When people talk about "re-wiring" your brain, what they actually are talking about is NEUROPLASTICITY: the brain's ability to create new neural pathways and re-structure existing neural pathways. In this episode I explain how neural pathways work; how synaptic reflexes work; how semantic memory and habituation influence our brains and neural pathways; and, not least, how we can maintain our brain's function AND increase our neuroplasticity.
