The AttractorNetwork folder contains code to solve mean the field equations of an attractor neural network, in which correlated patterns are stored. The code is written in Julialang. In the sub-folder "Plots", you can find some python files to plot the result of the main code. In order to reproduce the results of the paper and plot them follow the instruction below. ---------------------------------------------------------------------------------- PART 1 - INITIALISATION: ---------------------------------------------------------------------------------- The code is written in julialang (tested with version Julia-1.4) and Python (tested with version 3.7.0) -Download the AttractorNetwork folder from : .... !!!!!!!!!!! +Download the AttractorNetwork folder from : https://c4science.ch/source/pub_Gastaldi_2021_AttractorNetwork.git In the folder you will find - the "Main.jl" file, - the "Plots" folder which contains the plot scripts in Python - the "src" folder which contains the "AttractorNetwork.jl" file. - the "Data_analysis" folder - the "Files" folder The following empty folders should also be present in the AttractorNetwork folder. a. Output folders: - Output_1pop - Output_2pop - Output_3pop - Output_4pop - Output_2pop_adapt - Output_4pop_adapt - Output_full_sim - Output_full_sim_adapt - Output_full_sim_distr_gains - Output_full_sim_adapt_distr_gains b. Figures folders: - Figures_1pop - Figures_2pop - Figures_3pop - Figures_4pop - Figures_2pop_adapt - Figures_4pop_adapt - Figures_full_sim - Figures_full_sim_adapt - Figures_full_sim_distr_gains - Figures_full_sim_adapt_distr_gains - Figures_exp IN SHORT: The output folders will host the .dat files that are outputted by running the Main.jl script. The same data files are read by the plot scripts contained in the "Plots" folder. Running the plots scripts creates images files in the corresponding Figures folders. Details are given below. ---------------------------------------------------------------------------------- PART 2 - USING THE CODE: ---------------------------------------------------------------------------------- Open the file "Main.jl" and uncomment the function you want to run. Open Julia in your terminal and run the "Main.jl" file doing: import("Main.jl") The following operations are executed: - activation of the package AttractorNetwork, - importation of the module AttractorNetwork.jl contained in the "src" sub-folder - definition of the used model: you can choose between TwoPopulations.MeanField() and TwoPopulations.MFnoSelfInteraction(), this will be relevant only if you run a function from the module TwoPopolations. The model TwoPopulations.MeanField() used a standard mean field for two correlated memory patters, while the model TwoPopulations.MFnoSelfInteraction() uses the mean field theory in which self interaction is excluded, this requires the an extra correction as described in the Methods session. WARNING: the model TwoPopulations.MFnoSelfInteraction() requires to solve the mean-field equation recursively. This means that solving the system with this model requires a long computational time and it is recommended to run the computation in parallel. For example, if you want to use 4 cores on your machine, you can run the command: import("Main.jl") -p 4 - running the uncommented function. -- LIST OF THE 21 FUNCTIONS IN THE Main.jl SCRIPT AND WHAT THEY DO -- In the following we use a # character at the place of the parameters' values. #################################################################### ################# MEAN FIELD ####################################### #################################################################### -- LIST OF PARAMETERS -- gamma = sparseness of the memory representation resolution = resolution of the grid search in Eq. 108, 110 of the paper factor = resolution factor named correction-constant in Eq. 107, 109 size = how many values of C_hat (or alpha) do you want to consider in building the bifurcation plot rm = maximal firing rate, r_{max} in the paper A = connection strength in the definition of the weight matrix h0 = firing rate threshold b = steepness of the gain function, see Eq. 9 load = network load = alpha = P/N I1 = intensity of the external current given to population 1 I2 = intensity of the external current given to population 2 bound_low = lower bound of the grid search, compare to Eq. 110 bound_up = upper bound of the grid search, compare to Eq. 110 bound_r = upper bound of the R variable, max(R) in Eq. 108 C_hat = correlation between patterns, corresponding to the parameter C defined in Eq. 41. NOTE: C_hat is the correlation coefficient C, not the fraction of shared neurons c. The relation between the two quantities is c = C(1 − γ) + γ mod = you can choose one of the following model, which correspond to mean field with or without self interaction (see section "Excluding self-interaction" in the paper): TwoPopulations.MeanField() or TwoPopulations.MFnoSelfInteraction() corr_noise = boolean variable, choose true if you want to have correlated background patterns of false if you want background patterns to be independent. Refer to section "Overlapping background patterns" in the paper. time_step = time step in the Euler integration of a dynamical equation ------------------ ONE POPULATION ------------------------------ The following scripts are need to solve the mean field theory for one homogeneous neural population only.

Inside the "Data_analysis" folder, you find a "Data" folder that containes the original experimental data files. Inside this folder, you find the scripts: - Check_prob_distr_correlation_and_sum_equal_1.py: it is a numerical check that the probability distributions of Eq. 99 actually sum up to 1 - Compare_theory_probs_and_DeFalco2016.py: it plots the figures "mean_of_sessions_gamma#_c#.pdf" and the previous ones in the folder "Data_analysis/Figures" it reproduces theoretical predictions in Fig. S6 and the distribution of experimental data. The plots the theoretical predictions in Fig. S6 and "Data_number_of_concepts_a_neu_responds_to_all_pyramidal_and_interneus" will be found in the folder "Data_analysis/Figures" NOTE: the data vector defined into the script has been given by Emanuela De Falco and Rodrigo Q. Quiroga and contains the data points in fig. 6 and fig.S6. There are 2 versions of such a vector in the code, corresponding to a smaller and a bigger database. - extract_gamma_and_c_from_DeFalco2016.py: it prints the extracted values of c and gamma to the screen 21. AttractorNetwork.Reproduce_experiment(): it reproduces fig 6. and S6.: it runs a number 'trials' of virtual experiments with the chose number of neurons, find mean and std. It outputs in the "Files" folder the following files - strict_how_many_neurons_respond_to_how_many_concepts_N#_trials#.dat - random_how_many_neurons_respond_to_how_many_concepts_N#_trials#.dat - parent_how_many_neurons_respond_to_how_many_concepts_N#_trials#.dat - ind_how_many_neurons_respond_to_how_many_concepts_N#_trials#.dat DEFAULT PARAMETERS: γ = 0.002, c_hat = 0.04, N = 1000, n_repetitions = 8 To plot the results of this function - go to the "Plots" folder - open the plotting script "PLOT_experiment_mean_and_std_groups_recalled.py" and make sure that the parameters at the beginning of the file are specified correctly. - run the plotting script "PLOT_experiment_mean_and_std_groups_recalled.py" - the file "Final_fig_N#_trials#.pdf" will appear in the folder "Figures_exp". FINAL NOTES: --- TwoPopAdapt --- The maximal firing rate is assumed to be the same for all homogeneous populations {11}, {10}, {01}, {00} and g11.rm is the parameter used as a reference in the code. --- Full simulation modules --- There are two functions to generate correlated binary patterns: "generate_binary_patterns_fix_sparseness(p)" and "generate_binary_patterns(p)". The figures in the paper are generated with fixed sparsity, and in this the function that is used in "evolve(...)", however it can substituted manually. The alternative function "generate_binary_patterns" is already in place and commented at the moment. The two modules of full simulation with distributed gains (with and without adaptation) allow a distribution of the gain function parameters across neurons and they don't have a corresponding mean-field module. --- All modules with adaptation --- The periodic global inhibition is defined as a Sinusoidal wave (as in the paper). An alternative square wave version can be chosen manually by uncommenting it and comment the sinusoidal version.
