Many of the connections of area 46 were found to span long distances (33.41 mm±10.58 mm s.d.; significantly different from those of V4, p<0.0001, with 35 of its 39 connections longer than 18 mm), although we note that some short projections are likely missing because other prefrontal regions were not included in the connection matrix.
Marr's influential model of hippocampal function was prescient of such attractor dynamics, identifying them with associative plasticity in the recurrent connections of area CA3 [18].
The results concerning the anterograde and retrograde labeling after injection in area 5 (PE and PEa) were described separately in another report (Cappe, Morel, and Rouiller 2007), but we used here the retrograde data to compare the thalamic connections of area 5 with the other cortical areas (RAC, CAC, PMd, and PMv) injected in the present study.
The present paper deals with the transit network design problem related to the feeder routes defined as transit services for the connection of local areas, where the demand has to be gathered, with the stops of the main transit network, usually railway or underground station.
For example, the average proportions of short- versus long-range connections for areas of the highest cytoarchitectonic differentiation (type 5) were 65%and9% 9 %, respectively, compared to 45%and25%25 % for those of the lowest differentiation (type 1).
Relative projection frequencies were calculated separately for each value of each anatomical variable by considering all connections between pairs of areas at a particular distance, type difference or hierarchical level difference and assessing how many of them were indeed connected (e.g., determining the frequency of connections among all areas separated by 5 borders).
An essential prerequisite for interpreting neural activity in various areas of the brain is a knowledge of the functional connections of the area of interest.
"The inspection observations suggest the possibility that more attention needs to be devoted to supervision and review activities in connection with the audits of areas involving a high degree of judgment," as well as areas subject to management estimates.
Lou et al. reported functional connections of this area during self-monitoring to both the lateral parietal and the medial prefrontal cortices which are also part of the action monitoring network (Fig. 2).
g., [ 94]], but are also involved in the top-down gating of horizontal connections of this area through feedback projections inhibiting some sets of lateral interactions and/or activating others during geometric selectivity, rather than a simple gain control or a simple reflection of higher sensory processing [e. g., [ 95]].
