4.4. Activity Animation Parameters
Animation Template - allows you to choose the Animation Template. When you start using 3D
Module, only one Animation Template, Default is available. You can add templates by saving any set
of Animation parameters as a new template (to do this, use 3DView | Save As New Animation
Template menu command).
Reference - if this parameter is None, NeuroExplorer shows the rate histograms-based animation
(that is, neuronal activity in real time). If this parameter is not None, NeuroExplorer calculates the
perievent histograms for the specified reference and shows neural network activity around the
specified event.
NeuroExplorer uses a sliding window to calculate the firing rates of the neurons. The window has the
width equal to the Bin. The first window begins at Start time. The second window begins at
Start+Shift and ends at Start+Shift+Bin, etc. For each of the windows, the number of spikes that
each neuron has inside this window is calculated. Then for each neuron the point (X_position,
Y_position, Spike_Count) is shown in a 3D graph.
Start - beginning of the first sliding window.
Bin - width of the sliding window.
Shift - sliding window shift.
Number of shifts - number of windows (frames).
Time Smooth - allows you to enable or disable time smoothing of the spike counts.
Time Smooth Width - sigma of the Gaussian filter used for smoothing over time. See
Post-
Processing Options for more information about smoothing the histograms.
Matrix NX - the number of points in the mesh in X direction.
Matrix NY - the number of points in the mesh in Y direction.
Neuron Size - the size of the square (in mesh points) that represents a single neuron.
Loop - an option to show the animation in a "loop" mode (after all the frames are shown, animation
goes back to the first frame and starts again).
