This podcast episode discusses 10 myths about the brain, including the misconception that the brain is only gray.
03:36
The brain contains both gray matter and white matter, with the substantia nigra being a black region that is important for motor control and may be related to Parkinson's disease.
07:05
Listening to classical music won't make you smarter, but learning to play music can improve concentration, self-confidence, and coordination; humans don't have the biggest brains, whales do, but the size of the brain relative to the rest of the body is what matters.
10:36
Humans have the largest cerebral cortex, which is where higher functions are carried out, and that's what separates us from other mammals.
14:07
Brain damage is not always permanent because the brain is extremely resilient and can rewire itself through plasticity, allowing for new neural connections and the ability to relearn lost abilities.
17:37
The idea that humans only use 10 percent of their brain is a myth, and while all regions of the brain are being used, there is a theory that savantism is the result of the brain's frontal lobe prioritizing certain functions over others.
20:59
Long-term drug use may cause certain structures in the brain to grow, leading to addiction, while alcohol does not kill brain cells but damages the dendrites that allow neurons to communicate with each other.
