Before revision: Feedback of calcium signaling through calcium-activated potassium channels of a dendritic spine is investigated. To simulate such ion channels and the resulting spatial distribution of concentration, current, and membrane voltage within the dendritic spine , we applythe immersed boundary method with electrodiffusion .
After revision: Feedback of calcium signaling through calcium-activated potassium channels of a dendritic spine by applying the immersed boundary method with electrodiffusion. We simulate the stochastic gating of such ion channels and the resulting spatial distribution of concentration, current, and membrane voltage within the dendritic spine , we applythe immersed boundary method with electrodiffusion .
