Improvements in 2.5 software

 

This document summarizes the important differences and improvements in the BrainMaster 2.5 BMT (Basic Modules for Training) software.

 

 

Latest 2.5SE Improvements

 

Use the link below for the latest 2.5SE Improvements since 2.5 was released, including the new Event Wizard, Math Wizard, Flash Player, renamable component bands, Dynamic Screen Layout, HEG screens and protocols, and more:

March 2006 2.5SE Update Documentation

 

 

The 2.5 software is capable of all of the functions in 2.0SE.  In addition, it adds the following capabilities:

 

 

The 2.5 software will support all existing “2.0-enabled” 2E modules, in addition to the 2EW wideband modules.  When used with a 2E modules, the software can operate at either 120 or 256 samples/second.  When used with the 2E module, the 256 sampling rate provides enhanced frequency accuracy and timing response, in comparison to 120 samples/second

 

The 2.5 software installation leaves any pre-installed 2.0 or 2.0SE software intact.  The 2.5 desktop icon will be added to any icons that are already there.  You can then run either the 2.5 software, or the previously installed 2.0/2.0SE software.  Note that the software programs will “share” the login information, and any information you log in with will be visible to both programs.  Also note that a 2.5 passkey will work with the 2.0 or 2.0SE software as well.  So to use both sets of software, you need only enter your 2.5 passkey, and it will be visible and work for both software versions.

 

Note that you will have a new passkey to log into the 2.5 software.  Once you install the 2.5 software, you will need to enter the new passkey you received with the 2.5 software.  This new passkey will also work with 2.0SE software, if you use it on the same PC.

 

Even when used with existing 2E modules, 2.5 has significant benefits.  By sampling the EEG data at 256 samples/second, time response and displays are improved.  In addition, it becomes possible to employ the built-in notch filters to remove 60Hz or 50Hz interference.  Thus, improved signal quality and reduced noise can be achieved with existing equipment, by using the 2.5 software.

 

Operation at 256 samples/second, operating bandwidth up to 64 Hz

 

 

Data Channels Setup screen for 2.5 now includes selections for the sampling rate, and to select the Input Notch Filters.  NOTE: The input notch filters operate only at 256 samples per second.  If they are selected during 120 samples per second operation, they will have no effect.

 

 

A variety of new screens are available under the Additional Software/Browse Button:

 

 

The browser looks as follows:

 

 

Inclusion of long (30 minute) trend plot especially useful for alpha/theta crossover work:

 

 

The following screen shows the 2-channel Lissajous plot.  This plot shows the 2 EEG channels plotted against each other.  It is possible to see phase relationships, coherence, and amplitude information regarding the 2 channels.  This display is only useful when 2 channels of EEG are being measured.

 

 

Example of 2-channel multiple component Lissajous plots:

 

 

 

The following shows the Return Map View.  This shows a component plotted against itself, with a delay introduced.  These are called “return maps” because the signal is seen to return upon itself cyclically, revealing complex dynamics, and providing a very rapid, informative display.

 

 

Multicomponent Return Map:

 

 

 

Support of optional StimFlash software:  The following is the control panel for the current StimFlash software.  This is documented separately in the 2.5 software online documentation: Press “Product Manuals” from the Setup/Home screen and scroll down to the appropriate link.

 

 

Support of optional Interactor Cushion software.  This shows the Interactor Cushion control panel.  This software is documented separately in the 2.5 software online documentation: Press “Product Manuals” from the Setup/Home screen and scroll down to the appropriate link.

 

 

 

 

 

 

New BrainScape Display

 

The BrainScape Joint Time-Frequency Analysis (JTFA) display is included in the 2.5 software under the “Spectral” button on the “Window” control panel.  See the following document for example displays

Two-channel BrainScape Displays

 

 

 

 

 

New MultiMedia Controller
