text: Yo, check it out, here's the deal
  I'm 'bout to drop some knowledge, gotta keep it real
  In rodents, most GABAergic interneurons in the brain
  They come alive during embryonic development, it's insane
  They're born in the ganglionic eminences, that's the GE
  Then they migrate to the cortical plate, can't you see?
  
  But hold up, there's a subset that's different, listen closely
  They keep on being generated postnatally, you know, mostly
  In the subventricular zone, that's the SVZ
  These interneurons find their way to the olfactory bulb, OB
  
  They take a journey through the rostral migratory stream, RMS
  In transgenic mice with EGFP, we witness the progress
  Those 5-HT(3)-positive neurons, they shine bright
  Revealing more pathways in the early postnatal brain, alright!
  
  Through time-lapse imaging, we see the migration unfold
  EGFP-positive cells moving, they're bold
  From the SVZ, they venture to different brain parts
  Cortex, striatum, and even the nucleus accumbens, chart-toppers on the charts
  
  To confirm their destiny, we look at doublecortin, DCX
  Expression tells us they're on the right flex
  Using BrdU and retrovirus-based tricks
  We find evidence that these neuroblasts were born postnatally, no fix
  
  And guess what? They develop a GABAergic vibe
  These migratory cells, they surely thrive
  So, let's give props to the SVZ, it's a real treasure
  A reservoir of GABAergic interneurons, bringing us pleasure
  Not just for the olfactory bulb, but also for the cortex and subcortical domains
  This rap's a wrap, hope you enjoyed these brainy refrains!
