Like a title from a sci-fi horror movie – scientists have succeeded in bridging the critical gap between the biological and electronic worlds. A study published in the journal Nature Electronics describes in detail “hybrid biocomputer” combining lab-grown human brain tissue with conventional circuitry and artificial intelligence. A system called Brainoware learned to identify voices with 78% accuracy. This could one day lead to the creation of silicon microchips linked to neurons.
Brainoware combines brain organelles (clusters of human stem cells transformed into “mini brains”) with common electronic circuits. To make it, scientists placed a single organoid on a plate containing thousands of electrodes. The circuits that communicate with the brain organoid convert the information they want to input into a pattern of electrical impulses.
Brain tissue then teaches and communicates with technology. A sensor in the electronic field detects the response of the mini-cerebellum, which is decoded by a trained machine learning algorithm. In other words, with the help of artificial intelligence, neurons and electronics combine into a single (yet extremely basic) problem-solving biomacro.
The researchers taught the computer-brain system recognize human voices. Brainoware trained on 240 recordings of eight people speaking and translated the sound into an electrical form, which they then presented to the organoid. The organic part responded differently to each voice, creating a pattern of neural activity that the AI learned to understand. That’s how Brainoware learned identify voices with 78% accuracy.
The team sees this work as a proof of concept rather than something with any imminent practical use. Although previous studies have shown that two-dimensional cultures of neuronal cells can handle similar tasks, this is first trial run using trained human brain cells. It could be about foundation for biological computerswhere the speed and efficiency of the human brain will be used to create super-powerful artificial intelligence.
Kama kichwa kutoka kwa filamu ya kutisha ya sayansi ya uwongo <unk> wanasayansi wamefanikiwa kuziba pengo muhimu kati ya ulimwengu wa kibiolojia na wa elektroniki. Utafiti uliochapishwa katika jarida la Nature Electronics unaelezea kwa undani "kompyuta ya kibiolojia ya mseto" inayochanganya tishu ya ubongo wa binadamu iliyokuzwa kwenye maabara na mzunguko wa kawaida na akili bandia. BrainWare ni mfumo wa kompyuta unaotumia sauti za watu kwa usahihi wa asilimia 78. Hii inaweza siku moja kusababisha uundaji wa microchips silicon kushikamana na neurons. Brainoware inachanganya organelles za ubongo (makundi ya chembe za msingi za binadamu zilizobadilishwa kuwa "ubongo mdogo") na mizunguko ya kawaida ya elektroniki. Ili kuifanya, wanasayansi waliweka organoid moja kwenye sahani yenye maelfu ya elektroni. Mzunguko unaowasiliana na organolipid ya ubongo hubadilisha habari wanayotaka kuingiza katika muundo wa msukumo wa umeme. Kisha tishu za ubongo hufundisha na kuwasiliana na tekinolojia. Sensor katika uwanja wa elektroniki hugundua majibu ya mini-cerebellum, ambayo ni decoded na mafunzo ya mashine kujifunza algorithm. Kwa maneno mengine, kwa msaada wa akili bandia, neuroni na umeme huunganishwa katika biomacro moja (lakini ya msingi sana) ya kutatua tatizo. Watafiti hao walimfundisha mfumo wa ubongo wa kompyuta utambue sauti za kibinadamu. BrainWare ilijifunza juu ya rekodi 240 za watu wanane wanaozungumza na kutafsiri sauti hiyo kuwa fomu ya umeme, ambayo kisha waliwasilisha kwa organoid. Sehemu ya kikaboni ilijibu kwa njia tofauti kwa kila sauti, ikiunda muundo wa shughuli za neva ambazo AI ilijifunza kuelewa. BrainWare imepata uwezo wa kutambua sauti kwa usahihi wa 78%. Timu inaona kazi hii kama uthibitisho wa dhana badala ya kitu na matumizi yoyote ya vitendo ya karibu. Ingawa utafiti wa awali umeonyesha kwamba tamaduni mbili za neuronal zinaweza kushughulikia kazi kama hizo, hii ni jaribio la kwanza kutumia seli za ubongo wa binadamu zilizozoezwa. "Kama msingi wa kompyuta za kibiolojia, ambapo kasi na ufanisi wa ubongo wa binadamu utatumiwa kuunda akili ya bandia yenye nguvu sana."""
