Bounds of the uniform prior p(θ).

The 10 parameters and two noise amplitudes entering our biophysical model. 5 parameters are variable and the target of our inference procedure; one of the noise amplitudes is latent; all other parameters are kept constant. The bounds of the prior were chosen in agreement with the results of our previous publication Amiri et al. The prior was designed such that the parameter values of Amiri et al. fall within the prior. For the two noise amplitudes we chose values that produced results that were in quantitative agreement with experiments.
