Human sub-consciousness information has been the interesting aspect of research and investigation because many convincing challenges remain. We believe that there must be connected information between brain signals and sub-consciousness states, which may be involved and represented during the transition states and useful for A Brain– Computer Interface (BCI) [1]. BCI is often called a mind-machine interface, or sometimes called a direct neural interface or a brain– machine interface, which is a direct communication pathway between the brain and an external device. BCIs are often directed at assisting, augmenting, or repairing human cognitive or sensory-motor functions. Moreover, the use of BCIs can also be useful for humanoid robot applications . Till date, humanoid robot has been recognized as the best robotic type in robotic technology, which can be functioned closely to human activities. Such a robotic type requires many components and related technologies for realistic applications, where the main part of such robotic type components is the brain communication and commands. To obtain the realistic robotic brain and its functions, the brains signal and communications are required to manipulate, pattern and test, therefore, the searching of realized technique for brain signal monitoring and encoding remains. Basically, terahertz (THz) pulse generated by laser is the only one that can be used to probe and connect to the brain signals without damage . The brain signals can be modulated and demodulated by light via the THz carrier, where in this case the THz Rabi frequency is formed by wave-particle duality of light within the microring resonator , in which the light probe can be generated by the particle (photon) under the Cerenkov radiation . Cerenkov radiation has become the interesting phenomenon which can be occurred in many aspects of natural behaviors, where in this study, a model of space-time paradox concept is proposed to describe the consciousness|sub-consciousness paradox, where the connection between light probe and brain signal can be formed and the mind and mater interfacing information described, which is useful for possible mind and dream investigations. The uncertainty of the paradox pair is also involved and discussed. To form the coupling output of synapse and THz light signals. The Rabi frequency is the frequency of oscillation for a given atomic transition in a given light field It is associated with the strength of the coupling between light and the transition. Rabi flopping between the levels of a 2-level system illuminated with resonant light, which will be occurred at the Rabi frequency. The Rabi frequency is a semi-classical concept as it is based on a quantum atomic transition and a classical light field. In this study the synapse signal within the human brain is modeled as an electrical pulse, which can be coupled and modulated into the micro-optical circuit by the THz light probe, in which the reflected signals are obtained via the signal direct detection or the drop port output signals, in which the different synapses and signals can be distinguished by using the filtering devices, where the variables such as wavelengths (frequencies), signal amplitudes and signal forms can be investigated. The use of the proposed concept for brain signal monitoring and encoding, sub-consciousness investigation, and human ad hoc networks is modeled and discussed |
