WEBVTT 00:00:03.760 --> 00:00:09.600 not so long ago, many scientists believed that the brain did not change after childhood 00:00:09.600 --> 00:00:14.060 that it was hard-wired, and fixed by the time we became adults 00:00:14.100 --> 00:00:19.800 but recent advances in only the last decade now tell us that this is simply not true 00:00:19.800 --> 00:00:25.800 the brain can, and does change throughout our lives: it is adaptable, like plastic 00:00:25.800 --> 00:00:29.940 hence neuroscientists call this 'neuroplasticity' 00:00:29.940 --> 00:00:33.040 how does neuroplasticity work? 00:00:33.040 --> 00:00:36.940 if you think of your brain as a dynamic, connected power grid 00:00:36.940 --> 00:00:44.220 there are billions of pathways, or roads, lighting up every time you think, feel or do something 00:00:44.220 --> 00:00:51.560 some of these roads are well travelled: these are our habits, our established ways of thinking, feeling and doing 00:00:51.560 --> 00:00:59.660 every time we think in a certain way, practice a particular task or feel a specific emotion, we strengthen this road 00:00:59.660 --> 00:01:04.480 it becomes easier for our brains to travel this pathway 00:01:04.480 --> 00:01:09.820 say we think about something differently, learn a new task, or choose a different emotion 00:01:09.820 --> 00:01:13.860 we start carving out a new road - if we keep travelling that road 00:01:13.860 --> 00:01:21.920 our brains begin to use this pathway more, and this new way of thinking, feeling, or doing becomes second nature 00:01:21.920 --> 00:01:26.300 the old pathway gets used less and less and weakens 00:01:26.300 --> 00:01:34.140 this process of rewiring your brain by forming new connections and weakening old ones is neuroplasticity in action 00:01:34.140 --> 00:01:40.280 the good news is that we all have the ability to learn and change, by rewiring our brains 00:01:40.280 --> 00:01:44.380 if you have ever changed a bad habit, or thought about something differently 00:01:44.380 --> 00:01:50.340 you have carved a new pathway in your brain and experienced neuroplasticity firsthand 00:01:50.340 --> 00:01:53.840 with repeated and directed attention towards your desired change 00:01:53.840 --> 00:01:57.440 you can rewire your brain
