Introduction:
The Quebec 1000 Families (Q1K) project aims to study a large cohort of families with at least one member with an autism spectrum condition (ASC). As part of its Open Science philosophy, it also aims to design an open and reusable experimental protocol and open-source tools for ASC research. Q1K is a three-phase multi-site project, including 1) a research registry, 2) light phenotyping, and 3) deep phenotyping. The latter phase builds on collected demographics, questionnaires, and biosamples and adds multimodal deep phenotyping, including high-density EEG, eye tracking (ET), behavioral, and 7T MRI data. Here, we focus on Q1K's EEG/ET experimental protocol and discuss its general approach, design philosophy, multimodal EEG/ET integration, and open release.
Methods:
We aim to deep-phenotype 200 persons with ASC and at least one of their family members. We have already collected about a quarter of that target sample. We aim to build a strongly multimodal dataset assessing a wide array of constructs, built on well-established tasks, and including the full spectrum of symptoms severity and a wide age range (5-89 years old). We used tasks developed and tested in infants and toddlers to ensure inclusivity. We aimed for a 1-hour protocol. Understanding that some participants may be unable to participate in the whole protocol (due to lack of time or sensory sensitivity), we ordered the tasks from higher to lower priority. We also considered the comfort of the participants by avoiding running back-to-back boring (e.g., oddball), passive (e.g., resting state), or "abrasive" tasks (e.g., pupillary light reflex and the visual steady state tasks). We first ran the resting state task to avoid "spillover" effects from more engaging/stimulating tasks on oscillatory measures. In order, the protocol includes the following tasks: 1) resting-state (Neuhaus et al., 2021), 2) tone oddball (Green et al., 2020), 3) gap overlap task (Portugal et al., 2021), 4) visual steady-state (Lalancette et al., 2022), 5) auditory steady-state (Edgar et al., 2016), 6) naturalistic social preference (Saez de Urabain et al., 2017), 7) pupillary light reflexes (Nyström et al., 2018), and 8) visual search task (Gliga et al., 2015). These tasks were selected to cover a wide range of constructs, including general brain state (1), sensory (2, 4, 5), perception (4, 5, 8), attention (2, 3), executive function (3), social motivation (6), and sensorimotor (7).
The recording system includes an EGI 128-channel system synchronized with an EyeLink 1000+ eye-tracking system. Robust synchronization with visual and auditory stimuli is ensured by a Cedrus StimTracker box connected to the audio output and two photodiodes mounted on the presentation screen. EEG and ET data are synchronized and integrated into BIDS format recordings, allowing direct comparison of eye gaze position and pupil signals with EEG signals. A software infrastructure has been implemented to preprocess the dataset into a state optimal for sharing and reuse.
Results:
Figure 1 illustrates the high quality (high inter-trial coherence indicating reliable synchronization and high signal-to-noise ratio) and the excellent between-site reliability. Figure 2 demonstrates the EEG/ET integration. Besides sharing the data, we are sharing the protocol we designed (as Experiment Builder files) and the software infrastructure we implemented to convert the source files in BIDS format, preprocess them using the PyLossless pipeline (Huberty, Desjardins, et al., 2024), and post-process them in epoched data for easier analyses. The resources released by this project will support the reuse and easy deployment of this protocol for other projects.

Conclusions:
Q1K was designed as a large-cohort, inclusive, Open Science project. By releasing the dataset, the protocol, and the software architecture used to run its EEG/ET protocol, we hope to support standardization and data pooling into larger, more diverse datasets for the study of ASC.

The Open Science Special Interest Group (OSSIG) is introducing a reproducibility challenge for OHBM 2025. This new initiative aims to enhance the reproducibility of scientific results and foster collaborations between labs. Teams will consist of a “source” party and a “reproducing” party, and will be evaluated on the success of their replication, the openness of the source work, and additional deliverables. Click here for more information.
Propose your OHBM abstract(s) as source work for future OHBM meetings by selecting one of the following options:
