Posturographic studies on healthy young subjects indicate a reduction of stability during stance with head extension when compared to direct head position (Jaskson and Epstein, 1991). However, some patients with peripheral vestibular deficit improve postural stability during stance with head extension when comparing to stance with direct head position (Norris, 1995). Based on these data, we included stance with head extension to our posturographic examination. We compared measurements in stance with head extended (Ex) with parameters measured during the stance with direct head position (Pr). Both situations measured with eyes closed to eliminate the influence of visual information. For comparison of individual par...

Polysomnographic recording enabled to make distinction between different sleep stages, and on this basis, the criteria for different sleep disorders including narcolepsy came into being. The main feature of narcolepsy rests in increased REM sleep penetration verified by the multiple sleep latency test (MSLT). In clinical terms, the disease is marked by imperative attacks of daytime sleep and usually also by cataplexy – sudden loss of muscle tone evoked by emotive experience. The first indication of the immunogenetic basis of narcolepsy came with the discovery of its link to the HLA-DR2 (15) subgroup and with the subsequently revealed connection between narcolepsy–cataplexy and...

Recent findings of unconditioned blink reflex alterations, as well as changes in blink reflex modulation by subthreshold prepulse stimuli or suprathreshold double pulse stimulation, in patients with spinal cord injury or chronic pain syndromes, e.g. fibromyalgia, suggest plastic changes at the brainstem level in these conditions. The blink reflex and its modulation also serve to document acute pharmacological effects, e.g. following intrathecal bolus application of the GABA-ergic drug baclofen, thus concurring with an antispastic action of baclofen at the brainstem level.

A fundamental but still not sufficiently solved question is how to improve disability after stroke. One approach to this unmet medical need is to explore ways of modifying synaptic plasticity and learning along a translational pathway from basic neuroscience over healthy human subjects to stroke patients [Ziemann et al. 2006, Neurorehabil Neural Repair; 20: 243–51]. This presentation will review evidence for this translational pathway on how pharmacological treatment or brain stimulation modulates synaptic plasticity (long-term plasticity, LTP) and motor learning, which is thought to be an LTP-dependent process.

Recent evidence shows a prominent theta (4–7Hz) rhythm in the PPN (Tsang et al., Neurology, 2010; Simon et al., J. Neurophysiol., 2010; Shimamoto et al., JNNP, 2010). Given that theta activity is modulated by vestibular signals elsewhere in the brain, e.g. hippocampus, (Shin, Synapse, 2010; Chen et al., Neuroimage, 2010), we assessed whether vestibular signals modulate PPN theta activity.

It is believed that TCR is mediated by polysynaptic brainstem neuronal pathways including trigeminal afferents, trigeminal nuclei and motor neurons of neck muscles. In an attempt to increase our knowledge about the mechanism and alteration of TCR, we studied the trigemino-cervical reflex and the conventional blink reflex (BR) in neurobehcet (NB), multiple sclerosis (MS), and ischemic stroke patients with brainstem involvement. We also recorded the blink reflex to study the association between two different trigeminal reflexes.

In focal tasks, excitation is increased in the muscles expected to react and decreased in others such as, for instance, the homonymous muscles of the contralateral side. The contrast between the increase and decrease of excitability in homonymous muscles is likely much more marked in SRT than in CRT. We reasoned that, if inhibition is not fully accomplished, some remaining activity would be seen in the muscles not to be responding in a StartReact paradigm using SRT and CRT.

In limb muscles, this is studied using the short afferent inhibition (SAI) paradigm, to assess sensorimotor interaction, and paired associative stimulation (PAS), to evaluate LTP-like plasticity. As far as we know, SAI and PAS paradigms have never been used in the territory of the cranial nerves. The present study was aimed at testing in normal subjects whether sensorimotor interaction and LTP-like plasticity can be observed in facial muscles as well as in limb muscles.

In healthy subjects, a single-pulse TMS induces two facilitatory phases of the soleus H-reflex: one at inter-stimulus intervals (ISI) between 5 and 30ms and the other at ISIs between 80 and 110ms. The first facilitatory phase is supposed to be due to summation of the excitatory input from the descending excitatory postsynaptic potentials (EPSP) generated by TMS and the Ia-afferents, while the mechanisms responsible for the second phase are less clear. To further investigate these mechanisms, we evaluated in 13 healthy subjects how the soleus H-reflex was modulated by conditioning single pulse TMS at ISIs from 0...

Primary progressive freezing of gait (PPFOG) manifests predominantly as progressive freezing gait and difficulties of writing or speaking without accompanying any other movement disorders. Although FOG is mostly associated with PSP, some authors proposed that PPFOG is a distinct clinical and pathophysiological entity. Previous studies showed that startle response is absent or TCR is abnormal in most PSP patients, and its measurement has been proposed as a method of distinguishing PSP from other Parkinsonian disorders. On the other hand, startle response was found to be exaggerated in PPFOG. Based on those previous observations we aimed to investigate the characteristics of brainstem reflexes in PPFOG ...

For proficiency subjects may use programmed movements to be done following an external command. Voluntary reactions can be speeded up by a startling auditory stimulus (SAS) delivered at the same time as the imperative signal, a phenomenon termed StartReact (Valls-Solé et al., 1995). It is unknown if tasks requiring a precise endpoint can also be affected by SAS. The aim of the present study is to examine how a task that requires a precise endpoint responds to a SAS delivered at different timings during the task.

These results may reflect adaptation to impulses load carried by median axons that would be far greater with a higher frequency.

In these studies, the MMN was usually elicited by employing occasional frequency, duration or speech-sound changes in repetitive background stimulation while the patient was reading or watching videos. It was found that in a large number of different neuropsychiatric, neurological and neurodevelopmental disorders, as well as in normal ageing, the MMN amplitude was attenuated and peak latency prolonged. Besides indexing decreased discrimination accuracy, these effects may also reflect, depending on the s...

The lateralization of the upper and lower extremity motor representation demonstrates reorganization after insults to the affected hemispheres of both diplegic and hemiplegic children. SIGNIFICANCE: The current study is a step towards defining the relationship between changes in motor maps and functional impairments in CP. These results suggest the need for further work to develop improved classification schemes that integrate clinical, radiologic, and neurophysiologic measures in CP.

As a consequence, the hyperexcitability of facial nerve generates spasms on the facial muscles. Microvascular decompression (MVD) of the facial nerve near its REZ has been established as an effective treatment of HFS. Intra-operative disappearance of abnormal muscle responses (lateral spread) elicited by stimulating one of the facial nerve branches has been used as a method to predict MVD effectiveness.

However, the device, in its current form, may be less accurate during rapid movements when inertia contributes to stiffness and the shape of the air-filled pads did not provide a good interface with the foot.

It mostly affects elderly citizens, especially post...

Neurophysiological techniques are likely the best suited of all paraclinical tests for documenting the eventual excitability changes that may occur in certain physiological states and in many neurological disorders. The best known test of brainstem excita...

This effect can be attributed, in part, to shortening the stimulation duration.Significance: After SCI, increasing the baseline temperature for CHEPs in dermatomes with absent or diminished sensation improved the neurophysiological resolution of afferent sparing.

This method also eliminates the false positive and negative reports caused by using a single reference table for all heights. SIGNIFICANCE: A unique reference table can be produced using the Fmin/He or Fmin/L for all populations and races, so that the comparison between different population samples can be done easily. Also data of different investigations can be pooled together for meta-analysis purposes when a single reference table is used for different samples.
