Example Sentences:

(3) A quantitative study of changes in total cell number was carried out in the indusium griseum and anterior commissure from fetal life to old age in the mouse brain.
(4) Mitotic activity in the indusium griseum levels out at 3 months postnatum with mitotic and pyknotic cells present in roughly equal numbers thereafter.
(5) Neurogenesis and gliogenesis in the indusium griseum were studied in semithin sections and with the electron microscope.
(6) The changes in the number of mitotic and pyknotic cells were recorded in the indusium griseum, anterior commissure, subependymal and ependymal layers over the same period.
(7) It was not possible to separate the indusium griseum from the cingulate cortex until birth.
(8) A similar increase in mitosis was found at 5 days postinjection in the indusium griseum.
(9) One hour after the injection, radioactivity was found to be selectively concentrated in specific neurons of the septum, the hippocampal complex (precommissural hippocampus, cornu Ammonis, gyrus dentatus, subiculum), the indusium griseum, the amygdala and in certain areas of the cortex.
(10) The indusium griseum, which demonstrated the highest binding for corticosterone of all brain regions in the autoradiograms, was taken as reference and defined as 100% relative labeling (RL).
(11) The number of glia in the indusium griseum was similar in both groups but the Gunn rats showed a decrease of about 20% in the number of neutrons in this region.
(12) Other extra-hypothalamic regions displaying a low-to-moderate density of immunoreactive fibers were the indusium griseum, the hippocampus, the fimbria of the fornix, the subcommissural organ, the medial habenula and, occasionally, the medial periaqueductal gray.
(13) First, the structure of pyramidal cells progressively changes from those in the indusium griseum which have predominently round or oval somata and a preponderance of apical and few basal dendrites to those in layer V of retrosplenial cortex and area 23 which have pyramidal shaped somata and a great number of basal dendrites which branch frequently and spread horizontally for hundreds of microns.
(14) Only a few loci of basic FGF synthesis are detected by in situ hybridization and include layers 2 and 6 of the medial (cingulate) cortex, the indusium griseum, fasciola cinereum, and field CA2 of the hippocampus.
(15) A quantitative histological examination of brains from mice aged 25, 28 and 31 months of age showed that there was no loss of neurons from the indusium griseum and the number of glia per 100 neurons also remained constant.
(16) An autoradiographic study of neuronal and glial production was carried out in the indusium griseum of mice.
(17) A quantitative study of the development of the indusium griseum was carried out in mice.
(18) The immunocytochemical features of the indusium griseum (IG) were compared with the corresponding hippocampus in 5 patients with Alzheimer's disease (AD) and 5 age-matched nondemented individuals using antibodies against beta-amyloid, the A68 protein (Alz-50 antibody), tau, ubiquitin and synapsin I. beta-Amyloid-positive plaques were prominent in the AD hippocampus but were not present in the IG.
(19) What was key to observe was whether or not there was an indusium, a tiny veil, over the sorus.
(20) The transition from one cellular layer in the indusium griseum to five cellular layers in area 23 is made by the addition of layers II, III, IV and VI in retrosplenial cortex to the one ganglionic layer of the indusium griseum and subiculum.
Sorus
Definition:
(n.) One of the fruit dots, or small clusters of sporangia, on the back of the fronds of ferns.
Example Sentences:
(1) It is concluded that, contrary to previous reports, spore maturation is a slow process and is not completed until the sorus becomes pigmented.
(2) What was key to observe was whether or not there was an indusium, a tiny veil, over the sorus.
(3) Upon starvation, Dictyostelium amoebae aggregate together and then differentiate into either the stalk or spore cells that, respectively, form the stalk and sorus of the fruiting body.
