(1) In the external plexiform layer, a reduced number of mature dendrodendritic synapses and signs of harmed granule gemmules were observed.
(2) F1 knobs contain flattened synaptic vesicles and form symmetrical junctions with F2 knobs, gemmules, spines, and small-medium dendrites in synaptic islands, throughout the neuropil, and on the proximal dendrites and soma of the largest type of neuron.
(3) In electron micrographs of the external plexiform layer, the gemmules which arise from the distal dentrites of granule cells were also observed to be filled with reaction product, and these structures corresponded in size and location to the puncta observed in light microscopic preparations.
(4) Gametogenesis occurs shortly after gemmule hatching in both males and females but slightly later in males.
(5) F2 knobs are irregularly shaped, contain pleiomorphic synaptic vesicles and make symmetrical junctions primarily with gemmules and spines in synaptic islands.
(6) An excess of thyroid hormones therefore causes neuronal proliferation to end precociously leading to a reduction of the total number of gemmules.
(7) Cellular fragments phagocyted by the thesocytes during the gemmule formation undergo a condensation and rearrangement of their constituent elements before forming a definitive platelet.
(8) It has recently been claimed by Ramon-Moliner29, that reciprocal synapses between mitral (and tufted) cell dendrites and granule cell gemmules, which for more than 10 years have been thought to represent a major feature of the structural and functional organization of the olfactory bulb28, are non-existent or, at best, extremely rare.
(9) They are found primarily in "synaptic islands" making contact with gemmules, spines, small dendrites, and other synaptic profiles containing pleiomorphic synaptic vesicles (F2).
(10) The gemmules were observed to form reciprocal dendrodentritic synaptic junctions with mitral cell dentrites which lacked reaction product.
(11) Hypothyroidism may lead to cellular hypoplasia and reduced dendritic ramification, gemmules and interneuronal connections.
(12) They migrate with their growth cones oriented toward the olfactory bulb from the level of the anterior lateral ventricle into the granular layer of the olfactory bulb, where they differentiate into the definitive granule cells: their somata enlarge; the leading processes elongate, branch, sprout many gemmules, and become the peripheral processes; and the trailing processes become the basal dendrites.
(13) It is suggested that a granule-to-mitral dendro-dendritic synapse only forms next to an already existing mitral-to-granule synapse on the same gemmule.
(14) The large amount of geographic overlap of retinal and cortical terminals on gemmules, spines, and small dendrites found in the neuropil outside of synaptic islands logically would maximize axonal sprouting between these two sources.
Reproduction
Definition:

(6) The La Parguera facility was established in part to contrast the social behavior of free-ranging groups with that in enclosures, as well as to compare the seasonal events linked to reproduction with those at Cayo Santiago.
(7) Thus, the carotid pulse tracing provides an accurate reproduction of the morphology of the pressure tracing recorded from the ascending aorta, and when calibrated by peripheral blood pressure measurement, it can be used to calculate LV pressure throughout ejection.
(8) Somewhat surprisingly then, in view of the mechanisms in mammals, birds do not seem to use this seasonal message in the photoperiodic control of reproduction.
(9) Such factors can mask any interactions between biologic factors of the aging female reproductive system and other social factors that might otherwise detemine fertility during the later reproductive years.
(10) The results indicate that additional feed in late gestation improves reproductive performance in sows.
(11) Here we show that the subsequent survival and reproductive success of subordinate female red deer is depressed more by rearing sons than by rearing daughters, whereas the subsequent fitness of dominant females is unaffected by the sex of their present offspring.
(12) The variations in behavior and physiology across the year were considered in terms of factors constraining the timing of the natural reproductive pattern.
