Table 1 Timing of cerebellar afferent fiber arrival in different species during the embryonic period

From: Embryonic stages in cerebellar afferent development

Afferent fiber Mouse Rat Chicken Xenopus Reptile Fisha
Spinocerebellar a E13/14 E15 HH33/E7 Stage 50 n/a Stage 32
Trigeminocerebellar a n/a E22/P0 n/a Stage 48 n/a Stage 32
Vestibulocerebellar a E11-13 13-14/15 n/a Stage 48 n/a n/a
Reticulocerebellar a E13/14 E16/17 n/a Stage 48 n/a Stage 32
Pontocerebellar a E16 perinatal n/a n/a n/a n/a
Olivocerebellar a E14/15 E17 E9 n/a n/a Stage 32
Serotonergic cerebellar a postnatal postnatal n/a Stage 56 n/a n/a
Noadrenergic cerebellar a E14 E17 n/a n/a n/a n/a
Cholinergic cerebellar a n/a n/a n/a n/a n/a n/a
Dopaminergic cerebellar a n/a n/a n/a n/a n/a n/a
Histaminergic cerebellar a n/a n/a n/a n/a n/a n/a
  1. Note: a, afferent fiber
  2. The “n/a” means that there is no data available for afferents projection to the cerebellum during embryonic development in these species
  3. aThis is the only stage that has been studied; therefore everything arrives at stage 32
