Most commonly the sixth nerve is affected resulting in lateral rectus palsy due to its relatively longer course of exposure as it ascends from the pontomedullary
junction to the petrous apex and Dorello's canal.
Primary Neuronal Injuries;-Cortical contusions, Diffuse axonal injury, Subcortical grey matter injury, Primary brainstem injury (DAI, direct laceration, pontomedullary
AEP responses (particularly the absolute and interpeak latencies) represent a series of potentials corresponding to sequential activation of the peripheral (acoustic nerve and pontomedullary
portion) and central (pontine and midbrain) portions.
10-11) The pontomedullary
reticular formation receives nearly 90% of the output dedicated to the neuraxis and cortex modulation, ipsilaterally.
010), leading the authors to suggest the involvement of degeneration of the pontomedullary
respiratory centers in the development of PD-linked EDS.
Passes ventrally to leave the brainstem at the pontomedullary
junction, just lateral to the pyramidal prominence.
MRI sequences performed (including sagittal T1, sagittal T2 and axial T2-weighted sequences) demonstrated the REH compressing the pontomedullary
junction of the brainstem.
43,44 The C1(Ad) nuclei exchanges inhibitory axons with A5(NA) pontomedullary
nucleus, which is responsible for neural sympathetic activity.
The differential diagnosis of an abnormal localized signal intensity in the olive and pontomedullary
area includes ischemic infarction, demyelination, tumor, an inflammatory process (including sarcoidosis), and focal rhomboencephalitis.
Locomotion produced in mesencephalic cats by injections of putative transmitter substances and antagonists into the medial reticular formation and the pontomedullary
Damage to the descending inputs to the pontomedullary
area once referred to as the faciorespiratory center is most likely to result in release of bulbar function and, subsequently, involuntary emotional expression disorder (IEED).
neuronal networks are involved in the regulation of muscle tone.
