoidance reactions; 2) sensory inputs merged with multisensory neurons in the mesencephalon; 3) interactions formed between sensory and limbic systems and memory; and 4) reinforcement of thalamic neural centers which relays information between sensory and motor centers. Dr. Ommaya discussed how the limbic system and emotion motivates action and focuses attention.

Famous quotes containing the words role and/or emotions:
“But however the forms of family life have changed and the number expanded, the role of the family has remained constant and it continues to be the major institution through which children pass en route to adulthood.”
—Bernice Weissbourd (20th century)
“The more I read and the more I talked to other parents of children with disabilities and normal children, the more I found that feelings and emotions about children are very much the same in all families. The accident of illness or disability serves only to intensify feelings and emotions, not to change them.”
—Judith Weatherly (20th century)
