Brain Stem definition: The part of the brain that connects the cerebral hemispheres with the spinal cord. It consists of the MESENCEPHALON; PONS; and MEDULLA OBLONGATA.
brain stem definition: axial portion of the brain exclusive of the cerebellum and the forebrain; includes midbrain, medulla, and pons.
brain stem definition: The part of the brain that is connected to the spinal cord.
Brain Stem definition: The part of the brain that connects the cerebral hemispheres with the spinal cord. It consists of the mesencephalon, pons, and medulla oblongata.
Evoked Potentials, Auditory, Brain Stem definition: Electrical waves in the CEREBRAL CORTEX generated by BRAIN STEM structures in response to auditory click stimuli. These are found to be abnormal in many patients with CEREBELLOPONTINE ANGLE lesions, MULTIPLE SCLEROSIS, or other DEMYELINATING DISEASES.
Auditory Brain Stem Implants definition: Multi-channel hearing devices typically used for patients who have tumors on the COCHLEAR NERVE and are unable to benefit from COCHLEAR IMPLANTS after tumor surgery that severs the cochlear nerve. The device electrically stimulates the nerves of cochlea nucleus in the BRAIN STEM rather than the inner ear as in cochlear implants.
Brain Stem Infarctions definition: Infarctions that occur in the BRAIN STEM which is comprised of the MIDBRAIN; PONS; and MEDULLA OBLONGATA. There are several named syndromes characterized by their distinctive clinical manifestations and specific sites of ischemic injury.
brain stem glioma definition: (glee-O-ma) A tumor located in the part of the brain that connects to the spinal cord (the brain stem). It may grow rapidly or slowly, depending on the grade of the tumor.
Brain Stem Glioma definition: Abnormal growth of the glial cells that comprise the brainstem. This tumor is most easily detected on MRI. The form with the poorest prognosis (median survival of about 12 months) appears to be the diffusely infiltrative pontine lesion. However, it is important to note whether the patient has neurofibromatosis since the literature appears to show a more favorable prognosis for diffuse tumors in patients with neurofibromatosis type I. The dorsally exophytic brainstem lesions has a slightly better expected survival. Brainstem glioma is most commonly found in children. There are preliminary findings in the literature that seem to indicate that adults with brainstem gliomas may have a better survival time. (Kaye AH, Laws ER Brain Tumors Churchill-Livingstone 1995)
brain stem tumor definition: A tumor in the part of the brain that connects to the spinal cord (the brain stem).
