Topic: cortical lateral interactions

In ferret visual cortex, spontaneous activity before eye-opening is organised into large-scale, modular patterns in the absence of long-range projections. This correlated activity reveals endogenous networks that predict aspects of future orientation selectivity. Previous modelling works have shown that the long-range correlations observed in these networks can arise from locally connected neurons through multi-synaptic interactions. Here we seek to map the structure of cortical lateral interactions through localised perturbations in vivo.We first constructed a rectified recurrent neural netwo
