Database Analysis of Simulated and Recorded Electrophysiological Datasets with PANDORA’s Toolbox

Abstract

Neuronal recordings and computer simulations produce ever growing amounts of data, impeding conventional analysis methods from keeping pace. Such large datasets can be automatically analyzed by taking advantage of the well-established relational database paradigm. Raw electrophysiology data can be entered into a database by extracting its interesting characteristics (e.g., firing rate). Compared to storing the raw data directly, this database representation is several orders of magnitude higher efficient in storage space and processing time. Using two large electrophysiology recording and simulation datasets, we demonstrate that the database can be queried, transformed and analyzed. This process is relatively simple and easy to learn because it takes place entirely in Matlab, using our database analysis toolbox, PANDORA. It is capable of acquiring data from common recording and simulation platforms and exchanging data with external database engines and other analysis toolboxes, which make analysis simpler and highly interoperable. PANDORA is available to be freely used and modified because it is open-source (http://software.incf.org/software/pandora/home).

The Virtual Brain Integrates Computational Modeling and Multimodal Neuroimaging

“…When fitting new timeseries, instead of re-estimating the parameters for a dynamic regime that might have been inferred before, a dictionary search is conducted, and observed dynamics are related to probable parameter settings. The idea of generating simulation databases was previously successfully applied to several neuroscience models (Calin-Jageman et al, 2007;Doloc-Mihu and Calabrese, 2011;Gü nay et al, 2008Gü nay et al, , 2009Gü nay and Prinz, 2010;Lytton and Omurtag, 2007;Prinz et al, 2003).…”

CyberRat Probes: High-Resolution Biohybrid Devices for Probing the Brain

“…Over the years academic and commercial software tools and/or packages are developed to process and analyze neuronal data [30], [31], [32], [33], [34], [35], [36], [37], [38], [39], [40]. They mainly deal with data visualization, spike detection and sorting, spike train analysis, and EEG analysis.…”

Biological Databases for Behavioral Neurobiology

“…As a result, many life science databases in general and behavioral neuroscience databases in particular have grown out of a single research lab to mediate a particular tactical need. For example, neuroscience databases and data management tools include those seeking to manage transcriptional data (Shepherd et al, 1998), complex images such as fMRI scans (Marcus et al, 2007), laboratory information management systems (LIMS) and data management (Baker, Galloway, Jackson, Schmoyer, & Snoddy, 2004), formal collaborations and federated repositories (Gardner et al, 2008), publication data (Ruttenberg, Rees, Samwald, & Marshall, 2009), protein interaction (Colland et al, 2004; Shoemaker et al, 2012) and mass spec data (Horai et al, 2010), behavioral data (Maddatu, Grubb, Bult, & Bogue, 2012), electrophysiological measurements (Günay et al, 2009), and a series of disorder related repositories (Goodman et al, 2003; Matuszek & Talebizadeh, 2009). While not necessarily in conflict with the strategic goals of the greater behavioral neuroscience community, the ad hoc collection of boutique databases, analysis tools and information repositories that exist on the local level are often incompatible with comprehensive data mining.…”
