Explore groundbreaking research on DNA-based chemical neurons that mimic biological sensory systems in this 23-minute conference presentation. Discover how researchers have developed thermosensory chemical neurons that encode thermal signals in the temporal domain, similar to cold nociceptive neurons in living organisms. Learn about the innovative design where these chemical neurons remain at rest at high temperatures but begin producing spikes of chemical activity when exposed to low temperatures, with firing rates that directly correspond to temperature changes. Examine the bifurcation patterns that mirror those found in biological thermosensory neurons, demonstrating remarkable robustness and avoiding artifacts of simpler systems. Understand how these chemical neurons can function as digital communication channels with high fidelity and thermal noise resilience, and see how they can be miniaturized to operate tens of thousands of units in analog mode for precise temperature coding. Gain insights into the potential for creating spiking chemical networks that could process information similarly to nervous systems in complex organisms, opening new avenues for recurrent molecular computations and bio-inspired computing systems.
