A practical guide to what meditation research can and can’t measure—EEG, fMRI, HRV, and behavioral tests—plus steps to track your own practice without turning correlations into metaphysical proof.

A grounded guide to quantum-consciousness proposals—what mechanisms they actually propose, the strongest objections, and how to turn big claims into testable bets without confusing interpretation for evidence.

A Mount Sinai–linked report argues that TIMP2, a “youth-associated” protein, can shift aged microglia away from inflammatory states and restore debris-clearing function in mice. Here’s what the source claims, what’s established vs still uncertain, and why this matters for brain aging—and for how we think about mind and biology without overreaching.

Neural correlates of consciousness (NCCs) help researchers link subjective experience to measurable brain activity—but correlation isn’t the same as explanation. This beginner-friendly guide shows what we can measure, how to evaluate NCC claims, common pitfalls, and what remains genuinely unresolved.
