abstract = {The medial prefrontal cortex (mPFC) has been implicated in
cognitive and executive processes including decision making,
working memory and behavioral flexibility. Cortical
processing depends on the interaction between distinct
neuronal cell types in different cortical layers. To better
understand cortical processing in the rat mPFC, we studied
the diversity of pyramidal neurons using in vitro whole-cell
patch clamp recordings and biocytin staining of neurons,
followed by morphological analysis. Using unsupervised
cluster analysis for the objective grouping of neurons, we
identified more than 10 different pyramidal subtypes spread
across the different cortical layers. Layer 2 pyramidal
neurons possessed a unique morphology with wide apical
dendritic field spans and a narrow basal field span. Layer 3
contained the only subtype that showed a burst of action
potentials upon current injection. Layer 5 pyramidal neurons
showed the largest voltage sags. Finally, pyramidal neurons
in layer 6 (L6) showed a great variety in their morphology
with $39\%$ of L6 neurons possessing tall apical dendrites
that extend into layer 1. Future experiments on the
functional role of the mPFC should take into account the
great diversity of pyramidal neurons.},
