When you think of something, anything, your brain needs to interpret if that is something that really happen, or if it’s something that you imagined. For example, if I were to ask you, did you really tie your shoes this morning, or did you imagine that you did? If you can answer me positively whether or not you did, then you have an extra fold in your brain that helps you distinguish between reality and imagination.
This extra fold is located in the front area of the brain, it’s called the paracingulate sulcus, PCS for short, it can help people remember whether they did something or they imagined something. This area is actually one of the final structural folds to develop before birth, the size of this fold varies greatly between small, medium, large, or none at all. People that actually have this fold, remember things better than people who didn’t.
This discovery can help us understand some mental disorders like schizophrenia, Alzheimer’s, and many others. But according to Jon SImons of Cambridge Experimental Psychology department and Behavioral and Clinical Neuroscience Institute: They don’t know how this research is going to help them cure patients, because the fold happens so shortly before birth, it’s not something that can be physically changed.
But that’s beyond the problem, the fact of the matter is that they have finally found something that can help them understand how the human mind works a little better. What if every single fold of our brain had a similar purpose?
