神经元作为神经系统的基本单元,提供了人类认知的基本信息功能处理机制。文章通过对神经元及其模型进行计算分析,指出了神经元内离子对刺激信息的反应,在此基础上阐释了误差驱动任务学习与BP学习法,最后文章对神经元的计算启示给出了解读。文章表明,脑认知是动态的表征,其非线性地处理认知现象,并指出计算神经科学在解读大脑处理信息上正在尝试突破,具有重要的研究意义和价值。
As the basic unit of the nervous system, neuron provides the basic mechanism of information processing for human cognition. The paper elucidates the computational interpretation about neurons and their models, points out ions' response to stimulus information in neurons. Based on this, the paper interprets error - driven task learning and back propagation. Finally, the paper analyzes computational enlightenment of neurons. It shows that brain cogni- tion is dynamic characterization and processes nonlinearly cognitive phenomenon. Computational neuroscience is try- ing some break through in interpreting how the brain processes information, which is of great significance and value.
