You may find this primer about brain development and functioning, created by the Society of Neuroscience, quite interesting. This is a nonprofit organization of scientists and physicians whose mission it is to research and educate. The primer is called Brain Facts. It's written with a non-medical audience in mind and it's available for free. Definitely worth checking out if you have an interest in how the brain works, how memory is stored in the brain, how changes in the neural pathways effect our memory, the process of learning, and more.
