The Levitt Lab

Research in the Levitt Lab is focused on understanding the mechanisms underlying opioid-induced respiratory depression, which is the cause of death from opioid overdose. This is a timely problem given that the opioid epidemic accounts for nearly 50,000 deaths in the US annually and rising. It is also an interesting biological question, and our research will help us understand the circuitry that generates and controls breathing – one of our most fundamental behaviors. We use sophisticated electrophysiology approaches and in vivo measurements of breathing in combination with viral and genetic mouse models to target specific neuronal types.
