Your brain is about 1.4 kilograms of tissue with roughly 86 billion neurons, and it is the least understood organ in the body. We cover how neurons actually communicate, what the major regions do, why the left brain versus right brain idea is a myth, and why consciousness remains genuinely unexplained.

You'll come away understanding what neuroplasticity really means, why brain scans are more ambiguous than headlines suggest, and which popular brain facts are simply false.
