How Do We Know What We Know?
The long-term goal of our laboratory is to understand the molecular, cellular, circuit and behavioral mechanisms of how we know what we know (check out our researchmaps!).
Much of our work is focused on a crucial and exciting component of this question: memory. We are also leveraging our studies of memory and extraordinary cognition to develop treatments for cognitive disorders.
We are searching for the molecular, cellular and circuit processes that underlie the encoding, allocation, storage and linking of information in the brain.
Studies in our lab use state-of-the-art approaches such as optogenetics, circuit mapping, one and two-photon in vivo imaging, etc.
Insights into mechanisms of memory are being used to unravel the causes and develop treatments for cognitive deficits associated with aging, intellectual disabilities, and autism. Our studies in mice suggested that it is possible to reverse in adults neurodevelopmental disorders, such as intellectual disabilities associated with mutations in NF1, TSC and DISC1.
Studies of the mechanisms underlying extraordinary cognitive function are being used to develop general treatments for cognitive disorders and to accelerate recovery after brain injury.
The Silva laboratory is also developing bioinformatic strategies to address the growing complexity of the literature, including the development of a set of algorithms and a free web app (researchmaps.org) to track causal information in biology.
