“…Third, cortical neurons in vitro produce responses to white noise currents that share properties of in vivo activity, and Gaussian white noise provides a basic model for the distribution of total current inputs at the soma under conditions of intense synaptic bombardment (Mainen and Sejnowski, 1995;Destexhe et al, 2001;Rauch et al, 2003). Finally, modeling work has shown that, under many circumstances, conductancedriven stimuli produce similar responses to white noise current stimuli: in models that capture key properties of experimentally recorded neurons, the response properties of model neurons driven by conductance stimuli map onto the response properties of equivalent neurons driven by current stimuli (Rauch et al, 2003;Jolivet and Gerstner, 2004;La Camera et al, 2004;Richardson, 2004;Jolivet et al, 2006).…”
