Topic: angiogenesis

By continuously producing electrical signals, neurones are amongst the most energy-demanding cells in the organism. Resting ionic levels are restored via metabolic pumps that receive the necessary energy from oxygen supplied by blood vessels. Intense spontaneous neural activity is omnipresent in the developing CNS. It occurs during short, well-defined periods that coincide precisely with the timing of angiogenesis. Such coincidence cannot be random; there must be a universal mechanism triggering spontaneous activity concurrently with blood vessels invading neural territories for the first time
