A unique delayed self-inhibitory pathway mediated by layer 5 Martinotti Cells was studied in a biologically inspired neural network simulation. Inclusion of this pathway along with layer 5 basket cell lateral inhibition caused balanced competitive learning, which led to the formation of neuronal clusters as were indeed reported in the same region. Martinotti pathway proves to act as a learning "conscience," causing overly successful regions in the network to restrict themselves and let others fire. It thus spreads connectivity more evenly throughout the net and solves the "dead unit" problem of clustering algorithms in a local and biologically plausible manner.
在一个受生物启发的神经网络模拟中，研究了一种由 5 层 Martinotti 细胞介导的独特的延迟自抑制途径。将这条途径与 5 层 basket 细胞的侧抑制结合在一起，导致了平衡竞争学习，从而形成了神经元簇，这与同一区域的实际报道一致。Martinotti 途径证明可以作为学习的“良心”，使网络中过于成功的区域自我限制，让其他区域活跃。因此，它以局部和合理的生物方式更均匀地扩展了网络的连接性，并解决了聚类算法的“死单元”问题。
