text: Yo, check it out, we got goats in the house
  Investigatin' analgesic neural circuits, no doubt
  Electroacupuncture, different acupoints in the brain
  Baihui-Santai or Housanli, causin' some pain
  
  Stimulated for 30 minutes, that's the time
  Measurin' pain threshold, potassium iontophoresis, it's prime
  Levels of c-Fos, Streptavidin-Biotin Complex doin' the test
  Immunohistochemistry, we ain't takin' no rest
  
  Results showed the pain threshold, let me break it down
  EA at Baihui-Santai, higher by 44.74% around
  EA at Housanli, lower at 32.64% they found
  Compared to blank control, c-Fos expression, it's profound
  
  Medial septal nucleus, ARC, and AB in the mix
  Lateral habenula nucleus, vlPAG, yo, that's the fix
  Locus coeruleus, NRM, pituitary gland too
  Spinal cord dorsal horn, they all got their due
  
  EA at Baihui-Santai, AB got an increase
  But MSN, paraventricular nucleus, they decreased
  HL and SDH, they felt the change
  Common pathways activated, yo, it's not strange
  
  ARC-PAG-NRM/LC-SDH, they all play their part
  Hypothalamus-pituitary, it's a neural pathway chart
  EA-induced analgesia, acupoints got the game
  Two sets in the mix, they ain't the same
