"Interneurons in layer 2/3 (L2/3) of the somatosensory cortex show
4 types of axonal projection patterns with reference to the laminae
and borders of columns in rat barrel cortex (Helmstaedter et al.
Here, we analyzed the dendritic geometry and electrical
excitability of these interneurons.
We conclude that
1) dendritic polarity is correlated to intrinsic electrical excitability,
and 2) the axonal projection pattern represents an independent
classifier of interneurons.
