Organs tend to be relatively predictable. Take the heart, which beats faster when we’re scared and slows down when we’re relaxed. But the brain is a mysterious beast. With as many neurons as there are stars in a mid-sized galaxy, scientific understanding of our grey matter is like our knowledge of space: limited by the near-infinite pathways and possibilities.
It’s also difficult to know when our brain’s blips are perfectly normal or a sign of deterioration. Keep walking into rooms and forgetting why you’re there? You may be experiencing the commonly occurring “doorway effect”, where our brains compartmentalise information. Or, it could be a symptom of Alzheimer’s.
