Define synaptogenesis
New synapses formed between neurons- exuberant before birth + post natal (possibly one million new synapses created). Produces more than necessary (twice as many in a 3 year old than adult).
What happens after 3 years?
Synaptic loss and neurons used most experiencing greater neurotransmitter activity where it strengthens synapses. Inactive synapses die- pruned.
What do myelinated neurons allow?
Allow them to conduct electrical impulses more efficiently in parts of the nervous system where this is crucial.
What’s the point of synaptic pruning?
Creates organisation in the brain, so areas become specialised for certain functions.
