abstract = {In many vertebrates, postnatally generated neurons often
migrate long distances to reach their final destination,
where they help shape local circuit activity. Concerted
action of extrinsic stimuli is required to regulate
long-distance migration. Some migratory principles are
evolutionarily conserved, whereas others are species and
cell type specific. Here we identified a serotonergic
mechanism that governs migration of postnatally generated
neurons in the mouse brain. Serotonergic axons originating
from the raphe nuclei exhibit a conspicuous alignment with
subventricular zone-derived neuroblasts. Optogenetic axonal
activation provides functional evidence for serotonergic
modulation of neuroblast migration. Furthermore, we show
that the underlying mechanism involves serotonin receptor 3A
(5HT3A)-mediated calcium influx. Thus, 5HT3A receptor
deletion in neuroblasts impaired speed and directionality of
migration and abolished calcium spikes. We speculate that
serotonergic modulation of postnatally generated neuroblast
migration is evolutionarily conserved as indicated by the
presence of serotonergic axons in migratory paths in other
vertebrates.},
