A-CAP - Advancing Concussion Assessment in Pediatrics: a prospective, concurrent cohort, longitudinal study of mild traumatic brain injury in children
|
A-CAP was a prospective, longitudinal cohort study of children aged 8.00-16.99 years with either mTBI or OI, recruited during acute emergency department (ED) visits at five sites from the Pediatric Emergency Research Canada network from September 2016 to December 2018. |

CBN18-ENABLE - Enabling Neuroscience research Approaches for Brain, feeLings and Emotions
|
More than 350 million people worldwide live with depression and bipolar disorders, yet finding the right treatment often involves trial and error. Advancing precision psychiatry requires large, standardized datasets that reflect real-world populations. The Enabling Neuroscience research Approaches for Brain, feeLings and Emotions (ENABLE) was developed in partnership with patients and supported by the CAN-BIND Network, Brain Canada and the Ontario Brain Institute. |

Multi-modal Imaging Investigations of Individuals with Temporal Lobe Epilepsy and Excisions
|
Clinical and imaging data on 118 patients with temporal lobe epilepsy (TLE), 72 who underwent excisions with post-operative outcomes recorded, are included from two epilepsy surgical centres in Ontario, Canada. Also included are MRI scans from 46 controls from the two scanners. These deeply phenotyped cases can be used to derive imaging correlates of TLE in relation to clinical features and surgical outcomes. MRI data from controls and limited EEG data are also available.

Ontario Neurodegenerative Disease Research Initiative (ONDRI): Parallel pathways for language processing: functional dissociation and compensation release
|
This controlled data release contains data from a series of studies conducted at Baycrest Hospital concerning the role of dorsal and ventral language pathways in both brain hemispheres in language processing. The studies examined neural reactivity to semantic and syntactic anomalies in written and auditory presentation formats, although some used written presentation only.

CP-NET Clinical Database Platform: Genomic Architecture of CP (Whole Genome Sequencing)
|
The CP-NET Clinical Database recruits children born in 2009 or later with a confirmed diagnosis of cerebral palsy (CP) and contains data on clinically relevant risk factors, neuroimaging information, and neurodevelopmental functioning including psychosocial and participation outcomes.
This released dataset has whole genome sequencing data (WGS) on 221 children and youth with CP and their biological parents (656 samples). WGS was performed on DNA extracted from saliva on the Illumina HiSeq X platform, and the resulting CRAM files are provided. |
