Genetically encoded calcium indicators (GECIs) are powerful tools for systems neuroscience. Recent efforts in protein engineering have significantly increased the performance of GECIs. The state-of-the art single-wavelength GECI, GCaMP3, has been deployed a number model organisms and can reliably detect three or more action potentials short bursts several vivo . Through structure determination, targeted mutagenesis, high-throughput screening, battery vitro assays, we dynamic range GCaMP3 by...

A major goal of the BRAIN Initiative is development technologies to monitor neuronal network activity during active information processing. Toward this goal, genetically encoded calcium indicator proteins have become widely used for reporting in preparations ranging from invertebrates awake mammals. However, slow response times, narrow sensitivity range Ca2+ and some cases, poor signal-to-noise ratio still limit their usefulness. Here, we review recent improvements field neural...

Abstract Understanding how cortical circuits generate complex behavior requires investigating the cell types that comprise them. Functional differences across pyramidal neuron (PyN) have been observed within areas, but it is not known whether these local extend throughout cortex, nor additional emerge when larger-scale dynamics are considered. We used genetic and retrograde labeling to target tract, intratelencephalic corticostriatal projection neurons measured their cortex-wide activity....

Abstract Motivation Targeted enrichment via capture probes, also known as baits, is a promising complementary procedure for next-generation sequencing methods. This technique employs short biotinylated oligonucleotide probes that hybridize with genetic material in sample. Following hybridization, the target fragments can be easily isolated and processed minimal contamination from irrelevant material. Designing an efficient set of baits sequences, however, NP-hard problem. Results We develop...

Functional differences across pyramidal neuron (PyN) have been observed within areas, but it is not known whether these local extend throughout cortex, nor additional emerge when larger-scale dynamics are considered. We used genetic and retrograde labeling to target tract (PT), intratelencephalic (IT) corticostriatal projection neurons measured their cortex-wide...

Motivation: Precise and personalized targeting for MR-guided focused ultrasound (MRgFUS) is desired to ensure treatment efficacy avoid side effect. Goal(s): To assess THalamus Optimized Multi Atlas Segmentation (THOMAS) on white-matter nulled MRI of the ventral intermediate (VIM) thalamic nucleus in MRgFUS tremor patients. Approach: We retrospectively assessed relationships standard indirectly targeted coordinates, post-FUS lesions, THOMAS segmentation with effects scores patients who...

Measurements of neuronal activity across brain areas are important for understanding the neural correlates cognitive and motor processes like attention, decision-making, action selection. However, techniques that allow cellular resolution measurements expensive require a high degree technical expertise, which limits their broad use. Widefield imaging genetically encoded indicators is throughput, cost effective, flexible approach to measure specific cell populations with temporal cortex-wide...
