Evidence for adult neurogenesis in non-neurogenic niches in non-traditional animals likely attributed to sociosexual adaptations.
| Species | Region | Notes |
|---|---|---|
| African cichlid fish (Astatotilapia burtoni) | Central posterior thalamic nucleus; nucleus of the lateral recess; preoptic area; periventricular nucleus of the posterior tuberculum; ventral nucleus of the ventral telencephalon | Increased cell proliferation in socially-dominant males (Muraska et al., 2012) |
| Golden hamster | Posterior medial amygdala | Testosterone increases cell proliferation, but not cell survival (Antzoulatos et al., 2008) |
| Green treefrog (Hyla cinerea) | Pre-optic area (male only), infundibular hypothalamus | Acoustic stimuli (mating chorus) increased cell proliferation (Almli and Wilczynski, 2012) |
| Iberian wall lizard (Podarcis hispanica) | Main and accessory olfactory bulbs, lateral cortex, nucleus sphericus | Males demonstrated increased cell proliferation and enhanced responsiveness to social chemical stimuli (Sampedro et al., 2008) |
| Meadow vole | Posterior cortical and posterior medial nuclei of amygdala | Estradiol treatment increases cell proliferation as compared to prairie voles (Fowler et al., 2005) |
| Prairie vole | Amygdala, hypothalamus | Male-exposure increases cell proliferation as compared to isolation (Fowler et al., 2002) |
| Red-sided garter snake (Thanophis sirtalis parietalis) | Septal nucleus, nucleus sphericus, pre-optic area, hypothalamus | Increased cell proliferation during the fall (Maine et al., 2014) |
| Ring dove | Pre-optic area | GnRH neuron regeneration in response to electrolytic damage (Cheng et al., 2011) |
| Soay sheep | Thalamus, hypothalamus (including median eminence, tanycyte projection zone) | Short photoperiod increases cell proliferation (Migaud et al., 2011; Hazlerigg et al., 2013) |
| Zebra finch (Taeniopygia guttata) | High vocal center, neostriatum caudale, Area X | Large group pairing increases new cell survival (Lipkind et al., 2002) |
| Zebrafish (Danio rerio) | Ventral telencephalon, diencephalic periventricular pre-optic area, dorsal hypothalamic nuclei | Estradiol treatments decreases cell proliferation (Makantasi and Dermon, 2014) |
This is not an exhaustive list; rather, it demonstrates the diversity of species and regions in which evidence for adult-generated neurons exists.
