Brainstem Disorders by Anja K. E. Horn-Bochtler, Jean A. Büttner-Ennever (auth.),

By Anja K. E. Horn-Bochtler, Jean A. Büttner-Ennever (auth.), Peter Urban, Louis R Caplan (eds.)

The brainstem comprises a number of pathways connecting diversified mind components and the spinal twine, neural networks with coordinating initiatives, and brainstem nuclei. accordingly its topography is complicated, or even skilled neurologists locate it hard to localize brainstem lesions and diagnose brainstem problems. This richly illustrated ebook presents a complete evaluation of brainstem problems and provides the correct scientific wisdom beneficial for analysis. the outlet sections record the brainstem neuroanatomy and talk about present diagnostic tools. the complete spectrum of scientific findings in brainstem issues is then defined, and topodiagnostic points of the neurological findings are defined intimately. The descriptions of mind stem problems are regularly dependent and are supported by means of many MR photographs and brief case stories. as well as basic brainstem lesions, resembling vascular brainstem syndromes, different problems are thought of that don't solely convey brainstem signs or indicators, e.g., a number of sclerosis. This publication will function a useful reference paintings for neurologists in medical perform or additional education.

2004). 13, p. 21). The parasympathetic motoneurons receive direct excitatory input from the pontine micturition center (M-region or Barrington’s nucleus). There is experimental evidence that activation of the M-center can be stimulated by the preoptic region, which terminates in the periaqueductal gray substance and projects to the parabrachial area. The M-region in turn projects to the inhibitory interneurons in the sacral region of the spinal cord that inhibit the motor neurons in Onuf’s nucleus locally and thereby induce relaxation of the sphincter, thus enabling urine flow simultaneously with contraction of the bladder.

Parallel to the corticospinal pathways, the corticonuclear connections travel in the corticonuclear tract, which has also been described as the corticobulbar tract (“bulbus” = former term of the medulla oblongata). The corticonuclear fibers run through the genu of the internal capsule and congregate in the medial cerebral crus, along with the corticospinal fibers. The mesencephalic, pontine and bulbar corticonuclear fibers exert an influence on the cranial nerve nuclei, which control the skeletal musculature (Neuhuber 2004).

Both dorsal column nuclei lie at this level: the gracile nucleus (lower extremities) is located medially, and the cuneate nucleus (upper extremities) laterally. The sensory relay nuclei contain the second neuron of the lemniscal system for touch and proprioception. Their efferent axons cross via the internal arcuate fibers into the medial lemniscus and continue from there to the contralateral thalamus. Laterally, the cuneate nucleus is joined by the external cuneate nucleus, whose neurons carry information from the spinal afferents of the upper extremities to the cerebellum.
