Here, labelled cells were also scattered across the deepest layer of area 23b.
Only small numbers of cells were seen in the deepest layer of area 31, close to the area 23 border.
Label was found near the rostral border with area 24 (area 23d) and, caudal to that, every section contained DY-labelled cells in the deepest layer of areas 23a, 23b, 29 and 30, but these cells were limited in number (e.g., 10 20 cells per section in total).
Labeled fibers were present just deep to posterior area 25 in all 3 hemispheres, along with evidence of light terminal label in deep layer I of area 25 (which sometimes reached superficial layer II).
CaC crystal prevalence ranged from 45% in the deep layer of the medial femoral condyle to 70% in the superficial layer of the medial femoral condyle, with no significant difference between superficial and deep areas.
All rats sustained some limited damage dorsal to the hippocampus, including the deep layers of the primary somatosensory area, the parietal region of the posterior association area, and at posterior sections parts of the primary and rostrolateral visual areas were damaged.
Furthermore, we distinguished superficial and deep layers of equal thickness in all areas.
The last one, in 1821, which began with days of explosive eruptions, left deep layers of dark-gray ash through vast areas of southern Iceland — some of it nearly reached Reykjavik — and it caused the Markarfljot and the Holtsa rivers to flood.
Near the border with area 24, label was present in 23d, followed more caudally by large numbers of labelled cells across the deepest layers of rostral areas 29, 30 and 23 (Fig. 7).
At these very caudal levels, labelled cells were also present in the ventral retrosplenial cortex, and these cells were continuous with label extending dorsally from the presubiculum into the deepest layers of ventral areas 29 and 30 (Fig. 11).
