Electroencephalography (EEG) Software

Measure brain activity with EEG

Electroencephalography records electrical activity using electrodes placed on the surface of the scalp and outputs this electrical activity as a series of underlying brain waves. With EEG, you can obtain insights into how the brain works by measuring the cognitive processes underlying behavior. From language and visual processing, to executive function and memory encoding, EEG data can tell us a lot about how alert, motivated, or engaged we are, or even how difficult a task is to perform.

Quantify mental processes

Analyzing EEG data can be a complicated process. iMotions provides a range of tools to make this process as streamlined as possible. Fully customizable R Notebooks are provided to calculate power spectral density, and frontal asymmetry – all with the click of a button. Easy exports can be made to continue the analysis.

Brain-based understanding

Researchers are already using the EEG module to:

Explore neurocognitive processing of infants
Predict online music streams
Examine learning outcomes in VR
Measure emotional responses in VR environments

Features

Hardware agnostic
Connection to a variety of leading electroencephalogram (EEG) headsets such as Advanced Brain Monitoring (ABM), Neuroelectrics, and Brain Vision. iMotions also suports integration with Cedrus StimTracker, expanding research possibilities.
Complete experimental suite
Collect, visualize, analyze, and export EEG data with one software. You can use built-in iMotions EEG R Notebooks to get specific metrics or work with the raw data in your established workflow. iMotions allows you to easily sync EEG signals with other sensors.
Equipment indicators and Built-In QA
Battery level, signal strength, and impedance visualizations. Integrated quality assurance tools for before and after data collection.
Power Spectral Density Analysis
Our EEG R Notebook includes power spectral density analysis (PSD) metrics for delta, theta, alpha, beta, and gamma power. PSD can be used to understand relaxation, drowsiness, or active concentration. Power spectral density analysis is often used to study attention, cognitive workload, emotional states, sleep stages, and neurological conditions.
Frontal Asymmetry
Compare power of specific frequency bands in left and right frontal regions of the brain. Frontal Alpha Asymmetry is used when studying motivation to look at approach-avoidance behavior.
Intersubject Correlation Scores
Also known as Neural Synchrony, Intersubject Correlation allows you to study multiple respondents at a time and compare similarities in brain activity. This is a powerful metric when studying communication and social interactions.
