A neural circuit is a population of neurons interconnected by synapses to carry out a specific function when activated. [1] Multiple neural circuits interconnect with one another to form large scale brain networks .

Integrating studies of the structure, function, development, and evolution of neuronal circuits will enable a deeper understanding of nervous system organization beyond the level of individual neurons. Exploration of neuronal circuit architectures will also continue to inspire important advances in artificial intelligence.

These three classes—afferent neurons, efferent neurons, and interneurons—are the basic constituents of all neural circuits. Neural circuits are both anatomical and functional entities. A simple example is the circuit that subserves the myotatic (or “knee-jerk”) spinal reflex .

2021年9月3日， Science 杂志重磅推出了顶级神经科学家骆利群院士的综述文章： Architectures of neuronal circuits。 这篇综述提炼出了关键的环路建构模式，并指出其潜在的功能以及它们是如何在进化发育中涌现出来的。 骆利群院士通过把神经元比喻为字母，微环路比喻为单词，神经环路比喻为句子，大脑比喻为整篇文章，深入浅出地解释了 神经环路架构的一般性原理。 值得一提的是，骆利群院士还单独编写了斯坦福大学经典教科书-- 《神经科学原理》。 早在一个世纪以 …

While individual neurons are the basic unit of the nervous system, they process information by working together in neuronal circuits with specific patterns of synaptic connectivity. Here we review common circuit motifs and architectural plans …

2021年9月16日 · “回旋式神经网络”（convolutional neural networks（包含回旋计算且具有深度结构的前馈神经网络，是深度学习的代表算法之一）的设计就借鉴了拓扑映射，极大地减少了调整人工神经网络所需的变量数，从而加快了计算速度【4, 15】。

2024年1月3日 · Synapses are a key component of neural circuits, facilitating rapid and specific signalling between neurons. Synaptic engineering — the synthetic insertion of new synaptic connections...

In the nervous system, neurons exhibit diverse morphologies and branching patterns, allowing rich compartmentalization within individual cells and complex synaptic interactions among groups of cells. In this review, we summarize work detailing how …

A neural circuit is a population of neurons interconnected by synapses to carry out a specific function when activated. What makes our nervous system such a fantastic device is not that it has 100 billion neurons, but that these nerve cells are capable of communicating with each other in a highly interactive set of neuronal networks.

2021年9月3日 · Although individual neurons are the basic unit of the nervous system, they process information by working together in neuronal circuits with specific patterns of synaptic connectivity. Here, I review common circuit motifs and architectural plans used in diverse brain regions and animal species.
