Biogenetic structural theory takes an entrainment view of the nature of consciousness. Human consciousness is a function of the brain and is mediated by networks of living neural cells that develop from initial, neurognostic models of self and world. Models interact or "entrain" as a constantly changing field of experience. The entire population of neural models that may potentially entrain within the field of consciousness is called the "cognized environment.” The organization of the network of cells (the "conscious network") mediating (...) consciousness operates according to a circadian cycle. Recurrent phases of consciousness are cognized and labelled. Transformations between phases of consciousness are often ritually controlled by society in order to control experiences that are in turn interpreted in terms of the society's cosmology. Recent developments in the biogenetic structural study of consciousness are summarized, including studies of transpersonal experiences, the development of consciousness in early life, and the advantages of neurophenomenology.

The purposes of this paper are twofold: first, I wish to correct a systematic bias in Husserlian transcendental phenomenology. This bias is in favor of intuition of essences of meaning and against the intuition of essences of sensation. This bias is explained as a product of Husserl's mind-body dualism. Second, I suggest the possibility of a neurophenomenology from a biogenetic structural point of view. This neurophenomenology merges the knowledge of essences derived from mature contemplation with knowledge of the structures of (...) experience derived from neuroanthropology. After addressing these two issues I proceed to describe the sensorium from a neurophenomenological perspective, and the constituent element of perception, the dot. I hypothesize fat experience arises in the dialogue between prefrontal cortical processes and sensorial processes, that experience is constituted within a field of sensorial dots that arise and dissolve in temporal frames. I conclude that Husserl's view of the phenomenology of time is essentially correct and is both in keeping with findings from current neurophysiology, and amenable to a modem scientific view of consciousness and to many of the religious traditions encountered by ethnographers. The implications of a neurophenomenology for the anthropological study of consciousness are suggested. (shrink)

A biogenetic structural explanation is offered for the cross‐culturally common mystical experience called portalling, the experience of moving from one reality to another via a tunnel, door, aperture, hole, or the like. The experience may be evoked in shamanistic and meditative practice by concentration upon a portalling device (mirror, mandala, labyrinth, skrying bowl, pool of water, etc.). Realization of the portalling experience is shown to be fundamental to the phenomenology underlying multiple reality cosmologies in traditional cultures and is explained in (...) terms of radical re‐entrainment of the neurological systems mediating experience in the brain. Phenomenological experiments with mirror portalling devices from both the Tibetan and the Tsimshian religious traditions are reported. (shrink)

The author presents a biogenetic structural theory of the body image in human beings. The theory accounts for both the universal principles and the variance in body image cross‐culturally. All humans develop a neurocognitive model of their body which combines information about the body obtained via both the internal and external sensory systems. Their experience of themselves is mediated in part by this model. The initial model of the body is "hard‐wired" and already present and active in the cognitively and (...) perceptually competent pre‐ and perinatal human being, and develops as a consequence of both genetically imposed and socioculturally influenced processes of growth. The role of behavior in this process is shown to be the control of perception such that the body image experienced in perception approximates that anticipated by the cognized self. The theory accounts for the use of the body‐assymbol and the distortion of the body image for communicative purposes. The neurophysiology of imagery is reviewed and suggestions are made for possible clinical methods that might be used to effect therapeutic changes in pathological body imagery. (shrink)
