Figure 1From: Diffusion laws in dendritic spinesUpper row: (from left to right) The dendritic spine head is connected smoothly to the neck (the postsynaptic density (PSD) is marked red) and (right) the connection is not smooth (from [6]). Lower row: A mathematical idealization of a cross section: A cross section of a sharp and non-sharp connection approximating the spine morphology.Back to article page
