=====Neurogenic region (NR)=====

New neurons are continually born throughout adulthood predominantly in several regions of the brain:

The [[subventricular zone]] (SVZ) 

[[Striatal interneuron]]s

The subgranular zone (SGZ), part of the [[dentate gyrus]] of [[hippocampus]].

The [[nucleus accumbens]], specifically medium spiny neurons

[[Glioblastoma]] GBM contrast-enhancing recurrence is significantly associated with proximity to NRs. NR-contacting initial tumors were more likely to recur out of radiation treatment fields
