How Your Brain Works: Neuroscience to Fall Asleep To

How does your brain actually work? In this in-depth neuroscience video, we explore the truth behind how your brain powers your thoughts, memories, emotions, sleep, and learning. You’ll discover why your brain consumes 20% of your body’s energy, how 86 billion neurons communicate through electrical and chemical signals, and why modern science says we do not just use 10% of our brain.
​
We break down how memory really works, why the brain’s storage capacity is estimated around 1 petabyte, and how recalling a memory can actually make it temporarily vulnerable to change. You’ll learn about London taxi drivers’ enlarged hippocampi, the role of sleep and the glymphatic system in “cleaning” the brain, and why forgetting is now seen as a feature of a healthy mind, not a flaw.
​
This video also explains neuroplasticity—your brain’s lifelong ability to rewire itself—showing how new neural pathways form as you learn, recover from injury, or change habits. We’ll cover recent breakthroughs (2024–2025) in brain research: fruit fly connectomes, blood vessel waves in the cortex, gene therapy advances, and a potential rejuvenation factor for aging brains.
​
Along the way, we debunk common brain myths (10% myth, brain size = intelligence, “left-brained vs right-brained”), explore why teenage brains are wired for risk, and look at the ten greatest unsolved mysteries of the brain—including consciousness, time perception, and why we dream.

If you’re interested in how your brain really works, how to optimize it with sleep and learning, and what neuroscience is discovering about who we are, this video is for you.
