Sepideh Keshavarzi studies how visual and vestibular signals are combined in the cortex for perception of motion and spatial orientation. Her research is particularly focused on neural circuits engaging the retrosplenial and visual cortices. She uses two photon calcium imaging and electrophysiological techniques to record activity of cortical neurons in head fixed and freely moving mice. She is also investigating the functional properties of these neurons in context of their input connectivity using viral tracing and whole brain imaging. The findings of her research will help better understand the sensory function of cortical circuits and their role in spatial navigation.
