Reserving the EEG Suite
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.
Data Collection
Booting the Computer Properly
We maintain three different versions of the NetStation program for data collection: 4.4, 4.5, and 5.0. These are found on the hard drives labeled EGI-stable, EGI-dev, and EGI-experimental, respectively.
Follow these steps to boot the computer properly to use the version you want: StaglinCenter:EEG:BootVolume
Remember, consistency in your data collection is important, so the version of NetStation matters.
Testing Setup
This is an outline of a basic testing setup to do an audio and visual EEG setup in the EEG suite:
If you are working on a current project, please follow the protocol regarding your project by going to the project page:
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.
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.
