This device samples some 10,000 well-distributed neurons throughout the player's brainpan. It responds with a specific tone and texture when each neuron fires, producing a pseudo-rhythmic tonal surf effect. With significant biofeedback training and lucky placement of the neural sensors, a being can control anywhere from approximately 20% to the record 72.94% of the various textural tonal effects. This soundscape is usually quite calming and peaceful, unless there are unlucky placement of the filaments.
Note that the device insinuates nanofilaments each time it is picked up, and therefore each musician must spend hours rekeying their instincts and skills to deal with the new placement. It automatically disconnects when the being achieves REM sleep to prevent damage to itself - at least, that's according to the few manuals that have been recovered. What kind of damage is not specified.
A cerebral siren concert was credited with the enlightenment of "the thirty-one" in 2556 in a small hab orbiting Ain Soph Aur. The thirty-one were the remnants of a small group of hermetic scholars whose faith included strenuous recreation en masse. The thirty-one survivors of the incident (there were approximately 100 more beings driven psychotic, catatonic, or self-destructive by the event) went on to spread their conceptualizations of the music of the spheres over a period of approximately 20 years. At the end of this time, all thirty one disappeared simultaneously. No leads have ever been found as to what actually happened.
