July – September 2019

The Department of Physiology is excited to welcome Dr. Daniel Denman to our Faculty!

The Denman Lab is interested in how populations of neurons generate sensory perceptions. We use quantitative psychophysics, in vivo electrophysiology, in vivo imaging, circuit tracing, and computational methods to study the dynamics of populations of single neurons. We particularly focus on how neural interactions - within areas and distributed widely across the mammalian brain – represent, transmit, and transform information along the way to generating a perception. The interactions we probe span timescales from behavioral epochs (minutes) to non-linear neural integration (microseconds).

Our lab focuses on the neural mechanisms of visual perception. We use primary visual cortex (V1) as an organizing hub, investigating the circuit interactions within V1 microcircuits as well as interactions of V1 neurons with connected cortical and subcortical areas. Using physiological circuit-tracing, we seek to understand not just how information can be shaped in visual circuits, but what aspects of neural activity are *actually* used to generate perceptions. Using circuit-guided simultaneous high-density electrophysiology, we generate hypotheses for how neural dynamics relate to perception. Optogenetic and electrical manipulations allow us to causally test these hypotheses, to the extent that causality is a useful framework for understanding any neural function.

April – June 2019

The Department of Physiology is excited to welcome Dr. Cristin Welle to our Faculty!

Dr. Cristin Welle, PhD, runs the BIOElectrics Lab, which focuses on the development and implementation of translational neurotechnology. The lab investigates the relationship between neurological medical devices and functional plasticity in the nervous system. Dr. Welle has a primary appointment in the Department of Neurosurgery, where she also has recently begun her role as the Vice-Chair for Research. Within the past quarter, Dr. Welle’s Good News this past quarter is that both the BIOElectrics lab and Dr. Welle’s office have been relocated to the 7th floor, and that she is joining the Dept. of Physiology and Biophysics. We are looking forward to being a part of the department!
