GIRL,S BRAIN MATURE FASTER THAN BOYS' BRAIN

It's    always  been  conventional  wisdom    that  girls    reach  maturity    more  quickly  than  boys,but  now  scientists    have  provided  some  proof .
In  a  new  research  ,an  international  group   of  researchers    led  by  a  team  from  Newcastle    University  in  England   found that     girls'   brain  march   through    the  reorganization   and  pruning  typical  of   normal  brain  development  earlier  than  boys'  brains.In  the  study  ,in  which   120  people  between  the  age  of   4  to  40   were  scanned    using  MRI's ,the  scientists  documented   the  ebb     and  flow  of  new    neural  connections ,and  found   that  some  brain  fibers   that  bridged  far  flung  regions   of  the  brain  tended  to  remain stable ,  while  shorter  connections ,  many  of  which   are  redundant ,  were  edited  away.And  the  entire  reorganization  seemed  to  occur   sooner  in  girls   than  in  boys'  brain. 
Girls  also  tended  to  have    more  connections  across  the   two   hemispheres  of  the  brain.The  researchers   believe  that  the   earlier  reorganization  in  the  girls   make  the  brain  work   more  efficiently,  and  therefore    reach  a  more  mature   state  for    processing  the  environment. What  drives  the  gender - based .in  timing     isn't  clear    from  the  current  study ,  but  the  results  suggest   that   may  be   a  question  worth  investigating .
