Previous structural searches on spiking neural networks have not considered the types of neurons, which limits the diversity of spiking neural networks. 大脑包含不同类型的神经元,它们通过动态协作形成不同的神经环路,以实现不同的认知功能。先前对SNN进行的结构搜索未考虑神经元的类型,这限制了SNN的多样性。
Neurons,Biological neural networks,Oscillators,SPICE,Sensors,Integrated circuit modeling,Quantization (signal)We propose a compact STT-MRAM spiking neuron circuit that is a critical component of future hardware neural networks for accelerating deep learning. A SPICE compact model was established for the ...
Quantitative Biology - Neurons and CognitionWe demonstrate a spiking neural network for navigation motivated by the chemotaxis network of Caenorhabditis elegans. Our network uses information regarding temporal gradients in the tracking variable's concentration to make navigational decisions. The gradient ...
We present a model of attentional routing called the Attentional Routing Circuit (ARC) that extends an existing model of spiking neurons with dendritic nonlinearities. Specifically, we employ the Poirazi et al. (2003) pyramidal neuron in a population coding framework. ARC demonstrates that the ...

Placebo effects are notable demonstrations of mind–body interactions1,2. During pain perception, in the absence of any treatment, an expectation of pain relief can reduce the experience of pain—a phenomenon known as placebo analgesia3–6. However, desp
Understanding the relationship between genotype and neuronal circuit phenotype necessitates an integrated view of genetics, development, plasticity and learning. Challenging the prevailing notion that emphasizes learning and plasticity as primary drivers
Inspired by animal research, realistic computational models of axon activation have brought the excitation hypothesis to life. It proposes that high-frequency stimulation may directly activate local neurons, and even if it fails to evoke local spiking, it may excite downstream structures through ...
Glass micropipettes are widely used to record neural activity from single neurons or clusters of neurons extracellularly in live animals. However, to date, there has been no comprehensive study of noise in extracellular recordings with glass micropipettes. The purpose of this work was to assess va...
Using movable silicon probes, we recorded the firing of 2,417 LH neurons while mice were engaging in F, S or E in a free-choice model (Fig. 1a and Extended Data Fig. 1a,b). As reported previously1,17, individual LH neurons increased or, less often, decreased their firing rate during...
