In fact, the brain is a 3 and intricate organ that is constantly active. 4 signals in the brain are responsible for all of our thoughts, emotions, and movements. The 5 held belief that certain areas of the brain correspond to specific functions, such as language and memory, has been 6 debunked. The brain is much more 7 than that. Neuroscientists have 8 that the brain is capable of 9 with itself and rewire its connections in response to new experiences. This is known as neuroplasticity. This is why learning new skills and forming new habits can be so difficult at first but then becomes easier with practice. The brain has a 10 to change and adapt, but it also has its limits.
