Grant & Publication Highlights

The fabric of the primate neocortex and the origin of mental representations: From transcriptomics to single neurons and neuronal networks ($625,000, 5 years)

A distinctive feature of intelligence is being able to represent objects “in the mind,” without the need to see them directly. The NeuroNex – Working Memory (NXWM) initiative will systematically explore the specializations that allows the brain to produce mental representations. The international, multicentre team – including 16 labs at nine institutions in the U.S., Canada and Germany – will scrutinize for new molecules, cell types and patterns of brain activity and behaviour, then use advanced computational techniques to assemble the knowledge in an integrated quantitative model of “mental brain networks.” CAMH’s Krembil Centre for Neuroinformatics will co-develop advanced computational techniques for the initiative.

Identification of functional connectivity biomarkers of social cognition across schizophrenia and autism:  A longitudinal and dimensional approach ($566,101, 4 years)

Social cognition has emerged as an important predictor of functional outcome in individuals with schizophrenia spectrum disorders (SSD) and autism spectrum disorders (ASD). Even though social cognitive impairments are major drivers of the severe societal and personal impact of these disorders, few treatment options for social deficits are available. This project continues ongoing work that studies social processes in individuals with SSD, ASD and typically developing controls, using a comprehensive battery of social, cognitive, clinical and functional behavioural assessments, and multimodal neuroimaging. The first aim of this study will be to refine “latent” brain-behaviour dimensions cutting across participants with SSD or ASD or typically developing controls. The second aim is to retest a subset of participants and establish whether these proposed underlying dimensions are stable over time. These findings could inform the development of mechanism-based treatments to enhance social cognition and social function in people with SSD or ASD.
