text: Yo, nerve agents, they ain't no joke
  In conflicts or attacks, they make you choke
  If you don't get treated, it's a dangerous game
  Brain damage and behavior, it won't be the same
  
  But hold up, there's some hope in sight
  In vivo cell therapy, it's shining bright
  A way to repair the brain in a delayed fashion
  Using neural progenitors, that's the main attraction
  
  These cells would mobilize, make their move
  Engraft in the damaged regions, they groove
  Transforming into neurons, functional and true
  This review breaks it down, giving you the clue
  
  We'll talk about nerve agent poisoning, don't you miss
  And emergency treatment, gotta act quick, no diss
  Then we'll dive into cell therapy, that's the key
  And how it can heal those brain lesions, you see
