Using high-density electroencephalography in 5- to 11-month-old infants and a looming stimulus approaching under three different accelerations, we investigated how the young human nervous system extracts and processes information for impending collision. Here we show that infants' looming related brain activity is characterized by theta oscillations. Source analyses reveal clear localised activity in the visual cortex. Analysing the temporal dynamics of the source waveform, we provide evidence that the temporal structure of different looming stimuli is sustained during processing in the more mature infant brain, providing infants with increasingly veridical time-to-collision information about looming danger as they grow older and become mobile. http://precedings.nature.com/documents/2917/version/1 Tue, 03 Mar 2009 08:50:42 UTC Temporal dynamics of travelling theta wave activity in infants responding to visual looming hdl:10101/npre.2009.2917.1 2009-03-03 Ruud F.
