Neurons that fire together, wire together

A note for Lesson no. 3, "Little Brains Wire Themselves to Their World," in Seven and a Half Lessons About the Brain by Lisa Feldman Barrett.
Some context from page 51 is:

As neuroscientists like to say, “Neurons that fire together, wire together.”

The appendix adds:

...the phenomenon is more formally known as Hebb’s principle or Hebbian plasticity.

The original reference for this appendix entry is Hebb (1949).[1]
