Researchers in this field aim to understand the brain mechanisms supporting cognitive and social behavior in humans, and how these mechanisms may be altered in various disease models.
As this often requires bringing together a data of different types, one software to work as an integration platform is ideal. The Observer XT is that platform.
The Observer XT is a professional research software often used in human neuroscience research. It allows for easy integration of multi-modal data, such as fMRI data, or other physiological measurements such as EEG or EMG, along with manually coded behaviors of interest. For example, synchronizing EEG data with video recordings allows the behaviors of interest to be linked to EEG data points.
Eye tracking data can also be integrated into The Observer XT. Eye trackers are particularly useful for investigating brain damage, neurological diseases, and general visual and neurological functions.
Combining multiple data streams such as manual event coding, eye tracking, and even facial expression data provides researchers a better overview and understanding of all that occurs during a research session.
“Having the videos directly linked to The Observer XT via Media Recorder along with custom data imported directly into the program, saved us so much time and effort. Most importantly however, the level of support and service has been invaluable and definitely a key point of difference for a product in this space (especially for research which requires various customization).”

Facial expression analysis
Next, facial expression data can also be integrated into The Observer XT. FaceReader is the most robust tool on the market for automatic analysis of facial expressions. It is used in neuroscience research to assess social behavior, and even as a treatment or diagnostic tool for autism patients.
FaceReader automatically classifies happy, sad, scared, disgusted, surprised, angry, neutral, and contempt, and also provides gaze direction, head orientation, and personal characteristics such as gender and age. To provide further detail, analysis of 20 commonly used facial action units is available.
Data integration is essential
Prof. Julien Mercier from L'Université du Québec à Montréal (UQAM) is studying educational research. His lab is looking at refined brain information over time, involving the cognition and the affect of the learner. He states: "Data integration is really where everything begins and ends."
