Abstract

The model proposed puts forward a hypothesis on how some pacemaker neurons learn to fire at the frequency imposed by the stimulation. It builds on previous developments in two separate research fields: neural modelling and neuronal learning theory, providing an electrophysiological model of neuronal learning. Simulation results are shown to be in qualitative agreement with experimental data reported for Aplysia and crayfish. The analytical study of the PRC reveals that the postulated learning rule tends to favour the emergence of simple entrainment ratios. The model is worth consideration not only because of its autonomous functioning, described in this paper, but also because it constitutes a suitable building-block for a net aimed at reproducing the temporal-pattern learning phenomena shown by some neural structures.

摘要

所提出的模型就一些起搏器神经元如何学会以刺激所施加的频率放电提出了一个假设。它基于两个独立研究领域的先前进展:神经建模和神经元学习理论,提供了一个神经元学习的电生理模型。模拟结果显示与针对海兔和小龙虾报道的实验数据在定性上一致。对相位响应曲线的分析研究表明,假定的学习规则倾向于促进简单夹带比率的出现。该模型不仅因其本文所描述的自主功能值得考虑,还因为它构成了一个合适的构建模块,可用于构建一个旨在重现某些神经结构所表现出的时间模式学习现象的网络。
