Abstract: Abstract In the primary visual cortex, the development of orientation selectivity is influenced by patterns of neural activity. The introduction of artificially correlated activity into the visual pathway (through synchronous activation of retinal ganglion cell axons in the optic nerve) substantially weakens the orientation selectivity of neurons in superficial and deep cortical layers. This is consistent with activity having an instructive role in shaping cortical neuron receptive field tuning properties.
