Abstract

Functional microcircuits model the coordinated activity of neurons and play an important role in physiological computation and behaviors. Most existing methods to learn microcircuit structures are correlation-based and often generate dense microcircuits that cannot distinguish between direct and indirect association. We treat microcircuit structure learning as a Markov blanket discovery problem and propose Bayesian Coherence Analysis (BCA) which utilizes a Bayesian network architecture called Bayesian network with inverse-tree structure to efficiently and effectively detect Markov blankets for high-dimensional neural activity data. BCA achieved balanced sensitivity and specificity on simulated data. For the real-world anterior lateral motor cortex study, BCA identified microcircuit subtypes that predicted trial types with an accuracy of 0.92. BCA is a powerful method for microcircuit structure learning.

微电路结构学习的贝叶斯相干分析。
功能微电路模拟神经元的协调活动,在生理计算和行为中起着重要作用。大多数现有的学习微电路结构的方法都是基于相关性的,并且经常产生不能区分直接和间接关联的密集微电路。我们将微电路结构学习视为一个马尔可夫毯子发现问题,并提出了贝叶斯相干分析(BCA),该分析利用贝叶斯网络结构(称为反树结构贝叶斯网络)高效有效地检测高维神经活动数据的马尔可夫毯子。BCA对模拟数据的敏感性和特异性达到平衡。对于真实世界的前外侧运动皮层研究,BCA识别出预测试验类型的微电路亚型,准确率为0.92。BCA是一种有效的微电路结构学习方法。
