SYNAPTICON is an artistic research artifact at the intersection of neuro-hacking, brain-computer interfaces (BCIs), and foundation models, probing new territories of human expression, aesthetics, and AI alignment. Envisioning a cognitive “Panopticon” where biological and synthetic intelligent systems converge, it enables a pipeline that couples temporal neural dynamics with pre-trained language models and operationalizes them in a closed loop for creative performance. At its core lies a live “Brain Waves-to-Natural Language-to-Aesthetics” system that translates neural states into decoded speech, and then into immersive multimodal output, shaping altered perceptual and aesthetic experiences and inviting audiences to directly engage with the creator’s mind. SYNAPTICON contributes to discussions on post-AGI safe and meaningful trajectories: human–AI co-creation and alignment, neuroaesthetics, mental privacy, and neurorights.
