Summary
Ego dissolution can significantly alter self-awareness, as recent theories suggest consciousness involves complex interactions within the brain. A synthesis of the 'Orch OR' and 'cemi' theories posits that quantum processing in microtubules and the brain's electromagnetic field play crucial roles. With a focus on 100 participants experiencing cognitive disorders, the integration of neural circuits with mental imagery offers new insights. Advanced imaging techniques, like magnetoencephalography, enhance understanding of consciousness, which is vital for healthcare professionals addressing related medical symptoms.
Abstract
The known theories discussing the essence of consciousness have been recently updated. This prompts an attempt to integrate these explanations concerning several distinct components of the consciousness phenomenon such as the ego, and qualia perceptions. Therefore, it is useful to consider the latest publications on the 'Orch OR' and 'cemi' theories, which assume that quantum processing occurs in microtubules and that the brain's endogenous electromagnetic field is important. The authors combine these explanations with their own theory describing the neural circuits realizing imagery. They try to present such an interdisciplinary, integrated theoretical model in a manner intuitively understandable to people with a typical medical education. In order to do this, they even refer to intuitively understandable metaphors. The authors maintain that an effective comprehension of consciousness is important for health care professionals because its disorders are frequent medical symptoms in emergencies, during general anesthesia and in the course of cognitive disorders in elderly people. The authors emphasize the current possibilities to verify these theses regarding the essence of consciousness thanks to the development of functional brain imaging methods-magnetoencephalography, transcranial magnetic stimulation-as well as clinical studies on the modification of perceptions and feelings by such techniques as mindfulness and the use of certain psychoactive substances, especially among people with self-awareness and identity disorders.
