Inside every adolescent brain, 86 billion neurons connect and collide to produce the most frustrating, chaotic and exhilarating changes that will ever happen to us. Brainstorm is a unique theatrical investigation into how teenagers' brains work, and why they're designed by evolution to be the way they are. Created by Ned Glasier and Emily Lim with Company Three (formerly Islington Community Theatre), in collaboration with neuroscientists Professor Sarah-Jayne Blakemore and Dr Kate Mills, the play is designed to be created and performed by a company of teenagers, drawing directly on their personal experiences. This edition contains a series of exercises, resources and activities to help schools, youth-theatre groups and young companies create and perform their own Brainstorm. It also features the complete script of the original production which played at Park Theatre and the National Theatre, London, in 2015.
