Synaptic density in the primary visual cortex of infants peaks by the seventh or eighth postnatal month and then undergoes a process of pruning, where excess synapses are eliminated. This is different from the development and myelination patterns of the prefrontal cortex, which continue to mature well into adolescence and early adulthood.
