Title A sample program of the spectral timing model.
Free Keywords
Description Creative Commons AttributionThis is our re-implementation of the cerebellar model presented in the
following papers:

Daniel Bullock, John C. Fiala, and Stephen Grossberg (1994).
A Neural Network Model of Timed Response Learning in the
Cerebellum. Neural Networks 7(6/7) 1101--1114.

One can set parameters arbitrarily and simulate the network dynamics.

Please notice that this program is independent of the original version
developed by Bullock, Fiala and Grossberg (1994).

** Files

This folder contains the following files:

readme.txt :: This file

Makefile :: Makefile

mt19937ar-cok.c :: Mersenne Twister random number generator
http://www.math.sci.hiroshima-u.ac.jp/~m-mat/MT/emt.html

spectral_timing.c :: The source code written in C.

p.dat :: Plot of p values (activity of the model Purkinje cell).
Point (x,y,z) in each line represents the trial number, the time
from the CS onset, and the value of p.

q.dat :: Plot of q values (activity of the model nuclear cell).
Point (x,y,z) in each line represents the trial number, the time
from the CS onset, and the value of q.

spectra.dat :: Plot of spectra, f(x_{j}) in Eq.(3). The 1st column
represents time, the 2nd to N+1th columns the values of f(x_{j})
for j=0, ... , N-1, where N = 100 (100 spectra).

p.dat, q.dat and spectra.dat files are generated by the program.

** Usage

1. CS and US onsets (CS and C in p. 1110) can be set in the while loop
of the procedure 'run_single_trial'.
2. Other parameters written in p. 1110 also can be set at the beginning
of the code.
3. Compile the code.
4. Run the program.
5. The program generates p.dat, q.dat, and spectra.dat.

** Tips for plotting data

If you use gnuplot (http://gnuplot.info/), you can plot p.dat (q.dat)
in 3D using 'splot' command:

gnuplot> splot 'p.dat' with dots

X,Y,Z-axes represent the trial number, the time, and the value of p,
respectively. You will observe the timed decrease of the value of p
around 0.5s.

If the version of the gnuplot you use is 4 or higher, try the following:

gnuplot> set pm3d
gnuplot> splot 'p.dat' with pm3d

This looks much beautiful.
