Developmental plasticity

[kristiann]

Hi guys, I've been looking through the various notes that I have, and I've come across two ways people set out developmental plasticity
1. proliferation, migration, circuit formation, circuit pruning, myelination

or

2. synaptogenesis, synaptic pruning, neural migration, myelination

Which one is correct, and why?
thanks

Hi there!

You can have a look here, it might help you out!

Stages of developmental plasticity

[slothpomba]

I believe that they refer to more or less the same thing, people call that orange fruit either a Cantelopue or a Rock melon, same object, different term.

It's been awhile since i've done developmental biology (i can pull up my notes if need be) but thats basically the short and skinny of it. "Synaptogenesis"likely encompasses terms one and three in the other definition. Even if you knew zero biology or psychology, it isn't difficult to noodle out, lets work backwards:

Myelination - How can you myelinate neurons if there are no neurons around? Especially in their final configuration.

Pruning - It can only happen when there are obviously neurons formed and only when there are an excess of them!

Which leads us to the initial stages of circuit formation and proliferation.
