Impacts of nanoscale events on the neural functions of lives
Shengyong Xu and Jingjing Xu
Peking University, China
In this talk, we will show that synapse may play a crucial role in memory function and brain working mechanism. 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 2 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 2 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. These kinds 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. Such a scenario explains better phenomena observed in
the nature, such as the simultaneous phenomenon observed in prey behavior of flytraps and discharge of electric eels, where
a big amount of reactors in a biosystem almost simultaneously respond to a single input signal and complete reactions within
milliseconds. We will also discuss the impacts of nanoscale events on the neural functions of lives.

of synapses: Chemical, Mixed and Electrical
synapses. Under certain conditions, these synapse
may transform from one type to the other, thus
leading to significant impacts on the neural functions
of lives, e.g., in establishing a piece of memory.
