  2. Ependyma - Wikipedia

    en.wikipedia.org/wiki/Ependyma

    Modified tight junctions between epithelial cells control fluid release. This release allows free exchange between CSF and nervous tissue of brain and spinal cord. This is why sampling of CSF, such as through a spinal tap, provides information about the whole CNS.

  3. Allen Brain Atlas - Wikipedia

    en.wikipedia.org/wiki/Allen_Brain_Atlas

    Unveiled in July 2008, the Allen Mouse Spinal Cord Atlas was the first genome-wide map of the mouse spinal cord ever constructed. The spinal cord atlas is a map of genome wide gene expression in the spinal cord of adult and juvenile C57 black mice. The initial unveiling included data for 2,000 genes and an anatomical reference section. A plan ...

  4. Lateral corticospinal tract - Wikipedia

    en.wikipedia.org/wiki/Lateral_corticospinal_tract

    The lateral corticospinal tract is a descending motor pathway that begins in the cerebral cortex, decussates in the pyramids of the lower medulla [1] (also known as the medulla oblongata or the cervicomedullary junction, which is the most posterior division of the brain [2]) and proceeds down the contralateral side of the spinal cord.

  5. Brain mapping - Wikipedia

    en.wikipedia.org/wiki/Brain_mapping

    According to the definition established in 2013 by Society for Brain Mapping and Therapeutics (SBMT), brain mapping is specifically defined, in summary, as the study of the anatomy and function of the brain and spinal cord through the use of imaging, immunohistochemistry, molecular & optogenetics, stem cell and cellular biology, engineering ...

  6. Corticospinal tract - Wikipedia

    en.wikipedia.org/wiki/Corticospinal_tract

    These cells are notable because of their rapid conduction rate, over 70m/sec, the fastest conduction of any signals from the brain to the spinal cord. [4] There are two divisions of the corticospinal tract, the lateral corticospinal tract and the anterior corticospinal tract. The lateral corticospinal tract neurons cross the midline at the ...

  7. Topographic map (neuroanatomy) - Wikipedia

    en.wikipedia.org/wiki/Topographic_map_(neuroanatomy)

    Unlike the topographic maps of the senses, the neurons of the motor cortex are efferent neurons that exit the brain instead of bringing information to the brain through afferent connections. The motor system is responsible for initiating voluntary or planned movements ( reflexes are mediated at the spinal cord level, so movements associated ...

  9. Ventricular system - Wikipedia

    en.wikipedia.org/wiki/Ventricular_system

    The ventricular system is continuous with the central canal of the spinal cord from the fourth ventricle, [3] allowing for the flow of CSF to circulate. [ 3 ] [ 4 ] All of the ventricular system and the central canal of the spinal cord are lined with ependyma , a specialised form of epithelium connected by tight junctions that make up the blood ...
