Microtubules and neuronal nanobioelectronics

Aromatic amino acids in proteins, (tryptophan, tyrosine, histidine and phenylalanine) have electron resonant ring structures in which electrons are mobile and delocalizable. Electron transport is examined in these complexes with electrons hopping or tunneling between aromatics that have less than 2 nm separations. Microtubule cylindrical lattices form distinct helical pattern topologies that can perform information processing, information propagation, computing and memory storage within cells. The microtubule patterns correspond with binding patterns of microtubule-associated proteins. These proteins correspond to cytoskeletal and cellular structure and function. This paper reports a concept of information propagation and information processing in microtubules from an electronics viewpoint. Analysis and modeling are performed in this paper.
