Wiring the Brain: Steps in Neuronal Morphogenesis

NEURO-VL@XLK

Neuronal morphogenesis is a multi-step process of transforming a neuroblast that just exited the cell cycle into a mature neuron. Morphological transformation changes a rounded or oval shaped cell into a neuron with its characteristic morphology that may include a particular cell shape (e.g. pyramidal), hundreds of processes (axons and dendrites), and up to tens of thousands of synaptic connections.

Which of the following lists the steps of neuronal morphogenesis in the correct order?
