StaglinCenter:EEG
The Staglin EEG Suite is part of the Staglin IMHRO Center for Cognitive Neuroscience and contains resources including:
- EGI Net Amps 300
- MR-safe EGI Net Amps 300
- EGI Photogrammetry System
- EGI HydroCel EEG Nets - S/M/L of MR and non-MR compatible versions
Follow the steps below when collecting EEG data at the Staglin EEG Suite.
We recommend giving these directions a complete once-over before you ever take data here.
Step 1: Make a Reservation
There is a Google Calendar for reserving the Staglin EEG Suite.
Request access to this calendar by emailing Agatha. When you are ready to take EEG data, make a reservation on this calendar ahead of time.
Step 2: Setup for Data Collection
Before the Subject Gets There
Booting the Computer Properly
We maintain two different versions of the NetStation program for data collection. Follow these steps to boot the computer properly to use the version you want. Remember, consistency in your data collection is important, so the version of NetStation matters.
A/V Setup
The data collection room is setup so you can pipe in audio and visual stimuli to your subejct. Follow these steps to set this up properly.
Capturing Subject Responses
If your experimental paradigm includes taking subject responses, read this to know how to record them.
Event Timing
If your experimental paradigm records when responses and stimuli occur, we has a system for accurately timing these events and recording them with the EEG signal.
Once the Subject Arrives
EEG Cap Prep and Application
EGI has some how-to's on this, and we recommend you read the manuals (located in the cabinet above the table in the EEG collection room). But we've got a step-by-step here for you.
Photogrammetry
If you care to use the EGI Photogrammetry System to record the electrode placement on your subject. This is useful for source localization.
Step 3: Collect Data
Impedance Check and Fix
You need to check the impedance of the electrodes and fix any that are too high or else your data collection will not be ideal.
Collection
Where to save your data so you are a responsible user and can find it in the future.
Step 4: Feedback Form
For quality control, we devised a feedback form that we ask researchers to fill out each time they collect data in the Staglin EEG Suite. Follow the instructions written on the Desktop Background to access and fill out this form. We actively monitor the feedback in this form. If you'd like to know see this feedback, email Edward.
