Topic: mammalian retina

In this talk, I will focus on recent work that has uncovered the diversity of intrinsically photosensitive retinal ganglion cells (ipRGCs). These are a unique type of retinal ganglion cell that contains the photopigment melanopsin. ipRGCs are the retinal neurons responsible for driving non-imaging forming behaviors and reflexes, such as circadian entrainment and pupil constriction, amongst many others. My lab has recently focused on uncovering the diversity of ipRGCs, their distribution throughout the mammalian retina, and their axon projections in the brain.

As a developmental outpocket of the brain, the retina exhibits features commonly found in most brain areas, including neurovascular interactions. In this presentation I will discuss various pathways that contribute to neurovascular interactions in the mammalian retina and present newly uncovered elements that likely participate in these pathways. Information obtained from retina could improve our understanding of neurovascular coupling pathways throughout the brain.
