Device Story
Cervello Bio-Potential Signal Acquisition System is a multi-channel, multi-modal physiological monitoring platform. It acquires bio-potential signals (EEG, PSG, ECoG, EMG, ECG, EOG, EP) via user-supplied electrodes. The system consists of hardware amplifiers (Cervello or NeuroPort) and software (Cervello/Central). Inputs are digitized and stored in RAM/memory cards or PC-based systems for later review. Used in clinics, hospitals, ORs, and sleep labs by trained professionals. The device provides raw signal display and storage; it does not perform automated analysis, diagnostic interpretation, or physiologic alarming. Healthcare providers use the displayed data to support clinical decision-making. The system benefits patients by enabling high-fidelity recording of neurological and physiological signals for expert review.
Clinical Evidence
Bench testing only. No clinical data provided. Performance testing included third-party IEC 60601 compliance, shipping validation, and internal cart tipping requirements. Software verification and validation were performed to support the integration of Cervello software with NeuroPort hardware.
Technological Characteristics
Multi-channel bio-potential acquisition system. Hardware: Cervello Amplifier or NeuroPort system. Connectivity: PC-based (Windows XP/7/Server 2008 R2). A/D conversion: 16-bit. Sampling rate: up to 30,000 Hz. Input impedance: 1000 Megohm. Frequency response: 0.3-7.5 kHz (Elite) or 0.15-220 Hz (Ambulatory/Basic). CMRR: >90 dB. Power: 120 VAC or battery-powered (Ambulatory). Sterilization: N/A (non-invasive). Software: Cervello/Central for signal display and storage.
Indications for Use
Indicated for acquisition, storage, and display of physiological signals (EEG, PSG, ECoG, EMG, ECG, EOG, EP) in adults and pediatrics. Intended for use by trained physicians, technicians, or medical professionals in clinics, hospitals, ORs, epilepsy units, and sleep labs. Not for automated diagnosis or physiologic alarming.

8. Description: Multi-Channel, Multi-Modal Physiological Monitoring System
Cervello Ambulatory - This system uses the Cervello Amplifier in the ambulatory environment and provides up to 64 input channels for EEG and PSG studies. The Amplifier is battery powered during recording; the internal microcontroller stores the data in a RAM buffer and memory card where it can be downloaded later for review by a physician.
Cervello Basic - This is a PC-based clinician-oriented EEG and/or PSG monitoring system that provides between up to 128 channels for EEG recording using the Cervello Amplifier. Data is displayed on a monitor using the Cervello Basic software program and video capabilities are available.
Cervello Elite -- This is a PC-based clinician-oriented monitoring system that provides up to 256 channels for recording bio-potentials such as electroencephalography (EEG), electromyography (EMG), electroencephalography (ECG), electrooculography (EOG), electrocorticography (ECoG) and evoked potential (EP) using the NeuroPort Bio-Potential System Hardware and operates both the Cervello (Basic) and the Central Software. Video capabilities are available.
In all cases, and as with the predicate devices, the Cervello Basic, Ambulatory and Elite Systems are not monitoring systems. No physiologic alarms are provided. The acquisition and display of bio-potential signals is for the interpretation and use of the clinician. The devices do not make any judgment of normality or abnormality of the displayed signals and the software is not intended to do automatic analysis of the recorded signals
- The Company does not sell any of the following accessories: EEG electrodes, accessory cables, oximeter sensors, 9. cannulae and respiratory effort sensors. Predicate Device(s):
