The subicular complex comprises a set of four related structures including the prosubiculum, presubiculum, postsubiculum and parasubiculum.

[1] The subiculum got its name from Karl Friedrich Burdach in his three-volume work Vom Bau und Leben des Gehirns (Vol.

The subicular complex receives input from CA1 and entorhinal cortical layer III pyramidal neurons and is the main output of the hippocampus proper.

The pyramidal neurons in the subiculum exhibit transitions between two modes of action potential output: bursting and single spiking.

Four component areas have been described:[3] parasubiculum (adjacent to the parahippocampal gyrus), presubiculum, postsubiculum, and prosubiculum.
