Software tool for data sharing, incorporating blogs and spatial registration of data. Mainly used in geological data sets. A Virtual Research Environment (VRE) aims to combine the capabilities of two existing technologies that have already seen wide adoption among scientists: - The Godiva2 data visualization system provides a means for scientists to browse interactively in a ''Google Maps-like'' fashion through large environmental datasets, including numerical model outputs and high-resolution satellite imagery, using only a web browser. - The LabBlog is a web-based blogging tool specifically designed for the practising scientist to record, disseminate and evaluate their research. The Blog can also be used as a collaboration tool that allows secure discussion between colleagues. Although initially designed for the use of laboratory chemists, the LabBlog is being adapted in this project to meet the needs of environmental scientists. The BlogMyData VRE will allow scientists to explore data visually using Godiva2, then make comments about features in the data on a blog. Colleagues will discover these blog entries and offer further information, providing answers to research questions through comments. Through RSS and GeoRSS feeds, colleagues, investigators and other interested parties can be notified of research activity, and scientists can discover hitherto-unknown colleagues working with similar data in similar geographic regions. Sponsors: BlogMyData is a collaboration between the Reading e-Science Centre and the University of Southampton and is one of the JISC VRERI projects.

The data sets included in this resource are published in Kravitz et al, 2012 Distinct roles for direct and indirect pathway striatal neurons in reinforcement (Nat. Neurosci). The data shows: optogenetic activation of dopamine D1 or D2 receptor-expressing striatal projection neurons influenced reinforcement learning in mice. Stimulating D1 receptor-expressing neurons induced persistent reinforcement, whereas stimulating D2 receptor-expressing neurons induced transient punishment. These 3 recording files contain data collected in 2010 and 2011 by Lex Kravitz in Anatol Kreitzer''s lab at the Gladstone Institutes. Each file contains ~ 1 hour of awake in vivo recording data, containing the spike times for ~30 minutes of spontaneous activity, preceeded or followed by 400 laser pulses (473nm laser light, 1 sec pulses, 3 seconds inter-pulse-interval). The laser pulses were presented at 4 intensities: 0.1mW, 0.3mW, 1.0mW, and 3.0mW, and pulse times at each intensity are given in separate columns in each data file. Finally, each data file contains the identification of ''light-modulated units'' as we identified them (see methods below). Methods: Viral expression of DIO-ChR2-YFP and DIO-YFP We used double-floxed inverted (DIO) constructs to express ChR2-YFP fusions and YFP alone in Cre-expressing neurons, which virtually eliminates recombination in cells that do not express Cre-recombinase (Sohal et al, Nature, 2009). The double-floxed reverse ChR2-YFP or YFP cassette was cloned into a modified version of the pAAV2-MCS vector (Stratagene, La Jolla, CA) carrying the EF-1a promoter and the Woodchuck hepatitis virus posttranscriptional regulatory element (WPRE) to enhance expression. The recombinant AAV vectors were serotyped with AAV1 coat proteins and packaged by the viral vector core at the University of North Carolina. The final viral concentration was 4 x 10^12 virus molecules/mL (by Dot Blot, UNC vector core). This viral construct can now be ordered in single aliquots directly from UNC Vector core as product AAV-EF1a-DIO-hChR2(H134R)-EYFP, at http://genetherapy.unc.edu/services.htm) Implantation of electrode arrays for awake recordings Anaesthesia was induced with a mixture of ketamine and xylazine (100mg ketamine plus 5mg xylazine per kilogram of body weight i.p.) and maintained with isoflurane through a nose cone mounted on a stereotaxic apparatus (Kopf Instruments). The scalp was opened and a hole was drilled in the skull (0.0 to +1.0mm AP, -1.0 to -2.0mm ML from bregma). Two skull screws were implanted in the opposing hemisphere. Dental adhesive (C&B Metabond, Parkell) was used to fix the skull screws in place and coat the surface of the skull. An array of 16 or 32 microwires (35-��m tungsten wires, 100-��m spacing between wires, 200-��m spacing between rows; Innovative Physiology) and one optical fiber in a ferrule was lowered into the striatum (3.0mm below the surface of the brain) and cemented in place with dental acrylic (Ortho-Jet, Lang Dental). After the cement dried, the scalp was sutured shut. Animals were allowed to recover for at least seven days before striatal recordings were made. In vivo electrophysiology Voltage signals from each recording site on the microwire array were band-pass-filtered, such that activity between 150 and 8,000Hz was analysed as spiking activity. This data was amplified, processed and digitally captured using commercial hardware and software (Plexon). Single units were discriminated with principal component analysis (OFFLINE SORTER, Plexon). Two criteria were used to ensure quality of recorded units: (1) recorded units smaller than 100��V (~3 times the noise band) were excluded from further analysis and (2) recorded units in which more than 1% of interspike intervals were shorter than 2ms were excluded from further analysis. Average waveforms were exported with OFFLINE SORTER. During the recording we coupled the array to a laser and pulsed the laser at four intensities (0.1mW, 0.3mW, 1mW, and 3mW). Laser stimulation was run in a cyclical fashion, on for 1 second, and off for 3 seconds. Each neuron received 100 pulses at each laser intensity. Identification of ChR2 expressing units in in vivo recordings For all neurons, peri-event histograms were generated for each laser intensity independently. Neurons were classified as ChR2-expressing if they exhibited a firing rate greater than 3x above the standard deviation of the 1-second preceding the laser pulse within 10msec of the laser onset. Each neuron was tested independently at each laser power, and neurons that satisfied this criteria at any one power were defined as ChR2-expression.

Laser tool that enables neurons to be optically silenced by pulses of yellow light, the light-activated chloride pump halorhodopsin (Halo), in a paper entitled Multiple-color optical activation, silencing, and desynchronization of neural activity, with single-spike temporal resolution. Temporally precise, noninvasive control of activity in well-defined neuronal populations is a long-sought goal of systems neuroscience. We adapted for this purpose the naturally occurring algal protein Channelrhodopsin-2, a rapidly gated light-sensitive cation channel, by using lentiviral gene delivery in combination with high-speed optical switching to photostimulate mammalian neurons. We demonstrate reliable, millisecond-timescale control of neuronal spiking, as well as control of excitatory and inhibitory synaptic transmission. This technology allows the use of light to alter neural processing at the level of single spikes and synaptic events, yielding a widely applicable tool for neuroscientists and biomedical engineers. The quest to determine how precise neural activity patterns mediate computation, behavior, and pathology would be greatly aided by a set of tools for reliably activating and inactivating genetically targeted neurons, in a temporally precise and rapidly reversible fashion. Having earlier adapted a light-activated cation channel, 1channelrhodopsin-2 (ChR2), for allowing neurons to be stimulated by blue light, we searched for a complementary tool that would enable optical neuronal inhibition, driven by light of a second color. Here we report that targeting the 1codon-optimized form of the light-driven chloride pump halorhodopsin from the archaebacterium Natronomas pharaonis (hereafter abbreviated Halo) to genetically-specified neurons enables them to be silenced reliably, and reversibly, by millisecond-timescale pulses of yellow light. We show that trains of yellow and blue light pulses can drive high-fidelity sequences of hyperpolarizations and depolarizations in neurons simultaneously expressing yellow light-driven Halo and blue light-driven ChR2, allowing for the first time manipulations of neural synchrony without perturbation of other parameters such as spiking rates. The Halo/ChR2 system thus constitutes a powerful toolbox for multichannel photoinhibition and photostimulation of virally or transgenically targeted neural circuits without need for exogenous chemicals, enabling systematic analysis and engineering of the brain, and quantitative bioengineering of excitable cells.
