Being fooled by optical illusions might mean you’re more self-aware

But bigger is not necessarily better in terms of brain power. It might be better to have fewer synaptic connections for more focused and coherent decision making. A brain with more visual volume and less frontal volume might actually work better."



Not everyone reacts to optical illusions equally: some are completely fooled by them, while others just can't see what all the fuss is about. It depends on the size of your visual cortex...and that can determine how introspective you are. Specifically, the amount of gray matter in the visual cortex goes a long way to determining how much a person is able to process and solve optical illusions, a fact that was discovered last year by researchers at University College London. They then decided to take things a step further by looking for other parts of the brain that correlate with the size of the visual cortex.
