i had wondered the analogue of microtubule computation in HTMs. microtubules, as measured, are operating at several space scale magnitudes smaller and faster than individual neurons. whether or not they influence macroscopic neural activity, the cylindrical matrices can store and process additional memory bits "in-between" and "inside-of" neurons. their design might be adapted somehow. here's some notes
--- https://en.wikipedia.org/wiki/Microtubule In January 2014, Hameroff and Penrose announced that the discovery of quantum vibrations inmicrotubules by Anirban Bandyopadhyay of the National Institute for Materials Science in Japan in March 2013[20] confirms the hypothesis of the Orch-OR theory.[10][21] http://www.ncbi.nlm.nih.gov/pubmed/23567633 this is [20] ther Moreover, the transmitted ac power and the transient fluorescence decay (single photon count) are independent of the microtubule length. Even more remarkable is the fact that the microtubule nanowire is more conducting than a single protein molecule that constitutes the nanowire. Microtubule's vibrational peaks condense to a single mode that controls the emergence of size independent electronic/optical properties, and automated noise alleviation, which disappear when the atomic water core is released from the inner cylinder. A single microtubule, acts just like a single molecule oscillator, the frequency ranges of three resonance bands are (10^4 ~ 10^10 Hz, gap in order ~6) Triplet 1 (15–20 kHz, 25–80 kHz, 100–300 kHz), Triplet 2 (10–19 MHz, 20–40 MHz, 100–228 MHz), Triplet 3 (1–5 GHz, 7–10 GHz, 15–30 GHz). Microtubule is electrical insulator (~300 mega Ohms), however, at particular ac frequencies, the dc conductivity decreases several orders of magnitude to a few kilohms.[32] These frequencies are termed as electromagnetic resonance frequency. Sahu et al exhibited multi-level memory switching properties storing as much as ~500 bits, reversible switching like Random Access Memory (RAM) devices. Single molecule multi-level memory switching is an advanced atomic scale measurement technique,[33] which exhibits massively parallel computing.[34] http://arxiv.org/pdf/1110.5844v1.pdf Massively parallel computing on an organic molecular layer https://github.com/Marge-m/microtubules http://www.hameroff.com/ultimatecomputing/index.html On Sun, Jan 18, 2015 at 2:32 PM, Fergal Byrne <[email protected]> wrote: > > Jeff should give that guy a call.
