There is controversy over how hormonal conditions influence cerebral physiology. We studied pattern-shift visual evoked potentials (PS-VEP), brain stem auditory evoked potentials (BAEP) and short-latency somatosensory evoked potentials (SSEV) in 20 female volunteers at different phases of the menstrual cycle (estrogen phase, ovulatory day and progesterone phase). Statistical analysis showed dec...

BACKGROUND Although acupuncture is effective for treating several conditions, its site specificity is questionable. OBJECTIVE To investigate whether acupuncture influences the brainstem auditory evoked potentials (BAEP). METHODS 10 healthy volunteers were enrolled according to inclusion criteria. One of four acupuncture points-TE3, GB43 (both auditory system-specific, according to tradition...

Cerebellopontine angle tumors including schwannoma or meningioma are located around the vestibular nerve. In case of surgical removal, intraoperative neurophysiologic monitoring (IONM) modality such as brainstem auditory evoked potential (BAEP) could detect its neurologic function. We demonstrate 2 cases cerebellopontine surgery using BAEP an IONM modality. And we also suggest how to deal with ...

P300, somatosensory evoked potential (SEP) and brainstem auditory evoked potential (BAEP) are widely used neurophysiological methods for objectively evaluating cognitive, somatosensory and brainstem auditory functions. We studied the P300, SEP and BAEP in 17 patients with chronic respiratory insufficiency (PaO2:58.2 +/- 7.0 mmHg; mean +/- SD) and 15 age-matched healthy subjects (PaO2: 84.4 +/- ...

COPD is a disease characterized by airflow limitation and is not fully reversible. Cigarette smoke can induce inflammation and directly damage the lungs. It is a major public health problem and currently fourth leading cause of death worldwide. COPD includes emphysema and chronic bronchitis. Auditory brainstem response (ABR) is a click stimulus that generates a response from the hair cells of t...

A 48-year-old woman with a Ramsay Hunt syndrome due to herpes zoster had a hearing deficit. Brainstem auditory evoked potentials (BAEPs) localised the site of dysfunction to the ipsilateral eighth nerve. Clinical improvement was associated with improvement of the BAEP. Conventional audiological studies and BAEPs provided no evidence of involvement of the cochlea or the brainstem. In Ramsay Hunt...

BACKGROUND Neuraxial anaesthesia produces a sedative and anaesthetic-sparing effect. Recent evidence suggests that spinal cord anaesthesia modifies reticulo-thalamo-cortical arousal by decreasing afferent sensory transmission. We hypothesized that epidural anaesthesia produces sensory deafferentation-dependent sedation that is associated with impairment of brainstem transmission. We used brains...

We aimed to evaluate structure and functions of central nervous system (CNS) in children with glycogen storage disease (GSD) type 1a. Neurological examination, psychometric tests, electroencephalography (EEG), magnetic resonance imaging (MRI), visual evoked potentials (VEP) and brainstem auditory evoked potentials (BAEP) were performed. The results were compared between patients with good and p...

Brainstem auditory evoked potentials (BAEP) were recorded in two patients with nasopharyngeal carcinoma (NPC) irradiated 14 and three years ago respectively and compared with 15 healthy controls. The patients had features of post-irradiation myelopathy of the brainstem with reduced gag reflex, unilateral vocal cord paralysis and fasciculation of the tongue. The first patient had a blind left ey...

The Brainstem Auditory Evoked Potentials (BAEP) are signals calculated from the EEG signals registered as responses to an acoustic activation of the auditory system. The BAEP signals provide an objective, electrophysiological diagnostic method, widely applied in examinations of auditory organs, in particular for such cases, when the application of traditional audiometric methods is difficult or...
