  2. Hypothalamospinal tract - Wikipedia

    en.wikipedia.org/wiki/Hypothalamospinal_tract

    The tract descends through the periaqueductal gray, [5] through the dorsal longitudinal fasciculus, [1] and adjacent to the reticular formation. [5] In the brainstem, it descends in the lateral tegmentum of the midbrain, pons, and medulla oblongata. In the spinal cord, it descends in the dorsolateral quadrant of the lateral funiculus. [6]

  3. 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.

  4. Neural pathway - Wikipedia

    en.wikipedia.org/wiki/Neural_pathway

    A neural pathway connects one part of the nervous system to another using bundles of axons called tracts. The optic tract that extends from the optic nerve is an example of a neural pathway because it connects the eye to the brain; additional pathways within the brain connect to the visual cortex.

  5. Descending neuron - Wikipedia

    en.wikipedia.org/wiki/Descending_neuron

    Some descending pathways form direct connections with motor neurons and premotor interneurons, [25] including central pattern generators. [26] But how exactly descending signals are integrated in circuits in the spinal cord (vertebrates) or ventral nerve cord (invertebrates) during behavior is not well understood. [3] [27]

  6. Pyramidal tracts - Wikipedia

    en.wikipedia.org/wiki/Pyramidal_tracts

    The pyramidal tracts include both the corticobulbar tract and the corticospinal tract.These are aggregations of efferent nerve fibers from the upper motor neurons that travel from the cerebral cortex and terminate either in the brainstem (corticobulbar) or spinal cord (corticospinal) and are involved in the control of motor functions of the body.

  7. Brain mapping - Wikipedia

    en.wikipedia.org/wiki/Brain_mapping

    It shows neurons and their connections along with blood vessels and other components of a millionth of a brain. For the map, the 1 mm³ sized fragment was sliced into about 5,300 pieces of about 30 nanometer thickness which were then each scanned with an electron microscope. The interactive map required 1.4 petabytes of storage-space.

  8. Vestibulospinal tract - Wikipedia

    en.wikipedia.org/wiki/Vestibulospinal_tract

    Like other descending motor pathways, the vestibulospinal fibers of the tract relay information from nuclei to motor neurons. [1] The vestibular nuclei receive information through the vestibulocochlear nerve about changes in the orientation of the head. The nuclei relay motor commands through the vestibulospinal tract.

  9. Dopaminergic pathways - Wikipedia

    en.wikipedia.org/wiki/Dopaminergic_pathways

    Dopaminergic pathways (dopamine pathways, dopaminergic projections) in the human brain are involved in both physiological and behavioral processes including movement, cognition, executive functions, reward, motivation, and neuroendocrine control. [1] Each pathway is a set of projection neurons, consisting of individual dopaminergic neurons.
