NeuroExplorer - neurophysiological data analysis

• Model# MLS063

Overview:

NeuroExplorer is a sophisticated neurophysiological data analysis package which provides the user with a large number of analysis features.

The new Spike Histogram module for Windows has the Export to NeuroExplorer feature, which exports data files in a .nex format for association with NeuroExplorer. A Demo version of the software can be downloaded from www.neuroexplorer.com.

The following is a complete list of the many features and functions of NeuroExplorer.  

Spike Train Analyses Features:

Interspike interval histograms Rate histograms Perievent histograms Perievent rasters Autocorrelograms Crosscorrelograms with shift-predictors Joint peristimulus histograms Burst analysis Spectral densities

Perievent histograms versus time Place cell analysis Reverse correlations Cumulative activity Instantaneous frequency Interspike intervals versus time Poincare maps of interspike intervals Regularity analysis

Analysis of continuously recorded signals: Correlations between spike trains and continuous signals Spike-triggered average Spike-triggered rasters Spectral analysis

Analysis of populations of neurons: Principal component analysis 3D network activity animation Population PST histograms

Data Importation:
The Spike Histogram Module allows data to be easily saved and imported into NeuroExplorer for further analysis. Data can also be imported into NeuroExplorer from a number of formats including text, Excel and MATLAB files.

Graphics Features:
NeuroExplorer creates fully editable publication-quality figures:

2D and 3D black-and-white and color graphs Unlimited number of graphs per figure Tables of graphs. Example: all pairwise correlations within a group of neurons. Completely customizable figure elements: colors, fonts, tick sizes, etc. Unlimited custom graphics elements: lines, arrows, boxes, text labels Single-page and multi-page printing Export of graphics to other applications via the clipboard or Windows metafiles

Numerical Tables:
Two numerical results tables (Results and Summary) are produced for every analysis. The Results table contains:

Bin location Bin counts/frequencies/probabilities Shift-predictor values and confidence limits for crosscorrelogram analyses Joint PST matrix for Joint PSTH analysis Other analysis-specific results

The Summary table contains:

• The number of spikes used in analysis
• Minimum, maximum, mean, standard deviation and standard error of mean of the histogram
• Expected values and the confidence limits for the PST and crosscorrelogram analyses
• Other analysis-specific statistics

All the numerical results or the Summary table can be transferred to Excel or MATLAB.

Trial-Based Data Analysis
NeuroExplorer provides extensive support for the analysis of the trial-based experiments:

• Trials of variable duration are supported
• Trials can be selected using the trial list
• Trials can be tagged according to various criteria. Example: tag the trials that contain the correct response.
• Analysis can be performed using all the data or only the data from the specified trial set.
• Several trial sets can be used in one analysis. Example: calculate the crosscorrelograms for the correct-response trials and the incorrect-response trials and display them side-by-side.

Internal Scripting
A powerful built-in scripting language allows you to automate many analysis tasks:

Open and close data files Select data for analysis Specify analysis parameters Specify graphics options Apply analysis templates Save results as a text file Send data and results to Excel Send data and results to Matlab Execute Matlab scripts Modify existing spike trains and other data Create new events and spike trains Read and write text files

Working With Other Applications
NeuroExplorer is designed as an open analysis environment. You can use other programs to extend the capabilities of NeuroExplorer :

• Copy data to Excel, edit the data in Excel and paste it back to NeuroExplorer
• Generate data in Matlab and transfer it to NeuroExplorer
• Copy numerical results to Excel or Matlab for post-hoc analysis
• Execute Matlab scripts from NeuroExplorer to do the post-processing
• Control NeuroExplorer from any application that supports ActiveX interface
