Why Songs Get Stuck in Your Head
Your brain does not replay the whole recording. It reconstructs a compact loop that is easy to cue and difficult to complete.

What Causes Déjà Vu
The moment feels remembered, but no memory arrives. Déjà vu may be the brain noticing that mismatch in real time.

Why You See Faces in Things
Two dark marks above a line can be enough. A visual system tuned for faces would rather make a fast false alarm than miss one.

What this hub covers
Experience is built across brain and body.
Brain & Mind explores the systems behind memory, social attention, aesthetic emotion and sensory completion. The stories stay close to observable mechanisms: nerve pathways, imaging findings, physiological measurements and experiments that reveal where explanations are still incomplete.
The goal is not to reduce a memory or a piece of music to one brain region. It is to show how distributed networks, learned expectations and body responses meet—and why individual experience can still vary inside shared biology.
