Nonlinear Dendritic Coincidence Detection for Supervised Learning

Abstract: Cortical pyramidal neurons have a complex dendritic anatomy, whose function is an active research field. In particular, the segregation between its soma and the apical dendritic tree is believed to play an active role in processing feed-forward sensory information and top-down or feedback signals. In this work, we use a simple two-compartment model accounting for the nonlinear interactions between basal and apical input streams and show that standard unsupervised Hebbian learning rules in the basal compartment… Show more

“…Naturally, depending on the information that is encoded in the feedback signals, different internal plasticity rules are required. In [159], we showed how a simple Hebbian learning rule in combination with a dual homeostatic mechanism in a simple pyramidal compartment model allows feedback signal to serve as target signals for the plasticity in the basal synaptic weights. Before presenting this work in detail, we will first review the anatomical basics that motivates the theoretical work on biologically plausible learning in deep neural networks, which is summarized thereafter.…”
