abstract = {In the present study we reevaluated the parcellation scheme
of the macaque frontal agranular cortex by implementing
quantitative cytoarchitectonic and multireceptor analyses,
with the purpose to integrate and reconcile the
discrepancies between previously published maps of this
region.We applied an observer-independent and statistically
testable approach to determine the position of
cytoarchitectonic borders. Analysis of the regional and
laminar distribution patterns of 13 different transmitter
receptors confirmed the position of cytoarchitectonically
identified borders. Receptor densities were extracted from
each area and visualized as its “receptor fingerprint”.
Hierarchical and principal components analyses were
conducted to detect clusters of areas according to the
degree of (dis)similarity of their fingerprints. Finally,
functional connectivity pattern of each identified area was
analyzed with areas of prefrontal, cingulate, somatosensory
and lateral parietal cortex and the results were depicted as
“connectivity fingerprints” and seed-to-vertex
connectivity maps.We identified 16 cyto- and receptor
architectonically distinct areas, including novel
subdivisions of the primary motor area 4 (i.e. 4a, 4p, 4m)
and of premotor areas F4 (i.e. F4s, F4d, F4v), F5 (i.e. F5s,
F5d, F5v) and F7 (i.e. F7d, F7i, F7s). Multivariate analyses
of receptor fingerprints revealed three clusters, which
first segregated the subdivisions of area 4 with F4d and F4s
from the remaining premotor areas, then separated
ventrolateral from dorsolateral and medial premotor areas.
The functional connectivity analysis revealed that medial
and dorsolateral premotor and motor areas show stronger
functional connectivity with areas involved in visual
processing, whereas 4p and ventrolateral premotor areas
presented a stronger functional connectivity with areas
involved in somatomotor responses.For the first time, we
provide a 3D atlas integrating cyto- and multi-receptor
architectonic features of the macaque motor and premotor
cortex. This atlas constitutes a valuable resource for the
analysis of functional experiments carried out with
non-human primates, for modeling approaches with realistic
synaptic dynamics, as well as to provide insights into how
brain functions have developed by changes in the underlying
microstructure and encoding strategies during evolution.},
