text: Yo, check it out, this study went all out,
  Investigated genistein's effects, no doubt.
  Perinatal exposure, rats were chosen,
  To see how it affected their central nervous system.
  
  Pregnant dams were given GEN, hear the plan,
  1 or 10 mg/kg/day, that was the span.
  Oral intake from day ten 'til postnatal fourteen,
  To see if GEN would make their offspring keen.
  
  Behavioral tests were conducted, let me explain,
  Open-field, elevated plus-maze, all part of the game.
  The MAZE test, an appetite-motivation quest,
  Used to measure spatial learning, that's the best.
  
  In the MAZE test, GEN groups showed a feat,
  Shorter latency from start to goal, can't be beat.
  Both sexes, they outperformed the vehicle crew,
  GEN had an impact, that's the clue.
  
  But in the passive avoidance test, a different story,
  GEN's effect wasn't straightforward, it got gory.
  Both sexes saw inhibition, non-monotonically,
  Females in the low dose group, it hit significantly.
  
  Now let's talk locomotor activity and emotionality,
  Open-field and elevated-plus maze, the reality.
  Perinatal GEN exposure didn't cause much strife,
  No significant changes, it didn't alter their life.
  
  To sum it up, GEN exposure had its way,
  Improved spatial learning, that's what they say.
  But when it came to passive avoidance, it wasn't cool,
  GEN messed with their memory, that's the rule.
