| summary | The developing brain does not simply consist of poorly formed adult circuits. Rather specialized neural configurations give rise to important network properties that emphasize plasticity and synapse formation at the expense of information processing. In the visual system, thalamocortical networks shift between these two configurations just before birth in humans, and just before eye-opening in rodents. This shift is largely a result of synaptic changes between cortex, relay thalamus and the thalamic reticular nucleus which reduce excitability in thalamus, changing its function from amplifier to relay, allowing for visual processing to emerge. |
