Knowing What Counts: Unbiased Stereology in the Non-human Primate Brain
The non-human primate is an important translational species for understanding the normal function and disease processes of the human brain. Unbiased stereology, the method accepted as state-of-the-art for quantification of biological objects in tissue sections, generates reliable structural data for biological features in the mammalian brain. The key components of the approach are unbiased (sys...
متن کاملExtending Unbiased Stereology of Brain Ultrastructure to Three-dimensional Volumes
Design and Measurements: Volumes are reconstructed by defining transformations that align the entire area of adjacent sections. Whole-field alignment requires rotation, translation, skew, scaling, and second-order nonlinear deformations. Such transformations are implemented by a linear combination of bivariate polynomials. Computer software for generating transformations based on user input is ...
متن کاملDissecting the Non-human Primate Brain in Stereotaxic Space
The use of non-human primates provides an excellent translational model for our understanding of developmental and aging processes in humans(1-6). In addition, the use of non-human primates has recently afforded the opportunity to naturally model complex psychiatric disorders such as alcohol abuse(7). Here we describe a technique for blocking the brain in the coronal plane of the vervet monkey ...
متن کاملBias in image analysis and its solution: unbiased stereology
Although the human eye is excellent for pattern recognition, it often lacks the sensitivity to detect subtle changes in particle density. Because of this, quantitative evaluation may be required in some studies. A common type of quantitative assessment used for routine toxicology studies is two-dimensional histomorphometry. Although this technique can provide additional information about the ti...
متن کاملSynthesis of Research: Extending Unbiased Stereology of Brain Ultrastructure to Three-dimensional Volumes
OBJECTIVE Analysis of brain ultrastructure is needed to reveal how neurons communicate with one another via synapses and how disease processes alter this communication. In the past, such analyses have usually been based on single or paired sections obtained by electron microscopy. Reconstruction from multiple serial sections provides a much needed, richer representation of the three-dimensional...
