MRI Atlas of the Infant Rat Brain: Brain Segmentation features an entirely new coronal, sagittal and horizontal set of tissue cut in regular 9 m intervals with accompanying photographs of MRI data and color drawings of selected brain regions in the three planes. The use of the single brain allows for greater consistency between sections, while color masking offers advances in manual segmentation techniques with increased refinement in the definition of brain areas. Readers will benefit from uniform and consistent manual tissue segmentation of MRI data in an infant rat brain. This volume provides readers the first infant rat brain MRI atlas and a valuable resource in research analyses of the developing brain for structural and functional MRI analyses.
