The Spike Histogram Module for Windows provides the neuroscientist, in conjunction with our PowerLab systems, the ability to record and
analyze extracellular spike data in real time and offline.
The Spike Histogram Module should be used with the latest version of LabChart. Click here for the latest LabChart update for
Windows.
This module provides the user with the ability to discriminate and analyze extracellular neural spike activity, featuring a simple
height/width discriminator. The height and width discriminator window provides reliable discrimination against unwanted units in multi-unit
recordings. This method of detection is better than simple amplitude window discrimination and faster than template matching. The module
provides both in real time and offline discrimination and analysis, and at all times the recorded spikes can be reanalyzed with modified discriminator settings.
Discriminator window – spike populations are selected in the left-hand pane, with
selected spikes viewed on the right-hand pane (red lines).The Discriminator Settings window can be accessed from the Discriminator window and user defined spike detection settings of noise threshold
(V) and waveform period (secs) allow for automated detection of spikes and filtering of unwanted units.
The Spike Histogram Module also features four histogram windows which can display Ratemeter, Amplitude, Interspike Interval and Peristimulus
Time Histograms. The chart file and analysis windows can be viewed simultaneously and operate both offline and in real time, with the option of all data collected
by the spike detection parameters being updated and logged into the analysis windows in real time.
NeuroExplorer
Another added feature to the Spike Histogram Module is the ability to export to NeuroExplorer software
for advanced analysis of spike trains. The export feature saves files in .nex format which are effortlessly opened in NeuroExplorer. NeuroExplorer
provides an extensive set of spike train analysis options and histograms including autocorrelograms, crosscorrelograms, burst analysis, spectral
analysis, Poincare maps. For a complete list of features see our Product page. NeuroExplorer also includes features for analysis of continuously
recorded signals and populations of neurons as well as allowing the user to create publication-quality figures. A built-in scripting engine
allows data editing as well as the ability to run analyses in batch mode to automate analysis tasks. NeuroExplorer can be purchased independently
or as a module with Spike Histogram, see details below.
NeuroExplorer – a selection of analyses of a spike train (autocorrelogram, Interspike
Interval, Power Spectral Density and Joint PSTH)See the NeuroExplorer page for more details.
