text: Yo, check it out, brain activity, recognition of action,
  Differs between subjects, it's causing a distraction.
  Genetic and environment, they play a role,
  But how much they affect, we don't fully know.
  
  We used MEG signals, twins were our test,
  To evaluate the factors, put them to the test.
  Twenty pairs of monozygotic, eleven dizygotic,
  Watched finger movements, yeah, they got hypnotic.
  
  Beamformer and stats, we analyzed the data,
  Looking for differences, cortical activity, yeah.
  Event-related desynchronisation in the β band,
  Left inferior parietal lobule, that's where it lands.
  
  Observation and execution, both showed the same,
  Significant ERD, it was the name of the game.
  And when it comes to twins, we found something cool,
  Monozygotic pairs, stronger correlation rule.
  
  Compared to unrelated, the bond was tight,
  Z-test proved it, came out just right.
  Heritability of β-band ERD at the IPL,
  In an ACE model, it was 67%, can you tell?
  
  So, the conclusion is clear, it's genetics in play,
  Environmental factors, they don't have much to say.
  Action recognition, cortical activity's location,
  And the frequency characteristics, shape the situation.
