Figure 4From: Anomalous ion diffusion within skeletal muscle transverse tubule networksThe mean squared displacement (MSD) in K+ transport as a function of time for a random walk on the human t-tubule network (—) and an unrestricted random walk in two dimensions (– – –). The tubules significantly obstruct the transport of K+ and the diffusion of K+ in the t-tubule network is anomalous over short distances (i.e. the relationship between MSD and time is not linear as per standard Brownian diffusion (---)).Back to article page
