The EEG (electroencephalogram) head net consists of 128 passive electrodes that are able to detect the electrical field produced by groups of neurons in the brain. This gives the researchers a window into which parts of the brain participate in tasks involving crawling and how the different brain regions change their involvement with learning and development.

The researchers hope that this interaction will encourage the practice of crawling-like movements and the development of the infant's "mental map" of his surrounding environment.
