Flashcards
0/6
Neurogenesis
Formation of new neurons typically during embryonic development; timeframe: starts at 3 weeks post-conception and peaks at mid-gestation.
Cell Migration
Movement of neurons to their final destinations in the nervous system; timeframe: mainly from 3 to 5 months gestation.
Differentiation
Process where neurons begin to take on specific roles; timeframe: starts around 5 months gestation, continues after birth.
Synaptogenesis
Formation of synapses between neurons; timeframe: begins prenatally and continues intensely during the first few years of life, but is an ongoing process throughout the lifespan.
Neuronal Cell Death (Apoptosis)
Programmed cell death of neurons; timeframe: Peaks during the prenatal period but continues through early development.
Myelination
Process of forming a myelin sheath around neurons to increase the speed of impulse conduction; timeframe: begins late in gestation and continues into early adulthood.
