abstract = {Cajal–Retzius (CR) cells are early generated neurons,
involved in the assembly of developing neocortical and
hippocampal circuits. However, their roles in networks of
the postnatal brain remain poorly understood. In order to
get insights into these latter functions, we have studied
their morphological and synaptic properties in the postnatal
hippocampus of the CXCR4-EGFP mouse, where CR cells are
easily identifiable. Our data indicate that CR cells are
nonuniformly distributed along different subfields of the
hippocampal formation, and that their postnatal decline is
regulated in a region-specific manner. In fact, CR cells
persist in distinct areas of fully mature animals.
Subclasses of CR cells project and target either local
(molecular layers) or distant regions [subicular complex and
entorhinal cortex (EC)] of the hippocampal formation, but
have similar firing patterns. Lastly, CR cells are biased
toward targeting dendritic shafts compared with spines, and
produce large-amplitude glutamatergic unitary postsynaptic
potentials on γ-aminobutyric acid (GABA) containing
interneurons. Taken together, our results suggest that CR
cells are involved in a novel excitatory loop of the
postnatal hippocampal formation, which potentially
contributes to shaping the flow of information between the
hippocampus, parahippocampal regions and entorhinal cortex,
and to the low seizure threshold of these brain areas.},
