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.

• StaglinCenter:EEG:BootVolume

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.

• StaglinCenter:EEG:A/V

Capturing Subject Responses

If your experimental paradigm includes taking subject responses, read this to know how to record them.

• StaglinCenter:EEG:Responses

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.

• StaglinCenter:EEG:Timing

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.

• StaglinCenter:EEG:Net

Photogrammetry

If you care to use the EGI Photogrammetry System to record the electrode placement on your subject. This is useful for source localization.

• StaglinCenter:EEG:Photogrammetry

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.

• StaglinCenter:EEG:StartingNetStation

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.

• StaglinCenter:EEG:ImpedanceCheck

Collection

Where to save your data so you are a responsible user and can find it in the future.

• StaglinCenter:EEG:Collect

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.

• StaglinCenter:EEG:Disinfect

Troubleshooting and Denoising

• Checking Ground
• Checking for wire loops
• Checking Scanner Settings
• Checking Cap Electrodes for Noise

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
