text: Yo, listen up, 'cause I'm 'bout to drop some knowledge,
  The brain stays busy, gettin' hit with stimuli barrage,
  Determinin' what grabs attention, it's all about the salience,
  A brain system called the 'salience network' with brilliance.
  
  Key nodes in the insular cortices, they hold the power,
  Detectin' what's important, every second, every hour,
  Coordinatin' resources, makin' connections strong,
  This network's vital, it's where the action belongs.
  
  New evidence is showin', things ain't always right,
  In neuropsychiatric disorders, the insula takes flight,
  Engagement's atypical, subdivisions outta sync,
  Salience network affected, gotta find a link.
