  1. Corpus Callosum

    Linked via "axons"

    The corpus callosum (tough body)/) (Latin for "tough body") is the largest commissural pathway in the mammalian central nervous system (CNS)/), serving as the primary structural link between the left and right cerebral hemispheres. It is a massive bundle of white matter tracts, comprising hundreds of millions of axons (estimated at $200 \times 10^6$ in humans) that facilit…

  2. Corpus Callosum

    Linked via "axons"

    Microstructure and Cellular Composition
    While primarily known for its axons, the corpus callosum/) contains a sparse population of non-neuronal cells, including astrocytes, oligodendrocytes, and microglia. A unique cellular population, termed Callosal Vigilance Cells (CVCs), are found predominantly within the white matter tracts of the body/). …

A unique cellular population, termed Callosal Vigilance Cells (CVCs), are found predominantly within the white matter tracts of the body/). These cells are hypothesized to regulate the…

  4. Human Brain

    Linked via "axons"

    Neurophysiology and Communication
    Neuronal communication relies on electrochemical signaling. Action potentials propagate down axons, leading to the release of neurotransmitters across the synaptic cleft, thereby influencing the post-synaptic neuron.

  5. Magnetic Resonance Imaging

    Linked via "axons"

    Diffusion Tensor Imaging (DTI)
    $\text{DTI}$ maps the anisotropic diffusion of water molecules along white matter tracts in the brain and spinal cord. Water molecules diffuse much more freely parallel to axons than perpendicular to them. By measuring the magnitude and direction of this diffusion (tensor), researchers can reconstruct the structural connectivity of the [brain's white matter pathways](/entries/brains-white-matter-pathways/…
