Welcome to the Josselyn Frankland Lab
Neurobiology Laboratory at the Hospital for Sick Children

Research

Learning and Memory

Memory Allocation

How do neurons become allocated to a memory trace and how can we manipulate their activity to understand memory?

Remote Memory

How are remote memories organized in the cortex, and what the molecular and cellular events that underlie their consolidation?

Neurogenesis and Forgetting

What is the contribution of new neurons to hippocampal memory function. In particular we are interested in how new neurons regulate clearance of memories from the hippocampus (or forgetting).
