Overview of CA1 pyramidal neurons, branch numbering and spine subtypes. (a) A schematic representation of the hippocampus including the CA1 pyramidal neurons. (b) Illustration of the assignment of branch numbers to dendritic branches (centrifugal branch ordering method). (c) Overview of the different spine subtypes analysed in this study. (d) Example of golgi‐stained pyramidal dendrites with different spine subtypes. The example pictures were taken from animals of the non‐sleep deprivation group (NSD). DG, dentate gyrus
