For unipolar recording you need as many amplifiers as you have sites to record from. For example, for 16 electrodes (not including 1 reference and 1 ground), you would need 16 EEG amplifiers. For two electrodes (again not including one reference and one ground), you would need two EEG amplifiers. Connect the reference lead (that will typically connect to an electrode on the ear or mastoid bone) to the VIN- of one of the EEG amplifiers. Then, using JUMP100C cables (JUMP100 cables in the case of B series amplifiers), connect this VIN- to all other VIN- jacks on all EEG amplifiers. Connect one ground only (to any of the EEG amplifiers) to GND. The ground lead can connect to an electrode placed on the forehead, for example. Finally, the lead for each electrode site will connect to the VIN+ of an amplifier.

You can have a maximum of four channels for a unipolar EEG setup. One SS1LA is required for each channel. Connect the reference lead (that will typically connect to an electrode on the ear or mastoid bone) to the VIN- of one of the SS1LA. Then, using JUMP100C cables, connect this VIN- to all other VIN- ports on the rest of the SS1LA cables. Connect one ground lead only to GND of one of the SS1LA cables. Finally, the lead for each electrode site will connect to the VIN+ of a SS1LA cable.
BIOPAC will show you how physiological data is seamlessly synchronized with eye tracking and stimulus presentation in one integrated solution. The talk will focus on optimizing setup, highlighting the benefits of a fully-integrated solution, and how to extract eye tracking and physiology metrics from key points, such as the cumulative average skin conductance level while a participant is focused on areas of interest.
What you will learn: • Hardware setup • Stimulus presentation creation • Setting up Areas of Interest (AOI) • Recording participant data • Analysis and reporting
BIOPAC provides software and hardware that allows research teams to study stimulus presentation data. Here are a few notable studies using BIOPAC equipment for research on stimuli’s effects using ECG and SCL data.
