Hebbian Theory: Neurons That Fire Together, Wire Together

Donald Hebb · 1949

"Learning is physical — repeated co-activation between neurons strengthens the connection between them, which is how experience becomes structure."

The idea

Hebb's 1949 rule is the closest thing neuroscience has to a founding law: neurons that fire together, wire together. Every habit, skill, and memory is this rule running on repeat.

Why it works

The takeaway — recall it first

Neuroplasticity: The Brain That Changes Itself

"The brain physically rewires itself in response to repeated thought and behavior throughout adulthood, not just childhood — meaning habits, skills, and even chronic thought patterns are more changeable at a neural level than 'fixed personality' framing suggests."
