摘 要：By measuring fundamental electronic properties of a single brain microtubule, the researchers have found that it learns approximatley 500 states by loss-less ferroelectric memory switching. They confirm that a single microtubule is a resonator with large quality factor, simultaneously operating with three distinct resonance bands, in the kHz, MHz and in the GHz frequency domain. It operates in the pico/femto-watt (1mV, 1pA) domain. They have underpinned its wireless communication and information processing potential that could unravel a hitherto unknown physical picture of the biological systems and trigger building of bio-inspired tunable multi-band resonators.
