The model simulated. L2/3 PC is a layer 2/3 pyramidal cell. The thick line above the pyramidal cell body is the dendrite, receiving inputs from the previous cortical area that operate by competitive learning using the synapses w^comp; from the recurrent collateral that operate as an attractor network using synapses w^rec; and back-projections from higher cortical areas for memory recall and top–down attention that operate by pattern association learning using the synapses w^bp. 1–6: the layers of the neocortex
