Alcino Silva

The Silva laboratory is studying the molecular, cellular and circuit processes that underlie the allocation, encoding, storage and linking of memories. To accomplish this they are using a variety of techniques including sophisticated molecular genetic approaches, optical physiology, optogenetics, in vivo 2 photon imaging, a new generation of head-mounted fluorescent miniscopes and behavioral analyses.

Silva and colleagues are also studiying the impact of these mechanisms in animal models of cognitive disorders, including intellectual disabilities. Based on these mechanistic studies, they have developed treatments for Noonan Syndrome, age-related cognitive decline, Neurofibromatosis type I, Tuberous Sclerosis, and cognitive deficits associated with HIV. The Silva laboratory is also developing approaches to accelerate recovery after brain injury and bioinformatic strategies for tracking and planning experiments (
