NeurOne close-up

NeurOne Tesla provides precise signal measurement with 24-bit AD conversion, precise temporal synchronization with the scanner clock enabled by Tesla’s 80 kHz sample rate and an optimal combination of the spatial information from fMRI with the abundant temporal information from EEG.

NeurOne Tesla is innovative research system developed by Mega Electronics. This neuroscience measurement system offers more accuracy, cleaner signal, faster sampling, modular solution and more flexibility and expandability by utilizing the latest advances in digital signal processing.

NeurOne is a versatile system and it can be used widely in different neuroscience and psychophysiological applications. NeurOne Tesla is especially designed for use together with transcranial magnetic stimulators having extremely large dynamic range and special reduction technology to remove magnetic artefacts in short latencies. Advanced amplifier design enables using both AC and DC recording modes the way you want.  Innovative Tesla MRI amplifier brings MRI compatibility to NeurOne.NeurOne close-up 2
