Oneiris is an interactive art installation that combines brain-computer interface technology, generative artificial intelligence, and Indigenous Lakota dream symbols. Participants wear an EEG headset to provide dream narratives and sketches, which are processed by AI to create evolving visual dreamscapes. The installation uses a Medicine Wheel interface to give feedback on cognitive states and archives contributions in a collective semantic map. It aims to ethically integrate Indigenous epistemologies with neuroscience and AI, fostering cross-cultural dialogue and introspection about personal dreams as culturally embedded phenomena.
Expert Buddhist monks practicing Samatha (focused-attention) and Vipassana (open-monitoring) meditation showed increased neural signal complexity and widespread reductions in gamma-band long-range temporal correlations and 1/f slope compared to resting state. Analysis of deviation from criticality revealed distinct computational states between the two practices, suggesting their different phenomenological properties arise from specific dynamic characteristics. Contrary to most prior reports, oscillatory gamma power decreased during meditation, a difference attributed to correcting the power spectrum for broadband 1/f activity. These findings advance understanding of neural processes underlying focused-attention and open-monitoring meditation.
