Nowadays, amphetamines constitute the prescription drugs most commonly abused by adolescents and young adults (Berman, O’Neill, Fears et al. 2008). The prevalence of problematic (mainly illegal) use of amphetamines as a stimulant by college students, and here especially before serious examinations, has also been rising. This fact represents a serious public health concern. The patient, aged 19, was awakened from from a long-term coma that had lasted 21 days following an amphetamine overdose and manifested tetraparesis, cortical blindness and deficits in cognitive and emotional processes. After a year of rehabilitation the majority of symptoms had disappeared, but cortical blindness andworking memory deficits remained. In addition, frontal lobe syndrome symptoms appeared. After two years of therapy as a result of immense tiredness caused by all an night wedding reception she started to manifest Charles-Bonnet syndrome. She experienced strange visual sensations such as visual hallucinations and saw various non-existing shapes (coloured blots, patterns and fireworks of vivid colours). She also saw objects (often terrifying) as well as animals (mainly African) and people with deformed faces and long teeth, and persons in African dress with feathers and coral beads in their hair. Her real identity was not remembered by the patient for longer than 2 hours and even then she insisted on being referred to as Shakira. She was given a qEEG examination (in open and closed eyes conditions) and ERPs with the use of auditory stimuli at the period when the hallucinations (to a small degree) still occurred. Studies conducted into the functional neuroimaging of the brain work in milliseconds in the examined patient can explain her symptoms. A comparison of the subject’s ERPs with the grand average of ERPs in healthy controls shows that the N170 and N 250 components are impaired in the subject: the occipital-temporal area of the subject brain shows a strong positivity instead of negativities. This positivity might reflect an enhanced reactivity of neurons in the corresponding area induced by the removal of lateral inhibition from the neurons as a result of local damage. ------------------------------------------------------------------------------------------------------------------------------------

Perceptual microgenesis – what are its real-time characteristics?

According to the microgenetic stance, each following instant of perception gradually grows out from the each preceding one and is essentially a continual part of it. It is difficult to exclusively differentiate past, present and future in perception, because in the currently experienced mental reality past, present and future overlap, with no very clear borders in between. However, in the practical domain these theoretical underpinnings remain useless unless we support them by specific experimental data about the more or less precise values of measurements characterizing the real-time constraints and ranges within which the microgenetic perception unfolds. Here, the general theoretical picture of perceptual microgenesis will be supplemented with some simple data on the quantitative aspects of actual microgenesis. I will review some experimental measurements of perceptual microgenesis such as the real-time values of microgenesis, typical orders with which different characteristics of the same object/event unfold, arbitrariness with which the objective order is transformed to a subjective order, the phenomenon of proactive facilitation. Microgenetic stance will be discussed also in light of the issue of neural correlates of consciousness.

In this paper I am going to argue on the existence of somatic consciousness, which has a special importance in resolving the mind-body problem. The discussion will include such issues as the range of somatic consciousness and the possibility of improving such an idea not only by interdisciplinary scientific studies but also through contemporary analytic philosophy of mind.

QUANTUM MICROGENESIS: EVOLUTION, SYNCHRONICITY, AND TENSELESSNESS

Quantum nonlocality is described in the context of a subjective duration that has a period of unconscious simultaneity of potentials that are reduced to an actual observably-identical mixed state of consciousness that deposits time and duration at the end of the mental state. Quantum microgenesis involves the observer as the agent of experience, which is a single continuum from depth to surface in the genesis of the mental state, repeating prior states of the individual. Microgenesis is generalized as prior becomings going back to the inception of the Universe. Synchronicity is the fundamental principle of Mind, Self, and consciousness. Mind is always One, which cannot be multiplied. Synchronicity is beyond any process of inanimate quantum nonlocality. It is outside of the physics, as Mind is based on the actualization of the mixed state of the human mind rather than the single quantum eigenstate given by the physics. Consciousness is thus a process of an irreducible and indivisible Mind in ourselves and the acausal realm of synchronicity. The mental-physical process evolves from the unconscious subjective time in the period of simultaneity, proceeding to the actuality of the mixed state of consciousness through synchronicity in its operative role as manifestation of Mind. Periods of unconscious duration and simultaneity exist as potential and only become actual at the synchronous moment of conscious observation at the end of the cyclical mental state.

PROCESSES OF CONSCIOUSNESS AND DREAMING IN THE MIND

The Mind is described in terms of our individual and collective experiences. The role of observation by Mind is supported by empirical data that quantum states can be created and changed by the process of repeated observation, and is described by a classical equation, which defines the genesis of information from reduction of uncertainty. This uncertainty is then generalized to the uncertainty of quantum processes. The state of consciousness is always “now,” with a unitary movement forward of Mind in time. This movement involves irreversible processes, which produce mixture of states, such that choices of states are enabled to occur. Such processes appear nowhere in physics, but rather reflect the role of the observer. Within the duration of the mental state, experience arises by repeated observation of the mind/brain state. The processes of conscious experience involve movement from the uncertain unconscious to the certain consciousness, the outgoing process, and vice-versa in dreaming, the inward-going process. Psychopathology is the result of an imbalance and/or dysfunction of one or both processes. In dreaming, in the absence of consciousness, subjective time moves equitably forward and backward in time. This kind of temporal movement is discussed in relation to the Dreamtime of the Australian Aborigines.
