In The Pussification of Biotech: Period Brain, menstrual blood is reclaimed as both origin and operator of knowledge production. This film captures the live cellular unfolding of primary tissue explanted directly from a menstrual cup and cultured in N2B27 medium with murine FGF and EGF for 44 hours. Under 40x magnification, time-lapse microscopy reveals the emergence of dendritic protrusions—evidence of early neuronal differentiation—rendering the so-called “period brain” not as myth, but as material intelligence. Produced during an artist research residency at Cultivamos Cultura (PT) in partnership with the Gulbenkian Institute for Molecular Medicine, uLisboa, this work provocatively feminizes the sterile field of biotech. It invites viewers to witness regeneration as a menstrual praxis—subverting bioengineering norms through a bleeding, thinking dish.
