Metric features and modular and laminar distributions of intrinsic projections of area 17 were studied in Cebus apella. Anterogradely and retrogradely labeled cell appendages were obtained using both
saturated pellets and iontophoretic injections of biocytin into the
operculum. Laminar and modular distributions of the labeled processes were analyzed using Nissl counterstaining, and/or cytochrome
oxidase and/or NADPH-diaphorase histochemistry. We distinguished
three labeled cell types: pyramidal, star pyramidal and stellate cells located in supragranular cortical layers (principally in layers IIIa, IIIb α, IIIb ß and IIIc). Three distinct axon terminal morphologies were
found, i.e., Ia, Ib and II located in granular and supragranular layers.
Both complete and partial segregation of group I axon terminals
relative to the limits of the blobs of V1 were found. The results are
compatible with recent evidence of incomplete segregation of visual
information flow in V1 of Old and New World primates. |
