Studies suggest that the Af9 protein acts as a repressor of Tbr1 in the upper layers of the six-layer developing cerebral cortex, thereby confining Tbr1 to the lower cortical layers ( preplate, subplate, layer VI ).

Intimately related to the RUH is the'protomap'hypothesis, which states that the primordial identity of each functional area of the cerebral cortex is encoded within the cortical stem cells prior to the formation of the cortical layers.
33.
These cytoarchitectural abnormalities were mainly or exclusively localized in the upper cortical layers of the limbic allocortex, including circumscribed malformations, nerve cell alterations as well as cytoarchitectural deviations attributable to disruptions of neural migration in the second trimester of gestation.
34.
At 17 days, primordial follicles, each of consists of a small oocyte ( with no zona pellucida ) and a single layer of flattened pre-granulosa cells, can first be observed in the cortical layer of the ovary.
35.
The "'barrel cortex "'refers to a region of somatosensory cortical layer IV that are visibly darker when stained to reveal the presence of cytochrome c oxidase, and are separated from each other by lighter areas called septa.
36.
The Fibroblast Growth Factor ( FGF )-and Sonic Hedgehog ( SHH )-signaling pathways have recently been reported to be able to induce healthy cortical folds, with a full complement of cortical layers, in mice that live to adulthood.
37.
DNMT1 ) and Reelin mRNA expression in cortical layers I and V of schizophrenic patients and normal controls demonstrated that in the layer V both DNMT1 and Reelin levels were normal, while in the layer I DNMT1 was threefold higher, probably leading to the twofold decrease in the Reelin expression.

Tuckerman distinguished " Ramalina ceruchis " and " R . homalea " from other species of " Ramalina " as having medullary cords free of the cortical layer, and at length axial; or indistinct and having spermogones black ( black pycnidia ).
39.
The structure of the neocortex is relatively uniform ( hence the alternative names " iso-" and " homotypic " cortex ), consisting of six horizontal layers segregated principally by synaptic connections from outside the cortex ( mostly from thalamus ), and themselves make short-range, local connections to other cortical layers.

Fertilization of the egg causes a rotation of the outer cortical layers, moving clusters of the " Frizzled " and " Dsh " proteins closer to the equatorial region . ?-catenin will be enriched locally under the influence of Wnt signaling pathway in the cells that inherit this portion of the cytoplasm.
