text: Yo, check it out, listen up real quick,
  I'm 'bout to drop some knowledge, so let's get specific.
  Neuromyelitis optica, known as NMO,
  It's a disease that brings the pain, you gotta know.
  
  Optic neuritis and transverse myelitis, that's the deal,
  Severe relapses, it's a tough road to heal.
  And let me tell you, it's got a female predilection,
  Stronger in the ladies, that's the connection.
  
  Pain is a common symptom, it's hard to ignore,
  But not enough studies, we need to explore.
  Using MRI techniques, we took a look,
  At NMO patients and the pain they took.
  
  Thirty-eight females with NMO in the mix,
  Twenty-eight with pain, ten without, no tricks.
  We used the Brief Pain Inventory to classify,
  And recruited healthy females, let me clarify.
  
  With the FSL Image Registration and Segmentation Toolbox,
  We measured subcortical volumes, it rocks!
  Voxel-based morphometry analyzed gray matter,
  To see the brain's morphology, it's a data scatter.
  
  And we also checked the correlation, you see,
  Between structural measurements and clinical indices, gee!
  The results came in, let me break it down,
  So you can understand the knowledge we found.
  
  No differences in cortical GM density, that's a fact,
  Between the NMOWP and NMOWoP pack.
  But the NMOWP group had smaller volumes, no joke,
  In the hippocampus and pallidum, that's the stroke.
  
  And a negative correlation we did find,
  Between BPI and accumbens nucleus, oh my!
  Also with the thalamus, there's a connection,
  For NMO patients with pain, it's a reflection.
  
  So now we know, there's structural abnormality,
  In NMO female patients with pain, the reality.
  It's a breakthrough for our understanding, no doubt,
  Of the brain's morphology, what it's all about.
