Meet Cortivision at fNIRS UK 2023

We are delighted to announce our presence at fNIRS UK 2023 in Colchester. The conference starts on 14 ending on 15 September. During these days we can experience highly productive, interdisciplinary two days symposium on campus. A wide-range selection of workshops, tutorials, keynotes and latest research posters & presentations sessions for the community of researchers and practitioners in Functional Near Infrared Spectroscopy in Europe [1]. 

Take part in a workshop that we have prepared on “Introductory to CortiPrism fNIRS signal processing software: from artifact correction to group-level analysis”. It will take place on the first day of the conference (14 September) at 15:30. During the workshop, you will have the opportunity to learn different preprocessing methods such as TDDR, removal of bad channels based on the Scalp Coupling Index (SCI) or adding physiological and motion signals to GLM equations. In addition, each step is run from a graphical interface, so you do not need coding skills. Our Cortiprism application allows the raw data to be analysed into final results using full pipelines with the most commonly used algorithms.


When the .snirf file with raw data is opened, the signal and its characteristic will be displayed on the Prepocessing tab. The “Preprocessing” tab is organized into four sections: signal quality display, preprocessing control panel, time-series display, and channel selector panel. Here we have the opportunity to assess the quality of the signal and then take steps to improve its characteristics by removing bad channels, filtering or correcting artifacts.

After establishing the signal processing pipeline on the ‘Preprocessing’ tab, trials can be averaged across conditions on the ‘Trial average’ tab. It’s organized into three sections: channel montage display and control, average response display, and averaging options panel. This tab, in turn, allows us to present the results in the form of a simple averaging of the processed signal or GLM parameters, which we can then export for statistical analysis.

Finally, results of simple averaging or GLM-based averaging can be visualized in the form of projection on the cortical model on the ‘Cortical visualization tab. The “Cortical visualization” tab is organized into three sections: channels montage display and control, cortical surface visualization, visualization control panel. The last tab allows us to create visualizations of our research results, for publication or other purposes.

Throughout the poster session, you will have the opportunity to see our work on left DLPFC hemodynamic activation and pupil dilation during the n-back task. It concerns the integration of the Photon Cap and the Tobii Fusion eye-tracker.

The most recent yet varied advancements in neuroscience will be reflected by fostering the development of a meeting with an excellent scientific agenda. This event is waiting for you! It is the moment where you get the chance to network with experts in their fields, taking part in a series of remarkable presentations and posters.

At this event you will have the opportunity to meet our team Cortivision as platinum sponsors. This is an amazing opportunity to talk together about the research, and potential questions that may arise about our Photon Cap device.
