September 2014 - April 2019
Multiterabyte electron microscopy image volumes containing the neuronal circuits of interest are generated using high-throughput electron microscopy of serial thin sections. The arbors of selected neurons and the synaptic connections between them are then mapped, and the resulting 'wiring diagram' is analyzed in the context of circuit function.

The pathways of information flow and the properties of neurons and glia constrain the computational capabilities of the nervous system. In our lab, we are mapping the wiring diagram, with synaptic resolution, of the complete nervous system of the larval Drosophila. And, in the context of known circuitry, we study the neural basis of behavior using electrophysiology, optogenetics and modeling.

July 2006 - June 2015
Genome sequences are now known for thousands of different species. We are at a remarkable time in biology where at last we can look at the "source code" for life—the DNA sequences that specify development, regulation, and function of organisms—but we are still far from adequately understanding how to read this vast trove of encoded information or being able to reconstruct how it evolved.

February 2011 - January 2018
We develop optical methods for in vivo imaging and apply these methods to structural and functional studies of neural circuits.
November 2016 - May 2018
The lab will focus on automated reconstruction and identification of neurons in EM and light microscopic image data of the fly brain, where the goal is to exploit prior knowledge about global neuron shapes. This will enable biologists to find specific neurons of interest efficiently in huge EM volumes. Furthermore, it will be exciting to map circuits known from EM onto functional acquisitions to be able to observe known circuits in action. Therefore, the respective specific cell bodies have to be identified in functional imaging data.
September 2006 - August 2013
How does an organism compute its behavior? The Kerr lab seeks to answer this question for one of the simplest model organisms, the nematode worm Caenorhabditis elegans.
August 2006 - July 2018
Our ultimate goal is to provide a mechanistic understanding of a behaviorally relevant brain function.
To this end we are attempting to produce biophysically based explanations of the information-processing and storage capabilities of single and small networks of neurons. We use a variety of optical (two-photon transmitter uncaging, single and two-photon ChR2/NpHR activation, two photon Ca2+ imaging) and electrical (dual whole-cell recordings, cell-attached and outside-out patches) techniques in the various projects.
September 2016 - April 2018
Simultaneous advances in biochemical techniques and computing power in the early 21st century have transformed the field of biology by allowing for the generation of comprehensive large-scale molecular datasets. At Janelia, we will characterize cell types in the brain using transcriptome-wide data from single cells and small populations of cells to uncover the molecular grammar underlying the components of the nervous system and their connections. Ultimately, linking gene expression and epigenetic information to other phenotypes – including lineage, neuronal connectivity, and cell-cell communication – is crucial to understanding the control of neuronal identity.
September 2009 - August 2015
Determining the properties and salience of sensory cues is fundamental to the survival and characteristic behavior of most, if not all, organisms.

And 2) how is information relevant to animal behavior extracted by the brain? In short, we want to know what the mouse’s nose tells its brain.
