Electroencephalography – EEG
Detect cognitive processes to learn more about how we think and behave
Measure brain activity with EEG
Get closer to understanding cognitive functioning
With EEG, you can obtain insights into how the brain works by detecting the cognitive processes underlying our behavior. From language and visual processing to executive functioning and memory encoding, EEG data can tell us a lot about how alert, motivated, or engaged we are or how difficult a task is if interpreted correctly.
EEG – recording brain waves
How does it work?
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. Measuring electrical activity from the brain is useful because it reflects how the many neurons in the brain communicate with each other via electrical impulses, and how they are associated with cognitive processes such as drowsiness/alertness, wakeful relaxation, and approach or avoidance.
The most central element of EEG is its excellent time resolution. It can take hundreds to thousands of snapshots of electrical activity within a single second. This renders EEG an ideal technology to study the precise time course of cognitive and emotional processing underlying behavior.
The iMotions EEG module
The iMotions EEG Module enables researchers to seamlessly conduct studies and validate results faster. The flexible software connects, records, and live visualizes EEG data and metrics from a range of different EEG headsets, and is a complete experimental suite for EEG, from calibration, to stimuli presentation, to export of results. Export frequency bands, frontal alpha asymmetry, PSD, and other metrics in addition to seeing full overviews of channels, signal strength, and QA tools.
