Like this pattern of pulses here actually means "baby's face," and so when the brain gets this pattern of pulses, it knows that what was out there was a baby's face, and if it got a different pattern it would know that what was out there was, say, a dog, or another pattern would be a house.
Questo schema di impulsi significa proprio "volto di bimbo", e quando gli impulsi arrivano al cervello, questo capisce che si trova di fronte al viso di un bambino, e se avesse ricevuto uno schema di impulsi diverso, magari l'avrebbe associato a un cane o forse a un cavallo.
