  • Neural circuit assembly and visual processing in the retina

Research Abstract:

We would like to understand the principles that guide the assembly of neural circuits and to decipher the way they process information. Our lab focuses on the mammalian retina. We use transgenic and ballistic gene delivery to fluorescently label specific neurons and connections in this circuit, and follow their development using confocal and multi-photon imaging. In addition, we use light - the natural input to this circuit - to elicit signals and track the processing of visual information among successive neurons of the circuitry using patch-clamp and multi-electrode array recordings. By combining these approaches, we hope to identify features of the retinal circuit architecture that perform particular computations and characterize how they arise during development. We will then probe underlying mechanisms of circuit assembly and function through genetically targeted manipulations of specific cells in the retina.
