Historically, brainstem gliomas have been considered as a single entity. Since the introduction of magnetic resonance (MR) imaging in the late 1980s, these tumors are now regarded as a heterogeneous group of neoplasms with different age of onset, clinical and radiologic presentation, and varying behavior and natural history.

Consciousness and the brainstem
Cognition, 2001In the first part of this article we summarize a theoretical framework and a set of hypotheses aimed at accounting for consciousness in neurobiological terms. The basic form of consciousness, core consciousness is placed in the context of life regulation; it is seen as yet another level of biological processing aimed at ensuring the homeostatic balance

Clinical Electroencephalography, 1985
A patient with the clinical picture of brain death resulting from brainstem hemorrhage and subsequent infarction is presented. The EEG showed activity similar to what has been described in the cerveau isolé animal preparations. Cortical evoked potentials were unobtainable from auditory or somatosensory stimulation, but of unusually high amplitude to ...

Magnetic resonance imaging (MRI) is the most sensitive imaging technique for assessing brainstem involvement in neurodegenerative diseases. An MRI can assess the degree of atrophy of the brainstem and alterations in signal intensity on T2-weighted images in the affected areas, which are the main imaging findings found in these diseases.

Cochlear and brainstem implantation
Otolaryngologic Clinics of North America, 2002Cochlear implantation is an established habilitative and rehabilitative option for profoundly deafened individuals over 1 year of age who derive limited benefit from conventional hearing aids. Auditory performance varies among individuals and is determined primarily by age at implantation, pre-existence of speech and language skills, and the time ...

Journal of Clinical Neurophysiology, 2013
The complex neuroanatomy of the brainstem and the additional distortion incurred by intrinsic lesions have previously discouraged aggressive neurosurgical procedures. Safe access to the brainstem and complete lesionectomy has been thwarted by considerable perioperative risk.

Cerebellar and Brainstem Malformations
Neuroimaging Clinics of North America, 2016The frequency and importance of the evaluation of the posterior fossa have increased significantly over the past 20 years owing to advances in neuroimaging. Conventional and advanced neuroimaging techniques allow detailed evaluation of the complex anatomic structures within the posterior fossa.

Abstract The brainstem is the lowermost, stalk-like part of the brain. Phylogenetically it is the oldest part of the human brain, similar in structure and function to the brains of reptiles and fish. The brainstem controls basic functions necessary for physiologic survival, such as heart rate, breathing, and digestion, as well as sleep ...
