Brainstem reflexes and brainstem auditory evoked responses in Huntington's chorea.
Blink reflex, corneal reflex, jaw reflex, exteroceptive suppression in masseter muscles and brainstem auditory evoked potentials were measured in 20 patients with Huntington's chorea and 12 controls. A significantly increased latency of the second component of the homolateral and heterolateral blink reflex was found in the patient group as compared with the controls. The other investigations re...
متن کاملNeurophysiological studies SPINAL CORD AND BRAINSTEM REFLEXES
It took decades to accept that dystonia, a bizarre condition which often produces abnormal movements exclusively during specific activities like writing, was due to brain disease. Clinical neurophysiology certainly added to this evolution of thinking. Recent neurophysiological observations demonstrate that dystonia is not only due to an isolated brain motor dysfunction, but also to sensory and ...
متن کاملA brainstem network mediating apneic reflexes in the rat.
Apnea is an important protective response to upper airway irritation, but the central mechanisms responsible for eliciting sensory-induced apnea are not well understood. Recent studies have emphasized the Kölliker-Fuse nucleus in producing apnea and proposed a trigeminoparabrachial pathway for mediating these reflexes. However, in our earlier study of apneic responses produced by glutamate stim...
متن کاملInhibitory brainstem reflexes under external emotional-stimuli in bipolar I and II disorders
BACKGROUND Bipolar disorder types I (BD I) and II (BD II) might present different dysfunctions of the cortex and brainstem, as reflected by the second exteroceptive suppression period of temporalis muscle activity (ES2) under different stimuli of external emotions. METHODS This study included 30 BD I and 20 BD II patients, and 40 healthy volunteers. All participants were invited to answer the...
متن کاملHyperekplexia and stiff-man syndrome: abnormal brainstem reflexes suggest a physiological relationship.
BACKGROUND AND OBJECTIVES Hyperekplexia and the stiff-man syndrome (SMS) are both conditions with exaggerated startle suggesting abnormal brainstem function. Investigation of brainstem reflexes may provide insight into disturbed reflex excitation and inhibition underlying these movement disorders. PATIENTS AND METHODS Using four-channel EMG, we examined four trigeminal brainstem reflexes (mon...
