Macro and Macro2+stim

Macroelectrode Recording and Stimulation

Macro and Macro2+stim

Built for macroelectrodes, such as surface EEG, implanted EEG or sEEG, ECoG and EMG electrodes, the Macro front end records slower signals with a large input range that covers a wide variety of signal types and applications.

The Macro2+stim adds stimulation from 1µA to 15mA on any or all channels simultaneously. With a maximum stimulation current of 15mA, the Macro2+stim matches common clinical neurostimulators.

Features

• Integrated filtering, amplification, and 24-bit digitization for high-fidelity signal acquisition
• Stimulation on any or all channels simultaneously
• Programmatic control of waveforms and train parameters
• Exhausting for fast recovery following stimulation: all channels discharge quickly by shorting to ground over a physical resistor (5 selectable values on the ASIC), giving control over discharging
