Abstract
In this talk, we will show that synapse may play a crucial role in memory function and brain working mechanism [1,2]. We presented a model, stating that data for memory are stored and retrieved in the form of a strongly connected network of neurosomes, patterns of which form topological “2D codes” in layered neurons in a brain. In different reaction modes, a chemical synapse or a mixed synapse could turn into an electrical synapse. These transitions, together with an echoing process between two neighboring layers of neurosomes could establish temporary memory and long-term memory information in the forms of neurosome-based 2D codes. The size of a synapse is only around one micrometer, and the gap between two connecting synapses is of nanometer scale. Why some connections could last for 10-50 years, while some others only last for seconds? Are there reverse processes so that strongly connected synapses could depart, thus leading to fresh functions of a brain? These are interesting open questions.
We will also show that a transient ion current passing through a protein channel embedded in a membrane creates a pulsed, soliton-like electromagnetic (EM) wave. This kind of EM pulses propagate well in the networks of dielectric phosphorous lipid bilayers. In an electrolyte-membrane-electrolyte structure defined as soft-material waveguide, an EM wave may transmit with a higher efficiency than in cytoplasm [3,4]. Such a scenario explains better some unique phenomena observed in the nature, such as the “simultaneous phenomenon” observed in prey behavior of flytraps and discharge of electric ells, where a big amount of reactors in a biosystem almost simultaneously respond to a single input signal and complete reactions within milliseconds .
We will discuss the impacts of nanoscale events on the neural functions of lives.
