... domestic and wild strains, but more specific data on cell sizes and numbers are often lacking. Methods: We quantified cerebellar anatomy in two domesticated strains (Long-Evans and Sprague-Dawley) and one wild type of brown rat (Rattus norvegicus). Using unbiased stereology, we measured the total...

... Stereology Animal sensory systems are crucial for survival and can detect a large variety of stimuli ranging from electromagnetic fields to large aromatic molecules. The ability to perceive information carried by light is purportedly one of the strongest selective forces in nature, and a large number...

... (somatomotor, M1; somatosensory, S1; auditory, A1; and visual, V1; each in a wider sense). Morphological and design-based stereological analysis was performed in the wild boar ( Sus scrofa scrofa ) as a representative terrestrial hoofed animal (artiodactyl) and the common dolphin ( Delphinus delphis...

...) with histological and stereological methods. For comparison, we included brains of other toothed whale species. Design-based stereology was applied to the primary neocortical areas (M1, S1, A1, V1) of the Indian river dolphins and compared to those of the bottlenose dolphin with respect to layers III and V...

... of branches, where it forages for exudates and crawling invertebrates with its head held very close to the substrate. Here, we asked whether the retina of the potto displays topographic specializations in neuronal density that correlate with its unusual lifestyle. Using stereology and retinal wholemounts, we...

... is known about the visual systems of these birds. In this study, we measured eye morphology in 5 hummingbird species. For 2 of these species, we used stereology and retinal whole mounts to study the topographic distribution of neurons in the ganglion cell layer. Eye morphology (expressed as the ratio...

... ansorgei) . Using retinal wholemounts and stereology, we found that rods are more numerous (42,500,000; 92%) than cones (3,900,000; 8%). Rod densities form a concentric and dorsotemporally asymmetric plateau that matches the location and shape of a bright yellow tapetum lucidum located within the dorsal...

...). In this study, we investigated the neural cell distribution in the ganglion cell layer of a range of lanternfish species belonging to 10 genera. Analyses were performed on wholemounted retinas using stereology. Topographic maps were constructed of the distribution of all neurons and both ganglion and amacrine...

... must maximise light absorption in order to enhance the detection of prey, predators and potential mates. Using stereological analysis of retinal wholemounts, the distribution and number of photoreceptors (rods) was determined for 5 deep-sea shark species from a range of depths (46-1,500 m). All species...

.... In this study, we used retinal wholemounts and stereological methods to estimate the total number and topographic distribution of retinal ganglion cells in addition to an anatomical estimate of spatial resolving power in two species of penguins: the little penguin, Eudyptula minor, and the king penguin...

Oelschläger We investigated the quantitative morphology of the neocortex (gray matter) in 2 toothed whale (odontocete) species (harbor porpoise, Phocoena phocoena ; bottlenose dolphin, Tursiops truncatus ) with stereological methods. The 4 primary...

...Chet C. Sherwood; Ralph L. Holloway; Joseph M. Erwin; Patrick R.
