The Noradrenaline meme typically utilizes diagrams of brain chemistry or hyper-stylized depictions of neurological arousal to represent moments of extreme focus, stress, or sudden realization. While often rooted in scientific educational graphics, the internet repurposed the term to symbolize the 'fight-or-flight' response during high-stakes situations like cramming for exams or gaming clutches. It gained traction within student and science communities on platforms like Reddit and Twitter, evolving into a relatable shorthand for that specific brand of panicked productivity where the body's natural chemistry takes over to finish a task at the last possible second.
