File:Spatiotemporal recognition capabilities of the synaptic transistor.webp

English: "a Illustration of a biological neuron with multiple dendrites. b Postsynaptic current measured by applying a spike train (5 V, 50 ms, 5 spikes) to the two gates respectively (Gate1: main gate; Gate2: minor gate). Inset shows a close-up photograph of the device. These two gates were assigned to different sensory modalities (assignment of perceptual weights). c Postsynaptic current (PSC) of the device when a series of pairwise spike trains with distinct timing (temporal delay Δt: −1.0, −0.5, 0, 0.5, 1.0 s) were applied to the two gates (Gate1 and Gate2). d Definition of event duration (N; unitless), spike number (N1, N2), mean firing rate (f1, f2; relative value, unitless), and synaptic response (ΔPSC) under the stimuli of two spike trains with temporal delay (Δt). Event duration was measured by spikes. e Mean firing rates of the two spike trains corresponding to the five cases in (c). f Synaptic response (ΔPSC) of the device corresponding to the five cases in (c). Spatiotemporal patterns of the two spike trains were well classified in multiple trials (n = 5), and the error bars in the figure represent the standard deviation (SD)."
