A Biomimetic 2D Transistor for Audiomorphic Computing

This 10-page article, from Nature Communications, discusses research related to neuromorphic computing. This research involves "... a biomimetic audiomorphic device that captures the neurobiological architecture and computational map inside the auditory cortex of barn owl..." Mimicking barn owls "super sensory neural architectures and associated algorithms through innovative solid-state devices and circuits might provide an alternative route towards energy efficient neuromorphic computing." Researchers created a transistor-based device using molybdenum disulfide (MoS2) that simulates how barn owls detect tiny differences in sound arrival time, helping them localize sound. This allowed the device to perform both analog and digital computations inspired by the owls auditory system.

This article includes the following sections: Abstract; Introduction; Results - Neural map and compute algorithm in barn owl, Artificial coincident detector neuron, Construction of neural auditory computational map, Artificial time delay neurons, and Neuroplasticity; Discussion; Methods; and more.
