shopper studies, user interaction studies) What are the reasons for ambulatory EEG?Īmbulatory EEG is usually carried out for the following reasons: This means not only that there will be more data, but also more movement, and (likely) a wide range of interacting factors will impact the data.
While this has been ideal for assessing brain activity in specific settings, sometimes a different approach is required.Īmbulatory EEG is the method of collecting EEG data over a long period of time (this can be anything from hours to days) in naturalistic settings. While the level of visual information received isn’t as detailed as some other neuroimaging techniques (such as fMRI, or functional magnetic resonance imaging), the temporal resolution, combined with the portability, relative affordability, and ease-of-use means that EEG is one of – if not the most – commonly used neuroimaging methods.ĮEG is often used within strictly controlled experimental settings – scenarios in which data is collected for a set amount of time, with little movement, and clearly defined stimuli. There are several neuroimaging devices available, but none of them give such a high level of temporal resolution as EEG. Attempts to understand human behavior can involve the measurement of a range of physiological signals, but getting closer to the brain requires equipment to record its activity. It’s an age-old concept in science that if you want to understand something, you first have to measure it.
