Summary
The fattiest organ in the body. Omega-3 deficiency can cause memory and learning problems.
The person whose lie ‘shows on their face’ often can’t hide emotion. ‘Better’ lying usually means better emotion control and a more consistent story. It’s not words—it’s signals.
Recognizing someone but blanking on their name isn’t laziness: the brain encodes faces as rich visual identity files, while names stay as fragile labels. So the face pops up, the name doesn’t.
Snacking more when you’re sleep-deprived isn’t just weak willpower—it can be biology. With less sleep, appetite signals can shift and the brain chases quick rewards. The fridge call is nightly.
Yawns can be contagious for a reason: the brain can ‘simulate’ what it sees. The mirror neuron idea links empathy and learning in a single mechanism.
The mind doesn’t compute everything from scratch; it uses shortcuts. They’re fast but can be trapped: a trustworthy-looking face or familiar phrasing creates a ‘true’ feeling. Speed trades off with accuracy.
Recalling a memory isn’t pulling it off a shelf—it’s rewriting it. Each recall can update details, so the scene you’re sure about may be the latest edit.
