text: Extrastriate visual areas, they be feelin' the vibe,
  Activated by image symmetry, it's a real high,
  But at the object-level, it's a mystery untold,
  So we delved into it, let the truth unfold.
  
  Electrophysiological responses we did explore,
  Symmetry generated, shapes partially occluded for sure,
  We ran four experiments, a hundred and twelve in sight,
  Using a similar paradigm, we kept it tight.
  
  Abstract shapes, symmetric or asymmetric, we displayed,
  For 250 milliseconds, they were fully portrayed,
  Then a big rectangle covered 'em, took 'em away,
  For another 250 milliseconds, a brief delay.
  
  Moved to the side, revealed what was hidden behind,
  For a thousand milliseconds, the occlusion declined,
  But at that point, no symmetry could be seen,
  Retinal image information, it was clean.
  
  In some trials, the shape remained the same,
  In others, a novel one came into the game,
  Participants matched similarity or color,
  Or the orientation of a triangle, no duller.
  
  From t0 to t1, the shapes in plain view,
  Automatic symmetry-specific responses, they drew,
  All experiments showed this ERP reaction,
  To the fully-visible shapes, a symmetrical attraction.
  
  Crucially, there was a response to the occluded,
  Shapes recognized as seen before, they concluded,
  Exp. 2 and Exp. 4 confirmed this find,
  No carry-over response, it left no bind.
  
  In the extrastriate symmetry-network we trust,
  Amodal representation of symmetry, it's a must,
  Even from occluded objects, previously whole,
  The power of symmetry, it takes a toll.
