The AE-120A EEG Head Set with the electrodes is then attached to the patient's head using the head set's chin, top, and rear straps. With the head set turned on and secured in place, the head set acquires and amplifies electrical activity via EEG electrodes placed in contact with the patient's scalp. The captured waveforms from these signals are transmitted wirelessly via Bluetooth to a Nihon Kohden specified electroencephalograph through the AE-120A EEG Head Set and receiver. The head set outputs the collected brain electrical activity to the computer component of the electroencephalograph system where a medical professional can review and interpret the information. The AE-120A EEG Head Set has 8 channels for measurement along with one reference and one Z electrode. The electrodes are fixed into position with the head set to approximate the 10-20 electrode positions. The AE-120A EEG Head Set is designed to work with the Nihon Kohden EEG-1200A series and EEG-9100, cleared in K080546 and K011204, respectively. The associated system software is used to facilitate the communication and display of the information from the head set. #### Indications for Use The AE-120A EEG Head Set is intended to amplify, capture, and wirelessly transmit electrical activity of the brain for review by a trained medical professional using the previously cleared and validated Nihon Kohden electroencephalograph systems (EEG-1200A series and EEG-9100) to assist in the diagnosis of neurological disorders. The AE-120A EEG Head Set and its associated EEG Software do not provide any diagnostic conclusion or automated alerts of an adverse clinical event about a patient's condition. The device is intended for use by trained medical professionals in a medical facility such as a physician's office, laboratory, or clinic. The device is intended for use on adults (ages 18 and above). (Rx Only) #### Predicate Devices The AE-120A EEG Head Set is substantially equivalent to the Ceribell Pocket EEG with the Ceribell Instant EEG Headband. Table 1, below, lists the primary predicate device, K170363 (headbox, processing unit, basic software needed to display, store, and archive EEG and allow user-only annotation and marking; does NOT include electrodes, more complex software used to {5}------------------------------------------------ analyze EEG or automatically detect events).
