Code for Figures in: Porrill & Dean: Sylent synapses, LTP and the indirect PF pathway ... Each folder contains MatLab code for 1 figure e.g. fig3data.m: file to generate data and basic plot fig3plot.m: file to read data and plot manuscript figure Fig3 also contains code fig3alt.m with i) real time implementation rather than batch ii) noisy rather than constant head velocity iii) variable time step dt to show that the simulations are not sensitive to these changes. Some figures use the included function fitT.m which fits a single time constant to exponential data. In all cases which use a recurrent loop it has been implemented by solving the algerbaic loop directly.
