Winner Effect

In her report, Hailan Hu proposed that through optogenetic experiments, it can be
determined that the prefrontal cortex controls the competition-related behaviors of
animals. Activating the prefrontal cortex with light does not change muscle strength.
The victory of animals comes more from their courage to embrace change, confidence
and other factors. Hailan Hu concluded that in social competition, personality traits
determined by the cerebral cortex can overcome physical weakness and give animals
an advantageous position; acquired experience can make animals with congenital
weakness gain an advantageous position by reshaping the neural circuit of their brain;
the Winner Effect (victorious experience could increase the probability of winning in
the next time) can be migrated and generalized in different forms of competition to
consolidate the dominant position.
