Temporally and spatially organized cell fate transitions are at the basis of the genesis of multicellular organisms and alterations from this body plan can generate pathologies. One such process is neurogenesis, a highly complex event implicating a variety of regulatory signals, which in a multicellular organization context (80-90 billions of neurons interconnected by several trillions of interconnections) gives rise to one of the most complex organs retrieved in higher organisms: the brain.
