Download EMERGENCE OF INTRINSIC REPRESENTATIONS OF IMAGES BY FEEDFORWARD AND FEEDBACK PROCESSES AND BIOLUMINESCENT PHOTONS IN EARLY RETINOTOPIC AREAS: Toward a biophysical homunculus represented by an iterative model
In this paper, we have proposed a theoretical model involving a biophysical picturerepresentation without homunculus during visual imagery. We do not claim to have explained the enigma of consciousness, but our goal was to show that the somewhat mysterious homunculus phenomenon may be elucidated with the help of retinotopic representation, rapid feedforward and feedback connections (between V1 and V2), and nonlinear iterative processes during visual imagery. We also proposed that emergence of an iterative biophysical picture-representation in retinotopic V1/V2 and the semantic interpretation of an emerged biophysical picture are two different things, although they may be tightly connected. The first is a biophysical picture-representation generating process (picture-like) while the second is a language-like semantic interpretation process. However, they can induce each other’s representations. The human memory can operate through intrinsic dynamic pictures and we link these picture-representations to each other during language learning processes. During language learning processes, the development of picture-like and languagelike systems becomes a quasi-independent neural process. An important implication of this hypothesis is that long-term information storage of the language-like and picture-like representations can be encoded by nonlinear epigenetic redox processes. The evolutionary advantage of the biophysical picture representation is that it makes possible, for example, for us to imagine events, compose and design objects, etc. However, if it can be proved that perception of cortical-induced phosphene light is due to biophotons; intrinsic regulated biophotons in the brain may serve as a natural biophysical (redox molecular) substrate of visual perception and imagery. In other words, intrinsic biophysical visual virtual reality may emerge from feedback and feedforward iterative operation processes and biophotons in early retinotopic V1 and V2 areas. Kosslyn’s reality simulation principle states that mental imagery mimics the corresponding events in the world. However, our concept of intrinsic biophysical visual virtual reality (by iterative processes) in retinotopic areas may be nothing else than a possible biophysical basis of the reality simulation principle in the case of visual imagery.
