This communication gives rise to temporal in-phase or out-of-phase synchronization phenomena between the transmitter (the BZ reaction) and the receiver (the photochromic and luminescent compound), analogously as does the chemical code of neurotransmitters within networks of real neurons to real neuronal networks. This approach allows the mimicry of the liquid state of the brain, and the encoding of information by UV/visible radiation guarantees swift propagation of messages and easy modulation in intensity.

Abstract
Artificial intelligence (AI) significantly impacts our society since it is used in economics, medicine, security, and basic and applied science. A promising approach to AI development is Neuromorphic engineering. It aims to mimic human intelligence by implementing artificial neurons (ANs) and their networks in software and hardware. We propose a contribution to neuromorphic engineering based on solutions of specific nonlinear chemical systems in wetware, which can simulate the dynamics of real neurons . The use of chemical systems maintained under out-of-equilibrium conditions allows us to mimic some performances of the human brain. Specifically, in this work, we use UV-visible radiation as a signal to study the optical communication between the Belousov-Zhabotinsky (BZ) reaction and photochromic and luminescent materials. This study demonstrates that UV-visible radiation can be exploited as a signal for communication among neuronal surrogates in oscillatory and photo-excitable regimes. This communication gives rise to temporal in-phase or out-of-phase synchronization phenomena between the transmitter (the BZ reaction) and the receiver (the photochromic and luminescent compound), analogously as does the chemical code of neurotransmitters within networks of real neurons to real neuronal networks. This approach allows the mimicry of the liquid state of the brain, and the encoding of information by UV/visible radiation guarantees swift propagation of messages and easy modulation in intensity.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
