The Spike Train Analysis toolbox is the third of four NeuroMAX
Toolboxes, which also include Spike Detection, Spike Sorting,
and Display Tools. After detecting individual spikes (with
the Spike Detection toolbox), and sorting the spikes into
units (with the Spike Sorting tools), you can analyze the
spike times of specific units with the Spike Train Analysis
tools.
The various Spike Train Analysis tools are summarized below.
Select a specific tool for a complete description of its
strengths in analyzing spike train data.
StationarityTest (Under Development):
Stationarity is the fundamental assumption behind all of
the point process analyses found in the Spike Train Analysis
toolbox. Refer to this tool for details. (A point process
is a random collection of points, where each point represents
the time and location of an event.)
ConditionalMean (Under Development): Examines
whether or not the inter-event intervals have a first order
dependence structure.
Hazard (Under Development): Gives the
value of the interval histogram divided by the sum of the
interval histogram * the binwidth at each bin.
IntervalHist: Estimates the probability
density function of inter-event interval durations.
PSTHist (Under Development): Creates a
Post Stimulus Time histogram for data collected with a repeated
stimulus.
FitPoisson: Fits a Poisson1 mode to each unit’s event times.
GeneratePoisson: Generates spike times
based on a Poisson1 model.
CreateSimulation (Under Development):
Creates a simulated data set based on a specific data sample,
using the available information about a data set (noise
samples or models, identified unit spike waveform templates,
and unit firing characteristics) to generate a simulated
data set that closely resembles a specific data set.
1 A discrete probability distribution that expresses
the probability of a number of events occurring in a fixed
period of time if these events occur with a known average
rate, and are independent of the time since the last event.
