Abstract: Advanced studies are now expected under cooperation of medical and electrophysical researchers. Actual operation of neurons remains much unknown. Neurons and unicellular organisms are controlled by mutual interactions and external conditions. She will present recent studies in neurons referring conventional studies of experiments. Novel result of studies will be given based on dynamic modelling in time-space domain. Electrical analysis is then given for bipolar potential generation in a single neuron. This model is brought by studies in unicellular organisms and semiconductor physics. She will present basis of the original models given from knowledge in liquid junctions and dynamic zones induced in cell cytoplasm. Generation of bipolar action potential is needed to compose reliable systems with little power consumption. Unicellular organisms utilize bipolar potentials for motion of cilia of paramecium, tentacle of noctiluca, and so on.
Brief Biography of the Speaker: Yumi Takizawa received the Ph.D. degree from the University of Tokyo in 1994.
