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 (alenarto @ ucla.edu). 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 Net 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
Starting Net Station
Once the net has been placed on your subject, follow these steps to properly start up Net Station.
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.
The identification names of each net can be found on the plug.
We actively monitor the feedback in this form. If you'd like to know see this feedback, email Edward at eplau @ ucla.edu .
Step 5: Cleaning Up
Net Disinfection
After each use, rinse out and disinfect the net by following this step-by-step process.
Troubleshooting and Denoising
EEG Suite supplies
Where to find EEG supplies in the lab
Most of the supplies needed for EEG testing is located in the EEG net room in the wooden cabinet by the sink. If you open the left cabinet, on the main top shelf, most of the supplies you will need for testing will be located in the plastic bin labeled with EEG supplies. You will find the following in that bin:
- scissors
- red wax pencil
- tape measure
- spandages
- disposable EEG/MR electrodes
Johnson's baby shampoo, EEG solution salt, extra electrodes, the EGI net manual, and EGI net boxes along with their respective measuring spoons are usually located on top of the cabinet by the sink. The electrodes and the net boxes are in the cardboard boxes on top of the cabinet.
In the EEG Suite's left testing room, you will find remaining supplies in the cabinets to the left of the table with the computer monitor and the EGI amp. The cabinet shelves are labeled with these items:
- latex gloves
- disinfectant
- pipettes
- medical tape
- EEG salt
If you see that something has run out, check the following places to see if extras are stored:
- the wooden cabinet by the sink the EEG net room (Johnson's baby shampoo and spandages may be hiding in the shelf below the plastic bins, in the bottom drawers, or on top of the cabinet)
- the cabinets in the EEG suite (currently, there are MANY boxes in the right-most cabinet in the testing room and some on the top shelf of the cabinet where the Stimulus computer lives).
NOTE: If something has completely run out, there is an emergency supply located in the shop, but please ask Edward, Sam, or Cameron for these supplies. BUT ONLY FOR EMERGENCIES.
Where to order EEG supplies
We have had success ordering supplies from the following places. The ones ordered from online sites accept purchase orders:
- pipettes (5.8mL, non-sterile): Fisher Scientific
- MT Spandages (MT07, 7-inch spandage, 25 yards): Vitality Medical
- Johnson's baby shampoo: This is very hard to find online, so purchase from a store (CVS, Target, Walgreens, etc.) and give the bank statement and receipt to Jun or Malina for a reimbursement.
- EGI salt and disinfectant: order from EGI
- disposable EEG/MRI electrodes (EL509, 100 electrodes/box): Biopac Systems, Inc.
Current supply stock
- pipettes: ordered 2014.01.10 - 10 boxes of 500 pipettes
- Johnson's baby shampoo: ordered 2014.01.20 - 8 bottles
- MT Spandages: ordered 2014.02.10 - 10 boxes
