The specificity of cortical neuron connections creates columns of functionally similar neurons spanning from the pia to the white matter1,2,3,4,5,6. Here we investigate whether there is an additional, finer level of specificity that creates subnetworks of excitatory neurons within functional columns. We tested for fine-scale specificity of connections to cortical layer 2/3 pyramidal neurons in rat visual cortex by using cross-correlation analyses of synaptic currents evoked by photostimulation… CONTINUE READING
