MEANS REARRANGING THE WAY OUR BRAIN WORKS.

OUR BRAIN HAS AN ASTONISHING 100 BILLION NEURONS,

OR BRAIN CELLS, ALL CONNECTED TOGETHER.

LEARNING IS ABOUT CREATING AND STRENGTHENING PATHWAYS

THROUGH THESE NEURONS FOR IMPULSES OF ELECTRICITY.

BUT BETWEEN EACH AND EVERY CONNECTION IN OUR BRAINS,

THERE'S A TINY GAP CALLED A SYNAPSE.

FOR ANY OF US TO LEARN SOMETHING NEW,

THE ELECTRICAL SIGNAL HAS TO JUMP ACROSS THIS GAP

TO CONTINUE ITS JOURNEY.

THE GAP BETWEEN THE TWO BRAIN CELLS IS TINY.

BUT THAT DOESN'T MEAN IT'S STRAIGHTFORWARD

FOR A SIGNAL TO GET FROM ONE SIDE TO THE OTHER.

FOR US, IT'S LIKE CROSSING A DEEP RAVINE.

AND GETTING FROM ONE SIDE TO THE OTHER

SHOULD TELL US SOMETHING ABOUT THE WAY WE LEARN.

THE FIRST TIME A SIGNAL CROSSES FROM ONE BRAIN CELL TO THE OTHER

DEMANDS THE MOST EFFORT.

AND IT'S THE SAME WHEN WE CROSS OUR RAVINE.

THE FIRST TRIP ACROSS IT IS THE HARDEST.

HAVING CROSSED THE RAVINE ONCE,

THE JOURNEYS ACROSS GET EASIER AND EASIER.

AND A SIMILAR THING HAPPENS WHEN WE LEARN SOMETHING.

TO START WITH, LEARNING IS DIFFICULT.

BUT AS THE SIGNAL CROSSES THE GAP

BETWEEN THE BRAIN CELLS AGAIN AND AGAIN,

WE ESTABLISH A MORE SOLID PATHWAY.

SORRY ABOUT THAT.

BY THE TIME WE'VE MADE THE CROSSING

OVER AND OVER AGAIN, IT BECOMES EFFORTLESS.

WE CAN DO IT WHENEVER WE LIKE.

WE FINALLY LEARNED SOMETHING. \r�
