MINI-Q Introduction

Introduction to the BrainMaster “MINI-Q” Interface

The BrainMaster “MINI-Q” Interface Headbox is a switching device that connects between the trainee’s EEG sensors and a BrainMaster EEG module that provides a simple, easy way to select different electrodes for recording. This provides the ability to perform quantitative EEG measurements using a 2-channel or 4-channel device, by recording different sets of electrode pairs (2 channels at a time) or “quads” (4 channels at a time) for sampling the EEG signal. Then, by processing and displaying the EEG data, it is possible to make a determination of the EEG component values at the various sensor locations.

You will need to either place electrodes as prescribed in the accompanying documentation, or use an electrode cap. The MINI-Q is designed to be compatible with a standard cap made by Electro-Cap (Eaton, Ohio). The cap requires ear clip attachments, and a Ground connection. This is the standard cap used with the “Lexicor” NRS-24 and similar products. Any cap used with the Lexicor equipment should work properly with the MINI-Q Interface Headbox.

The accompanying material provides details of the MINI-Q device and its operation:

Guidelines for Using the BrainMaster MINI-Q 2 Interface: This procedure explains the normal use of the MINI-Q device with the BrainMaster 3.2.0 software. It provides detailed, step-by-step instructions for performing an assessment session that consists of 4, 5, or 6 sampling intervals. These typically acquire 60 seconds of EEG data, then allow for a pause while the switch position is changed, and the EEG signal stabilizes.

Electrode Assignments for BrainMaster MINI-Q Interface Box: This chart shows the top-panel electrode connections. It also shows the electrodes that are selected for each switch position, and their connections to the front panel connectors.

Connection Summary for MINI-Q EEG: Describes the connections that are made when the switch positions are selected. This chart also shows the DB-25 pin connections from the electrode cap, and the electrode identifiers from the top panel.

This material should be sufficient for users to operate and interpret results from the MINI-Q Interface Headbox. Please contact BrainMaster Technologies if you have any questions, concerns, or need assistance.
