Alexander Fleischmann, PhD

Department of Neuroscience, Brown University

My laboratory is interested in how neural circuits generate sensory perception and behavior. We use a combination of molecular genetic, in vivo imaging, computational and behavioral approaches to determine fundamental functional properties of neural networks in the mouse olfactory cortex. I have joined the Brown Neuroscience Department in January 2018.
