Nowadays with so many Baby Boomers in America, there are infomercials on nutrition for the brain that helps to create new neurons for the brain in an effort to stem the onset of dementia or Alzheimer's. So, the idea that one can regenerate neurons--"neurons form new synapses"--in the brain agrees with the video on which the narrator discusses "Neural Plasticity." After all, it follows the concept that all moving parts of the human body need exercise to keep them functioning at optimum level. 

Further, the concept of "synaptic pruning" as the "willowing down of things already learned" brings to the foreground the idea of reawakening these memories through life-long learning. So, if one has played the piano in his/her youth, re-taking piano lessons can reawaken the brain, "beefing up neurons," Indeed, there can be no question that people should be lifelong learners, exercising their brains along with their bodies.

The brain is not plastic in a literal sense. It is however, forever evolving and changing as we grow up. It doesn't stop at a certain period of our lives. Neuroplasticity was mentioned in the video and it simply means that the neurons of our brains continuously change as we learn new things and acquire information. The brain undergoes different processes at different stages of our lives. It allows us mo learn the basics, memorize what we learn in school and recall things we might have forgotten. Synaptic pruning was also mentioned in the video and it is further explained here
