Wiring the Brain: Synapse Formation in the Development Timeline

NEURO-JKLIES

Development of the brain consists of a number of discreet, albeit partially overlapping, steps. Formation of synaptic connections is a central process (or step) in the wiring of the brain.

Which of the following processes in brain development may overlap with the formation of synaptic connections?

A

Formation of synaptic connections takes place immediately after neural induction, with which it partially overlaps.

B

Formation of synaptic connections is followed by neuronal migration, with which it partially overlaps.

C

Formation of synaptic connections is followed by cell death of neurons that failed to establish appropriate connections, with which it partially overlaps.

D

Formation of synaptic connections takes place immediately after neural progenitors exit the cell cycle, with which it partially overlaps.
