Electromagnetic waves permeate our surroundings and our very being, unrestrained by flesh, bone, or spatial boundaries. Sutela describes her work 40 Hz as a neuroactive sculpture. Consisting of blown glass and programmable LEDs, the works embody the electrophysiological foundations of gamma waves. Governed by unique light programs, the glass heads pulse within frequency ranges corresponding to the electrical oscillations normally present in the human brain while perceiving and remembering (40 Hz). Channeling the esoteric roots of electric and light therapies, the sculptures work to induce open, boundless forms of existence part and parcel of the wider environment.

The sculpture is part of a cycle of works originating in Sutela’s commission for Biennale de l'Image en Mouvement 2024 at CAC Genève. Another work in the series was presented at Kunsthalle Bremen as part of the Pauli-Preis 2024 exhibition.
