Long-range focal collateralization of axons arising from corticocortical cells in monkey sensory-motor cortex
J DeFelipe, M Conley and EG Jones
Small extracellular injections of HRP were placed into a stratum of
corticocortical axons situated immediately deep to area 3b of the monkey
somatic sensory cortex. This stratum had previously been demonstrated to
contain corticocortical fibers linking the cytoarchitectonic fields of the
somatic sensory cortex to one another and certain of them to the motor
cortex. This method resulted in extremely successful filling of pyramidal
cells, their axons, collateral axon branches, and terminations in areas 3b,
1, and 2 posterior to the injection and in areas 3a and 4 anterior to it.
The major finding was that cells with somata situated in any one of these
fields and with principal axons traversing the injection site have long
collaterals, primarily in layers III and V, which can extend throughout
their own cytoarchitectonic field and into one or more other fields. In
these fields they give off focused, columnlike concentrations of terminal
boutons, which can be separated from one another by 800 micron or more. The
anterogradely labeled, primary corticocortical fibers, traced forwards into
areas 3a and 4, have virtually identical focal terminations. These findings
indicate that interareal connectivity in the sensory-motor cortex can be
effected by the axon branches of single cells rather than by separate
groups of cells, and this may form a basis for the convergence of place and
modality information on single cells in the sensorimotor cortex, a
convergence that is not seen in the thalamic input to this cortex.
