Subject: Concerning the brain growth of infants

When newborns are growing, they spend about 90 % of their time sleeping, 10% 
awake. The sleep is a necessary time for them to develop synaptic connections. 
The question is: Do these stimuli come from inside the babies or from outside 
them? If from the outside, then how can the brain grow with such little input? 
(I.e. how does a child mentally digest what it does not yet understand?) If 
from the inside, then where do these connections come from in the first place?

Are we pre-programmed somehow?



Thanks for your time,
