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.
Ta grupa impulsów to dosłownie "twarz dziecka", więc otrzymując taki wzór impulsów, mózg wie, że była to twarz dziecka. Gdyby otrzymał inny wzór, wiedziałby, że to pies, wiedziałby, że to pies, a jeszcze inny - dom.
