Stim Cells: Understanding the Rhythms of Neurodivergence

Stim Cells: Understanding the Rhythms of Neurodivergence
By Ptim Pellerin

Some people walk through the world in a straight line. Others flap, bounce, echo, rock, or hum their way through.

This book is for the second kind.

Stim Cells is a groundbreaking and deeply personal exploration of the rich, rhythmic world of stimming — the self-regulatory behaviors that help neurodivergent people survive, thrive, and connect. Through science, storytelling, and lived experience, Ptim Pellerin reframes stimming not as a symptom to suppress, but as a language of the body and brain.

Whether you stim or love someone who does, this book will change the way you understand movement, emotion, attention, and identity.

It’s not a quirk. It’s a signal. It’s not wrong. It’s wisdom.

“In the rhythm of our bodies, we remember who we are.”
