The Table shows the case descriptor, species (Sp) of macaque (Rh, rhesus; Cy, cynomolgus), centre of injection site (in bold), type of tracer (DY, diamidino yellow; FB, fast blue; HRP, horseradish peroxidase), Left or Right hemisphere (L, R), site of any other injections with the same tracer in the opposite hemisphere (in parentheses), and location of cingulate label in hemisphere of injection site. The term ‘None’ refers to those cases with just one injection of a given tracer. The density of retrograde label is marked on a scale from zero to ++++. The symbol + indicates just an average of 2–5 cells per section in each area, while sporadic label (i.e., even less) is marked with *. The absence of label is indicated with a 0. AD, anterior dorsal thalamic nucleus; AM, anterior medial thalamic nucleus; AV, anterior ventral thalamic nucleus; Cdc, nucleus centralis densocellularis; CM, centrum medianum; LD, laterodorsal thalamic nucleus; mc, magnocellular; MD, medial dorsal thalamic nucleus; Mid, midline thalamic nuclei; pc, parvocellular; PCN, paracentral nucleus; Re, nucleus reuniens.
