A simple procedure of vibratome sectioning the organ of Corti, followed by immunohistochemistry and confocal microscopy is described. This procedure allows for improved preservation of the fine cytoarchitecture of the mammalian organ of Corti, and consequently allows for accurate quantification of cell types.

An Introduction to Neuroanatomy

2023
Neuroanatomy is the study of nervous system structures and how they relate to function. One focus of neuroanatomists is the macroscopic structures within the central and peripheral nervous systems, like the cortical folds on the surface of the brain. However, scientists in this field are also interested in the microscopic relationships between neurons and glia - the two major cell types of the nervous system. This video provides a brief overview of the history of neuroanatomical research,...

Organotypic hippocampal slice cultures (OHSC) represent an in vitro model that simulates the in vivo situation very well. Here we describe a vibratome-based improved slicing protocol to obtain high quality slices for use in assessing the neuroprotective potential of novel substances or the biological behavior of tumor cells.

2017
This manuscript details the fabrication of micro-tissue engineered neural networks: three-dimensional micron-sized constructs comprised of long aligned axonal tracts spanning aggregated neuronal population(s) encased in a tubular hydrogel. These living scaffolds can serve as functional relays to reconstruct or modulate neural circuitry or as biofidelic test-beds mimicking gray-white matter neuroanatomy.
FAQs
Researchers compare several features together rather than relying on a single cellular trait. Neuronal and glial distributions, cell size and density, cellular morphology, and the presence or organization of layers can reveal differences between adjacent areas. This combined structural profile helps establish cortical and subcortical boundaries with greater anatomical specificity.
Cellular organization provides an anatomical framework for interpreting how brain regions differ in their connections and functions. When cytoarchitectonic boundaries are identified, researchers can relate those regions to connectivity patterns and functional roles. This connection is important for explaining how differences in local cellular arrangement may contribute to cognition and behavior.
Laminar patterns provide information about how cells are arranged across the depth of nervous tissue. Differences in layering can help distinguish cortical areas and define boundaries that may not be evident from broad anatomical location alone. Examining these patterns alongside cell morphology and density strengthens structural comparisons among brain regions.
Comparing cellular organization across healthy, developing, and diseased nervous systems allows researchers to identify differences in neuronal and glial distributions, morphology, density, or layering. These comparisons provide a structural way to investigate nervous-system change over time or with disease. The resulting observations can support studies of neurological disorders and their anatomical correlates.
A typical workflow examines tissue sections for neuronal and glial distributions, cellular morphology, density, and laminar patterns. Histological staining or molecular markers reveal the relevant cellular features for analysis. Researchers then use the observed patterns to characterize regions and assess possible boundaries, creating a structural basis for subsequent anatomical or functional interpretation.
Histological staining and molecular markers are used to reveal cellular features in tissue sections. These approaches help researchers examine the distribution and morphology of neurons and glia, as well as laminar organization. Selecting such tissue-based evidence is especially relevant when the goal is to define regional structure or compare cellular organization across experimental conditions.
Cytoarchitectonic maps provide structurally defined regions that can be incorporated into brain atlases and used when interpreting neuroimaging data. By linking cellular organization with anatomical boundaries, these maps help researchers relate observed imaging patterns to specific brain areas. They therefore support more informed comparisons between structural organization, connectivity, and function.
Cytoarchitecture can support investigations of how cellular organization contributes to cognition, behavior, and neurological disorders. Researchers may compare regional patterns across healthy, developing, or diseased nervous systems, then relate those differences to connectivity or function. This makes the approach useful for connecting microscopic tissue organization with broader neuroscientific questions.
