• It is still correlational
• We are only able to look at correlation
• We are able to only see correlation
• It isn't causal
Slide 29
• We produce way more synapses that we actually use and therefore need
• At particular times in development, there is an increase and then a sudden decrease in grey
matter synaptic pruning is good because it makes connections between neurons more efficient
• As you continue to use the most efficient and direct synapses, the others are pruned
• Where and when synaptic pruning in the brain is correlated in changes in cognitive functioning
• Over-proliferation is when there is an increase

Document Summary
It is still correlational: we are only able to look at correlation, we are able to only see correlation. Slide 30: makes sure that the information we want to go from this neuron to this neuron is happening. Just before birth we have an increase and then a: there is a correlation between myelination and pruning. It is a correlatio(cid:374), (cid:449)e do(cid:374)"t k(cid:374)o(cid:449) if its causi(cid:374)g that type of cog(cid:374)itio(cid:374) Limbic cortex: rewards, what incentive brings us to approach. Slide 33: know the 3 parts of the pfc, pfc isn"t full matured in adolescents. Slide 34: activity is becoming more focused in pfc, as activation is becoming more focused, there are more connections being made. Slide 35: ntr levels are changing, what motivates us. Limbic system is fully matured by early adolescents, but not the pfc. Slide 36: part of brain that puts the breaks on the behaviour is not fully developed.
