Universal mono-command support system for users with severe tetraplegia and anarthria
No full textThe paper describes two input devices and a software interface that allow severely impaired people to easily interact with a personal computer. The first input device does not require residual movement but makes use of skin electrical signals and applies Artificial Neural Networks to decode the mind-driven commands. The second input device is an evolution of a proximity sensor that can be activated using minimal residual movements, therefore it is suitable for the main part of motor disabilities. The software interface can be adapted to any kind of input device and makes it possible to access any standard software installed on a PC
Autoipnosi: strumento per il mantenumento dell'omeostasi per la prevenzione della malattia attraverso l'attivazione delle risorse interiori
No full textStarting from the studies on consciousness, from the point of view of both neural correlates and awareness and self-awareness, the experimentation aims to verify the possibility of being able to intervene, through the use of hypno-sis, on the evolutionary process of homeostatic regulation and adaptation, considered as an expression of pathologies in the clinical field, but also as a lever of evolution in the educational and social field. In consideration of vari-ous clinical studies on hypnosis that report positive results after hypnotic treatment, the hypothesis is based on the possibility of acting, for preventive purposes, on the somatic, psychological and relational disfunction, which can induce an energetic blockage of emotionality, educating the subject to recover and manage their energy and balance. The subjects examined and taken into consideration for research purposes were administered the MHQ test, a self-assessment scale for psychoneurotic patients, whose score, while still showing normal values, highlights the tendency to approach pathological values, at risk for the subject. The hypothesis verified is as follows: the use of hypnosis (het-erohypnosis-positive conditioning) for a period of one month, with weekly sessions and subsequent use of self-hypnosis, every day, for two months for preventive purposes, can allow to deconstruction the deviances and restore the resources blocked in the body structure, bringing the subject back to con-sciousness, directing the learning towards the recovery and maintenance of psychic balance.
At the end of the trial, the verification of the achieved results was corrobo-rated by the re-administration of the MHQ test and the statistical evaluation of the outcomes, which proved to be significant.
The positive outcome of the study suggests that therapists can apply the ex-perimental method on a systematic basis, making possible a fast and definitive recognition of self-hypnosis - as well as hypnosis - as a scientific discipline
A proposal to measure the Rabi oscillations in the retinal rod cells
No full textStarting from the assumption that rod cells are sensitive to single photons, we propose a method to verify the existence of a quantum superposition in the retina, observing the Rabi oscillations in the quantum interaction of a coherent laser light with the rod cells. The computer simulation shows that the oscillations visibility is a robust parameter, so that it would be possible to observe the fringes also in presence of strong decoherence. The feasibility of the experiment is ensured by the new MEA (microelectrode array) technology, that allows to record the transretinal voltage change of a single retinal segment
The search for biological quantum computer elements
Full text linkThe difficulties encountered in explaining the capacities of the human brain to generate conscious experiences with a neuron switching model has lead researchers to speculate that quantum phenomena may be involved in the human thinking process. This speculation goes beyond acknowledgement of the quantum mechanical basis for bio-molecular chemistry but suggests the architecture of brain functioning parallels the architecture of quantum computers. In this model classically observed neural components act like transmitting and receiving channels to quantum elements analogous to the state-preparation and measurement components in quantum computer architectures. Theories proposed by Penrose and Hameroff suggest such quantum element fields may be supplied by the microtubule structure encountered in neurons, while the DNA field has also been proposed as a candidate for quantum computation. Objections to the quantum brain model rests primarily on the de-coherence expected in the warm-soup environment which simply compounds the isolation difficulties encountered in conventional approaches to quantum computer element construction
Artificial Neural Networks, Dynamical Systems and Self-Organization
No full textThe world around us and the living beings are complex dynamical systems, with a high capability of self-organization: the book explains the principles that rule this exceptional characteristic. As well as living beings, Artificial Neural Networks, that constitute one of the most promising tools for the development of Artificial Intelligence, are self-organizing dynamical systems: this makes them an optimal tool to analyze and simulate the brain and any expression of organized complexity
Artificial Neural Networks Identify the Dynamic Organization of Microtubules and Tubulin Subjected to Electromagnetic Field
No full textMicrotubules (MTs) are cylindrical polymers of the protein tubulin, are constituents of all eukaryotic cells cytoskeleton and are involved in key cellular functions. MTs are claimed to be involved as sub-cellular information or quantum information communication systems [1][2][3]. MTs are the closest biological equivalent to the well-known carbon nanotubes (NTs) material. We evaluated some biophysical properties of MTs by means of specific physical measures of resonance and birefringence in presence of electromagnetic field, on the assumption that when tubulin and MTs show different biophysical behaviours, this should be due to the special structural properties of MTs.
The experimental results highlighted a peculiar physical behaviour of MTs in comparison with tubulin. This paper presents the dynamic simulation of MT and tubulin when subjected to electromagnetic field. Their level of self-organization was evaluated using artificial neural networks
Battery of Experiments and Signal Processing to Test the Existence of Quantum Properties at a Neural Level
No full textThe academic interest on the quantum mind framework was growing in the last decades, but experimental evidences are still lacking. This essay intends to represent a contribution and a trial in this direction. Building an experimental basis for the quantum mind framework means being on the right way to create a truly scientific - as falsifiable - body of theories. The book includes contributions of Rita Pizzi (University of Milan, Italy) and Wolfgang Baer (Nascent Systems,Inc, former Naval Postgraduate School, Monterey)
