64 Channel amplifier
Neuvo sets a new standard in amplifier technology, providing a system suitable for recording everything from high sampling rate (10,000 Hz) Auditory Brain Stem recordings and Spike Spindles to true DC recordings of CNV and P300.
The Neuvo can be used in conjunction with the CURRY software, providing a complete acquisition and analysis system, or with the ACCESS SDK, allowing user’s custom built software to control and acquire data from the system.
Neuvo can also be used with the STIM2 system for integrated and accurate stimulus presentation or will accept TTL pulses from third party systems.
Neuvo can be used with the QuikCap, to provide fast and simple electrode placement or will accept any touch proof electrode as well. Grid, depth and microelectrodes may also be used with the Neuvo.
Utilizing the latest technology, Neuvo allows for discrete monopolar and bipolar channels, enhancing the flexibility of recordings. Linking headboxes together allows more than 500 channels to be recorded.
A 64-channel Neuvo EEG system has one headbox, with 68 channels in total.
Maximum Sampling Rate: 10,000 Per Channel all channels driven
Faster sampling rates allow for more accurate sampling of the analog data being recorded. Signals such as Auditory Brain Stem Response require these faster rates, while typical ERP measures benefit from increased resolution.
Sampling Method: All Channels Sampled Simultaneously
Current technology eliminates the problems associated with sample and hold circuits. Utilizing a dedicated 24-bit A to D chip for each channel, the Neuvo enhances resolution and accuracy of each sample by ensuring a more valid measure of the data without decay or skew.
The 24-bit resolution allows for even the most subtle differences in amplitude to be measured accurately.
Recording Bandwidth: DC to 3500 Hz
Many slow potentials (i.e., P300, MMN, CNV) have components that can only be measured accurately using a DC amplifier. DC amplifiers are also not subject to the AC coupled, filter time constant that distorts recordings after an artifact. The high frequency end of the Neuvo’s range allows for more accurate recording of the fastest frequencies.
Active Noise Cancellation: Utilizing advanced driven reference technology
Neuvo sets a new standard for amplifier design, both in terms of safety and signal quality. Actively sampling environmental noise, and applying an antiphase signal to eliminate that noise, elevates the CMRR to unprecedented levels. This technology also provides increased patient protection.
>10 G Ohm Input Impedance: Allows standard impedance or fast preparation to be obtained
Neuvo allows you to choose on a subject by subject basis to prepare the scalp electrode impedance to the scientifically accepted levels or to record with high impedance, due to time or bject constraints. This flexibility allows you the option to maximize your data collection for each subject and collect the best data the situation allows.
Portability and Integration: Small Package, big features
Digital amplifiers are typically small and thus portable, but portability also means unpredictable environmental noise. Neuvo has built in technology to function even in the worst electromagnetic fields.
