Over the course of a person's life, the brain constantly optimizes and reassembles its cranial nerves connections, pruning redundant connections so that useful connections can be made more quickly  The researchers selected 121 healthy volunteers aged 4-20 years old and used the touch resonance technology to analyze the changes in the neural connections of this age group as the brain develops and matures The results showed that the pruning time of female was earlier than that of male
The pruning and reorganization of the brain has resulted in a significant increase in the efficiency of various cognitive activities.
 The researchers therefore believe that the female brain is more efficient than the male brain
