A Study On Brain Atlases - 3056 Words

1. ABSTRACT A region of embryonic rat brain was digitally photographed with an Olympus BX40 Microscope equipped with a 10MP (MU1000) video camera using four different objectives (4x, 10x, 20x, 40x). The different objectives were used to analyze the value of different resolutions in balancing the amount of work needed to make the pictures with the worth (or information value) of the image when using Photoshop (version 12.0). The images captured were montaged and arranged into series. This information will be used in preparation of a digital microscopic atlas of different aged embryonic rat brains. 2. INTRODUCTION 2.1. Brain Atlases in General An atlas of a brain can help locate specific structures, as well as give an understanding to size and structure of a brain. A brain atlas can be widely used in neuroscience research and education. In neuroscience, brain atlases are just as important as a map is in geography, and they can be accessed worldwide (Bakker, et al., 2015). Although no two brains are identical, it is important to refer to a multitude of atlases while studying a brain. Structures that may not be exactly the same in two brains include: cytoarchitecture, chemoarchitecture, blood flow distributions, metabolic rates, behavioral and pathologic correlates and a multitude of other structures (Mazziotta, et al., 1995). A brain atlas can differ from brain to brain, which may be a result of evolution, maturation, and/or abnormalities.

It is also the most difficult to understand, given the vast array of different functions spread throughout its mass and the interconnected functionality of its regions that makes subdividing it based on form or function a difficult task. Craddock, et al. (2012), in the article examined, attempt to produce a method for further examining the functional connectivity (FC) of the regions of the brain and subdivide themRead MoreIntegrating Histology And Mri On The First Digital Brain Of Common Squirrel Monkey2812 Words   |  12 PagesIntegrating histology and MRI in the first digital brain of common squirrel monkey, Saimiri sciureus Peizhen Suna, Prasanna Parvathanenia, Kurt G.
