Sensory deprivation, such as a lack of visual stimulation soon after birth, can lead to developmental abnormalities in the brain, but the exact mechanisms that underlie this system remain unclear. In October 3 Nature, Florian Engert and colleagues at the University of California, Berkeley, USA, show that moving visual stimuli can rapidly induce directional sensitivity in developing neural circuits and thus influence brain development (Nature, 419: 470-475, October 3, 2002.).
