On-Chip Training Spiking Neural Networks Using Approximated Backpropagation With Analog Synaptic Devices.

abstract：:With emerging evidence showing a wide distribution of secretin (SCT) and its receptor (SCTR) in the central nervous system (CNS), the putative neuropeptide role of SCT has become more appreciated since the disruption of SCT/SCTR axis affects various neural functions. This mini review thus focuses on the effects of SCT...
