The Bion 11 neurovestibular hardware measures vestibular nuclei response (VNR) and direction and velocity of primate head movement, driven by rotational and oscillating devices and the associated neurovestibular response due to microgravity exposure.
Subsystems
Sensors: Sensors and electrodes measured electrooculogram (EOG), electroencephalogram (EEG), head motion velocity (HMV), VNR, and head position.
Signal Processing: The Head Electronics Assembly (HEA) preconditioned signals from the sensors and provided signal pass through or preamplification for EOG, VNR, EEG, and brain temperature measurements. The HEA consisted of the mother board, which provided preamplification of EEG, EOG, and VNR signals, and multiplexing of VNR signals; the daughter board, which provided a connection point for implanted sensors; and the baby board, which provided a connection point for ground-based testing. The metal cap on the top of the HEA, attached to the head ring, held the Head Motion Velocity (HMV) pitch and yaw sensors.
