a LTP/STP behaviors under 9 and 2 LCP spikes. b Variation of An/A1 index with increasing the LCP pulse numbers. c EPSC in response to multiple LCP pulses with various wavelengths. d EPSC in response to 395 nm LCP with different power intensities and fixed frequency of 1 Hz. e Spike-frequency-dependent EPSC triggered by a sequence of 9 LCP spikes. f Learning and memory process in neuromorphic vision system. g Learning-experience behavior imitated by the PAS device under 395 nm LCP and RCP illumination. The sample is 1D-S/SWNTs-based PAS.
