From Atoms to Neuronal Spikes: A Multiscale Simulation Framework.

ABSTRACT: Understanding how molecular events in ion channels impact neuronal excitability, as derived from the calculation of the time course of the membrane potentials, can help elucidate the mechanisms of neurological disease-linked mutations and support neuroactive drug design. Here, we propose a multiscale simulation approach which couples molecular simulations with neuronal simulations to predict the variations in membrane potential and neural spikes. We illustrate this through two examples. First, molecular dynamics simulations predict changes in current and conductance through the AMPAR neuroreceptor when comparing the wild-type protein with certain disease-associated variants. The results of these simulations inform morphologically detailed models of cortical pyramidal neurons, which are sim
