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.
EEG Collection Setup
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:
Photogrammetry
If you care to use the EGI Photogrammetry System to record the electrode placement on your subject. This is useful for source localization.
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.
Collect Data
Starting Net Station
Once the net has been placed on your subject, follow these steps to properly start up Net Station.
Checking Impedance
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.
Data Storage
Where to save your data so you are a responsible user and can find it in the future.
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. Access to the form is located on the desktop of the Netstation computer, labeled steps 1 and 2:
- 1. Step 1 - logs you onto the Internet and pulls up the EEG Feedback Form
- 2. Step 2 - disconnects Internet. NOTE: This is important to do so the next tester will not be connected to the Internet while testing. Internet connection can disrupt recording
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 and/or see this feedback, email Sam at samroconnell@gmail.com .
Clean Up
Net Disinfection
After each use, rinse out and disinfect the net by following this step-by-step process.
