Why does the human brain take so long to develop? Scientists find a gene that may provide a clue about our extraordinary brainpower, cognitive abilities

A human-specific gene influences brain immune cell development. These cells, called microglia, mature much slower than in mice. This extended maturation period may help build complex neural connections. The gene SRGAP2 appears to synchronize this process with neuron development. This finding offers new insights into human brain evolution and disorders.
