Pink Rhythmic Auricular–Mastoid Somatosensory Stimulation (PRAMS): A Sensory Modulation Method Based on 1/f Noise and Rhythmic Envelopes

Pink Rhythmic Auricular–Mastoid Somatosensory Stimulation (PRAMS) is a sensory modulation method based on the combination of pink noise (1/f spectral distribution) and rhythmic amplitude envelopes applied through auricular and mastoid sensory pathways. The method organizes rhythmic modulation within physiologically informed frequency windows associated with neural oscillatory dynamics. PRAMS integrates principles from neuroscience, complex systems theory, and stochastic signal processing to explore interactions between rhythmic sensory stimulation and neural regulatory dynamics. The PRAMS method (Pink Rhythmic Auricular–Mastoid Somatosensory Stimulation) was originally developed by Heitor Della Rovere. This record includes the conceptual paper describing the theoretical framework, signal architecture, and mathematical formulation of the PRAMS method.
