Answer 2

whole brain, brain circuits, brain regions, cells (neurones & Glia), Orangelles (synapses & axons), protein complexes, proteins, genes.

Question 3

Answer 3

neurodevelopment genetics, neurophysiology, behaviour, typical & atypical functioning.

Question 4

what are some facts about the brain and neurogenesis.

Answer 4

at birth brain weights 350g, mature brain weighs about 1300g. there are about 85 billion neurones & trillions of synapses. at peak neurogenesis around 250k neurones born per min
