Figure 4From: Diffusion laws in dendritic spinesLeft: The NET of Brownian motion on a sphere with a bottleneck connected by a smooth funnel to the neck (dashed line), and with a non-smooth connection (continuous line). Right: The NET of Brownian motion in a ball with a bottleneck connected by a smooth funnel to the neck (dashed line), and with a non-smooth connection (continuous line).Back to article page
