Research amplifiers
Neuralynx : Lynx
This amplifier has been used from xxxx to xxxx in order to record only microelectrodes
Neuralynx : ATLAS
This amplifier is used since October 2012 in order to record microelectrodes and macroelectrodes.
- maximum number of channels : 160
- samplig rate : flexible but set to 4kHz for the macroelectrdoes and 32 kHz for the microelectrodes
- input range : flexible but set to +/- 4mV
- bandpass : flexible but set to 0.1 - 1000 Hz for the macroelectrodes and 0.1 - 8000 Hz for the microelectrodes

Acquisition setups
Clinical setup
Macro and micro electrodes separated
Macro and micro electrodes together, but 2 amplifiers in parallel
Macro and micro electrodes together, only 1 amplifier, using Neuralynx CHETs
Macro and micro electrodes together, only 1 amplifier, using AdTech connectors
This setup is the classical clinical setup, using the Microimed clinical amplifier in order to record only macroelectrodes. This system is used since xxx and was the only system available until xxxx.
