Topic: L-events

Brain circuits in mouse pups develop and mature extensively during the first few weeks of life. During early postnatal development, sensory cortices experience patterned spontaneous activity which is known to refine neural connectivity, preparing the animal to engage in sensorimotor tasks immediately upon ear and eye opening (∼P4 and ∼P15, respectively). In primary visual cortex (V1), spontaneous activity originates from two sources, from the retina relayed by thalamus and intrinsically generated in the cortex. Spontaneous events from these two sources have different spatiotemporal properties:
