neurony maju vnutri "kostru" z mikrotubulov (MT), typci uz dlhsie vymyslaju ze je dolezita pri spracovani informacii a kodovani pamete ale konecne to zacina davat zmysel http://www.ploscompbiol.org/article/info:doi/10.1371/journal.pcbi.1002421 Motor proteins dynein and kinesin move (in opposite directions) along MTs (using ATP as fuel) to transport and deliver components and precursors to specific synaptic locations. While MTs are assumed to function as passive guides, like railroad tracks, for motor proteins, the guidance mechanism by which they follow specific paths, e.g. through branching dendrites and interrupted MTs is unknown. Phosphorylation patterns on MT lattices could guide motor proteins to specific locations ... Clusters of phosphorylated tubulin, and/or MAP attachment may serve as logic gates for propagating information. .. The combination of XOR and AND logic gates forms a universal set for computation in which all other logic gates (NOT, OR etc.) can be conceived. ... tubulin states interact and update coherently at discrete time steps attributed to theorized or experimentally-observed coherent MT resonances, e.g. in the low megahertz range, potentially resulting in millions of synchronized updates per second. |
