Introduced to the concept/theory of natural selection and brain evolution today during a video. Take a baby who learns to reach out and grab something, they dont do it straight away but "learn" how to do so. They do this by the trying many possible ways to strech and grab which may or may not work. The synapses in the brain are strenghtened or weakend depending or not the output is judged to have a positive or negative effect i.e if the baby succeds the synapses are strengthend and the likehood of the same impulse passing down thesse syanptic pathwyas is increased,so the likehood of the same action is increased, over time the action is learnt. Though it highlights the question how does the brain know which values are classed as good and bad without previous knowledge. JUst seeing if anyone has any thoughts?http://en.wikipedia.org/wiki/Gerald_Edelman#Theory_of_consciousness
Surely the brain will realise that there is no punishment from the movement so there is no reason why they shouldn't learn it. However, if there was some form of punishment it could cause the baby to forget because it has no benefit and provides an experience that the baby doesn't want to experience again.
What are your thoughts?
