NeuroExplorer

Analytical functions and plots

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

• Epoch counts
• Coherence analysis

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.

Repeated measures trials

• 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
