Dichotomous parvalbumin interneuron populations in dorsolateral and dorsomedial striatum.

Monteiro P, Barak B, Zhou Y, McRae R, Rodrigues D, Wickersham IR, Feng G. J Physiol. 2018 May 29. doi: 10.1113/JP275936. [Epub ahead of print] Dorsomedial striatum circuitry is involved in goal-directed actions or movements that upon repetition become habits, encoded by dorsolateral striatum. An inability to shift from habits can compromise action-control and prevent […]

The BRAIN Initiative Cell Census Consortium: Lessons Learned toward Generating a Comprehensive Brain Cell Atlas.

Ecker JR, Geschwind DH, Kriegstein AR, Ngai J, Osten P, Polioudakis D, Regev A, Sestan N, Wickersham IR, Zeng H. Neuron. 2017 Nov 1;96(3):542-557. A comprehensive characterization of neuronal cell types, their distributions, and patterns of connectivity is critical for understanding the properties of neural circuits and how they generate behaviors. Here we review the […]

A comprehensive understanding neuronal cell type diversity is an essential guide to selective manipulation and illuminating cell type specific functional contributions toward health and disease. Accordingly, the Brain Initiative Cell Census Network (BICCN) is unifying the efforts of laboratories with unique expertise in anatomy, genetics, electrophysiology, and function to classify neurons and create a common […]

Combining Optogenetics and Electrophysiology to Analyze Projection Neuron Circuits

Yamawaki N, Suter BA, Wickersham IR, Shepherd GM. Cold Spring Harb Protoc. 2016 Oct 3;2016(10) A set of methods is described for channelrhodopsin-2 (ChR2)-based synaptic circuit analysis that combines photostimulation of virally transfected presynaptic neurons’ axons with whole-cell electrophysiological recordings from retrogradely labeled postsynaptic neurons. The approach exploits the preserved photoexcitability of ChR2-expressing axons in […]

Massive normalization of olfactory bulb output in mice with a ‘monoclonal nose’

Roland B, Jordan R, Sosulski DL, Diodato A, Fukunaga I, Wickersham I, Franks KM, Schaefer AT, Fleischmann A. Elife 5. pii: e16335 (2016). Perturbations in neural circuits can provide mechanistic understanding of the neural correlates of behavior. In M71 transgenic mice with a “monoclonal nose”, glomerular input patterns in the olfactory bulb are massively perturbed […]

We will use high throughput techniques to produce a set of viral vectors that will allow selective expression of transgenes in specific populations of neurons in the brain. Along with many other applications, this will allow optogenetic control, recording, and genomic modification of targeted neuronal populations without the need for production of transgenic or knock-out […]
