The superficial pyramids, in all areas of neocortex, seem to be
recurrently excitatory. See J.S. Lund et al, "Comparison of intrinsic
connectivity in different areas of macaque monkey cerebral cortex,"
CEREBRAL CORTEX 3:148-162 (March/April 1993). And, at least in visual
cortex, they are in all primates and cats. The only failure to find the
same pattern is, it is said, in rats.
