% % The purpose of this code is to inspect the sensitivity of the main % results due to changes in channel conductance, and time constants. % % 1. How is the frequency changed? % 2. How is the shunting changed? % 3. How is the synchronisation changed? % % To check this we run a genesis script which allows us to modify the % channel parameters. The model has four FS neurons, A1, A2, B1, B2. % % A1 and A2 are identical, but their channel parameters can be % modified (both neurons always have the same set of parameters) % B1 and B2 are identical. their channel parameters are at default values % A1 and B1 are coupled by gap junctions, A2 and B2 are uncoupled. % % Neuron number: A1 = #1, A2 = #2, B1 = #3, B2 = #4 % % clear all, format compact tic % Seed the random numbers by the clock randId = floor(sum(1e5*clock)); s = RandStream.create('mt19937ar','seed',randId); RandStream.setDefaultStream(s); FSpars = [1 1 1 1 1 1 1 1 1 1]; parFile = 'FSparameters.info'; outputFile = 'FSoutput'; % Random seed for FS input randSeed = floor(1e5*rand); maxTime = 2 %20; numCells = 4; corrRudolph = 0.5; upFreq = 4; noiseFreq = 0.11; allowVar = 1; % In this simulation we only use numCells/2 input sets, this is % because each connected neuron has an unconnected reference neuron. makeAllSynapticInput(corrRudolph, upFreq, noiseFreq, ... maxTime, allowVar, ... randSeed, numCells/2); % Indexes of MOD:ed cells, and of those with original channels cellModIdx = 1:2:numCells; cellOrigIdx = 2:2:numCells; % Generera FS morphologin channelMask = {}; % All identical cellVar = 0; lenVar = 0; % First parameter is index of neurons to write p-file for makeFSMorphMOD(cellModIdx, cellVar, channelMask, lenVar) makeFSMorph(cellOrigIdx, cellVar, channelMask, lenVar) % Gap junction info gapSource = {'/fs[0]/primdend1'}; gapDest = {'/fs[2]/primdend1'}; gapRes = 2e9; % 0.5nS writeFSMODinfo(parFile, outputFile, maxTime, numCells, ... gapSource, gapDest, gapRes, ...
