text: Yo, there's mad debates 'bout retrograde amnesia (RA) base,
  Some say memories chill in a temporal space,
  In the hippocampal complex, holdin' it tight,
  Before gettin' "consolidated," reorganized, that's right.
  
  Others say the medial temporal lobes stay in the mix,
  Storage and retrieval, autobiographical memory's fix,
  Multiple trace theory, that's the alternate view,
  The present study used MRI, seekin' what's true.
  
  Forty patients with pathologies and volume loss,
  Different sites affected, causin' memory toss,
  Three measures of RA, correlated with the brain,
  Autobiographical and remote memories, the main.
  
  Widespread neural networks play a major role,
  Storing and retrievin', keepin' memories whole,
  Brain volume measures got the stats to show,
  60% of the variance, yo, that's how they flow.
  
  Diencephalic patients, memories held tight,
  Incidents and facts, their autobiographical might,
  Frontal lesions in others, 60-68% in their case,
  Volume matters, impactin' memory space.
  
  Medial temporal lobe volume, the diencephalic crew,
  Thalamic changes, correlations that grew,
  But not in herpes encephalitis or hypoxia's wake,
  Temporal lobes implicated, a different take.
  
  Multiple trace theory, it takes a hit,
  As the findings reveal, not quite legit.
