What are the genes and pathways disrupted in neurodevelopmental disorders such as autism? We are using a combination of computational and wet-bench approaches to elucidate novel signal cascades important for the pathophysiology of autism. We are focused on identifying the neural circuits and cell-type contributions of these genes to brain development. We are also developing new rodent models for testing the behavioral consequences of modifying these genes.
What are the human-specific gene expression signatures and signaling pathways? We are taking a comparative genomics approach to identify genes that have been modified in the human brain. Genes of interest are being further examined using both human neuronal cultures and animal models.
Which genes are important for human cognition from a functional standpoint? We are examining the correspondence of human brain gene expression with measurements of human brain activity. We are also examining how these correlations are disrupted in cognitive disorders.
Memory encoding is an essential step for all learning. However, the genetic and molecular mechanisms underlying human memory encoding remain poorly understood, and how this molecular framework permits the emergence of specific patterns of brain oscillations observed during mnemonic processing is unknown. Here, we directly compare intracranial electroencephalography recordings from the neocortex in individuals performing an episodic memory task with human gene expression from the same areas. We identify genes correlated with oscillatory memory effects across 6 frequency bands. These genes are enriched for autism-related genes and have preferential expression in neurons, in particular genes encoding synaptic proteins and ion channels, supporting the idea that the genes regulating voltage gradients are involved in the modulation of oscillatory patterns during successful memory encoding across brain areas. Memory-related genes are distinct from those correlated with other forms of cognitive processing and resting state fMRI. These data are the first to identify correlations between gene expression and active human brain states as well as provide a molecular window into memory encoding oscillations in the human brain.
