Am I an Introvert, Extrovert, or Ambivert?
Introvert, extrovert, or somewhere in between? It comes down to what drains you and what recharges you. Here is how to place yourself on the spectrum.
What Is the Connectome? A Map of the Brain's Wiring
Your brain is defined less by its parts than by how they connect. The connectome is the map of that wiring, and building it is one of neuroscience's biggest projects.
How Scientists Map the Brain
Brain maps do not come from one tool but from many, each revealing a different layer. Here is how neuroscientists chart the brain's regions and its wiring.
The Neuroscience of Introversion and Extraversion
From a lemon juice experiment in the 1960s to modern dopamine research, here is what neuroscience actually shows, and does not show, about introverts and extraverts.
What Primate Brains Reveal About the Human Mind
