LabScribe EEG Analysis Module

The LS-30EEG Analysis Module for LabScribe software allows investigators to look at EEG data using a number of preset standard EEG montages.  The alpha, beta, theta and delta frequency distribution is calculated for each electrode combination and displayed graphically within the LabScribe EEG interface.  Data can be manually analyzed within LabScribe or segments of ERP data parsed for export to a .txt, .csv  EDF or MatLab file format for further analysis.

Features:

• Includes built-in stimulus presentation/experiment builder software like OpenSesame
• Play sound, display images or videos as part of predefined experimental protocols
• Export of data in text, EDF or MatLab format allows for post-processing with many EEG analysis programs
• Easily view data using a variety of preset montages
• Calculates and visually displays EEG power in the  alpha, beta, theta, delta bands
• Integrates with other stimulus presentation experiment builder software such as OpenSesame

 

LabScribe ERP Analysis Module

An ERP (Event Related Potential) occurs in response to a specific stimulus. This stimulus may be a sensory, cognitive, or motor event. The ERP is the time-locked average of an EEG over many trials involving the same event. The repetition reduces the EEG's inherent signal to noise ratio, so the specific potential related to the event is displayed.

The ERP Analysis Module, breaks up the data file into different segment corresponding to the stimulus, The segments corresponding to a stimulus can then be averaged and location of the peak response can be calculated.
