In Sync explores whether women living together might exhibit shared patterns of brain activity when their menstrual cycles align. While menstrual synchrony has long been debated - and often dismissed - in anthropology and biology, no one has asked whether synchrony could emerge at the level of neural rhythms. Drawing on research showing that people’s brainwaves can fall into rhythm during conversation, music, or shared attention, this project asks a provocative question: could hormonal cycles act as subtle conductors, shaping collective states of mind among women?

The study follows small groups of roommates over several months, combining portable EEG, cycle tracking, and shared‑activity sessions such as conversation, co‑presence, and collaborative art. Rather than seeking to “prove” synchrony, the project takes an exploratory, curiosity‑driven approach - looking for subtle harmonies that may arise when biological rhythms overlap. Scientific data will be paired with artistic translation, transforming brainwave patterns and hormonal fluctuations into visual installations that make invisible forms of connection perceptible.

At its core, In Sync challenges the assumption that the brain is an isolated organ. If neural synchrony linked to menstrual cycles exists, it suggests that women’s health may carry collective signatures; if it does not, the inquiry still reframes cycles as phenomena worthy of scientific and cultural attention. The project ultimately aims to reimagine women’s biology not as private or stigmatized, but as a potential site of resonance, creativity, and shared human experience
