The walls of the cerebral ventricles in the developing embryo harbor the primary neural stem cells from which most neurons and glia derive. In many vertebrates, neurogenesis continues postnatally and into adulthood in this region. Adult neurogenesis at the ventricle has been most extensively studied in organisms with small brains, such as reptiles, birds, and rodents. In reptiles and birds, these progenitor cells give rise to young neurons that migrate into many regions of the forebrain. Neurogenesis in adult rodents is also relatively widespread along the lateral ventricles but migration is largely restricted to the rostral migratory stream into the olfactory bulb. Recent work indicates that the wall of the lateral ventricle is highly regionalized with progenitor cells giving rise to different types of neurons depending on their location. In species with larger brains, young neurons born in these spatially specified domains become dramatically separated from potential final destinations. Here we hypothesize that the increase in size and topographical complexity (e.g. intervening white matter tracts) in larger brains may severely limit the long-term contribution of new neurons born close to, or in, the ventricular wall. We compare the process of adult neuronal birth, migration, and integration across different species with different brain sizes, and discuss how early regional specification of progenitor cells may interact with brain size and affect where and when new neurons are added.

“…Moreover, the digital format allows the application of image processing algorithms for quantification or automatic segmentation as well as comparisons between different subject acquisitions. Digital brain atlases have been developed for a number of species used in research, including mouse [7]–[12], rat [13], [14], canary [15] or monkey [16]–[19].…”

A Magnetic Resonance Image Based Atlas of the Rabbit Brain for Automatic Parcellation

et al. 2013

Rabbit brain has been used in several works for the analysis of neurodevelopment. However, there are not specific digital rabbit brain atlases that allow an automatic identification of brain regions, which is a crucial step for various neuroimage analyses, and, instead, manual delineation of areas of interest must be performed in order to evaluate a specific structure. For this reason, we propose an atlas of the rabbit brain based on magnetic resonance imaging, including both structural and diffusion weighted, that can be used for the automatic parcellation of the rabbit brain. Ten individual atlases, as well as an average template and probabilistic maps of the anatomical regions were built. In addition, an example of automatic segmentation based on this atlas is described.

“…Ruffins et al and Vellema et all. (22,27) have composed atlases in detail using MR images, but they examined prenatal and postnatal anatomic structures which are not exactly corresponds to our research. Therefore, data collected from our MR images can be used to create a comparative avian body atlas for anatomy education or avian researchers and clinicians in the future.…”

“…Especially tissues which have high fat and water ratio can be readily visualized and quantified in virtual slices with T1-weighted (W) MR sequences, and then summed across slices to calculate body composition (9). MRI gives us the opportunity to investigate the avian body parts from a three-dimensional (3D) capturing (22,27,28). MR can also provide important data about the egg composition or the embryonic development of the birds (4,7,13).…”

“…Considering about the abdominal organs, for instance, kidneys embedded into the lumbosacral bone, in males, testicles take a large space inside the body cavity, and the gaster consists of two different parts as is known (15,17). Although current MR studies based on the anatomy or physiology of domestic birds were available (2,5,20,22,27), an anatomic evaluation for the abdominal organs comparing the MR images with the cadaver slices on birds might be useful for the researchers working on avian. With this study we tried to prepare an anatomical reference which combines and compares the data on the organic cross-sections and the MR images.…”

Summary:Imaging studies conducted on the modern imaging techniques for birds are limited and probably insufficient for the clinicians. As in mammals, magnetic resonance (MR) imaging (MRI) can be used as a convenient method for the diagnosis and treatment of the avian diseases. In this study, the whole bodies of 2 male and 2 female chickens were imaged by a 3 Tesla superconductive magnet and 15-channel transmit-receive birdcage coil. After acquisition of three dimensional (3D) T1, T2 and proton density weighted (W) MR images; bodies were frozen in same position with the one in imaging process and sliced from matching sections with original and reformatted MR images. Anatomic structures were identified and labeled in both MR images and cadaver sections. After that, 3D multiplanar reconstruction was performed on the MR images. On T1W images, it was observed that the anatomical details were superior due to the high geometric resolution. On T2W images, the tissue contrast differences and fluid filled ducts were clearly detected. On three orthogonal and oblique planes reformatted and maximum intensity projection (MIP) colored images, the anatomic details were more clearly determined and the tissues were more easily distinguished from each other with high geometric and contrast resolution. The aim of this study was to define MRI features of the tissues, and to provide an overview of MRI anatomy of the avian body structures. Besides, the most convenient sequences for the avian MRI were also designated.
