Patterns of short-term memory are associated with characteristics of EEG brainwaves.

BLUEGRASS SHORT-TERM MEMORY EVALUATION PARADIGM

The Bluegrass Short-term Memory (BluegrassSTM) paradigm is a free (as in “free speech” and also as in “free beer”) platform that can collect behavioral (key presses) and neural (EEG) responses to evaluate and enhance working memory.

The current setup collect data in different modes, including:

  1. Resting-state eyes opened (90 seconds)
  2. Resting-state eyes closed (90 seconds)
  3. Memory training (Short version)
  4. Memory training (Long version)

The setup is designed to be hardware-agnostic and open-source at the core, meaning that the source code is open to the public and easy to modify. Also, we used the Lab Streaming Layer (LSL) to bundle everything together, which brings about a vendor-agnostic platform.

The platform supports collecting multisensory information from various neurophysiological sensors, manufactured under any vendor name, as long as being LSL-compatible. This capability extends the platform to an extent that experimenters can collect various data modalities on a single user, simultaneously. For instance, eye-tracking, heart rate, galvanic skin response, etc. along with EEG data can be concurrently recorded and analyzed.

The current version of the set up is a test-bed for evaluating short-term memory. However, we are extending it to evaluate other brain mechanisms.
