Deep brain stimulation can suppress pathological synchronisation in parkinsonian patients
BACKGROUND Although deep brain stimulation (DBS) of the subthalamic nucleus (STN) is a highly effective therapeutic intervention in severe Parkinson's disease, its mechanism of action remains unclear. One possibility is that DBS suppresses local pathologically synchronised oscillatory activity. METHODS To explore this, the authors recorded from DBS electrodes implanted in the STN of 16 patien...
متن کاملNeonatal influenza infection causes pathological changes in the mouse brain
Influenza A virus infections have been proposed to be associated with a broad spectrum of central nervous system complications that range from acute encephalitis/encephalopathy to neuropsychiatric disorders in humans. In order to study early influenza virus exposure in the brain, we created an influenza-infection model in neonatal mice to investigate infection route and resulting pathological c...
متن کاملPallidal stimulation suppresses pathological dysrhythmia in the parkinsonian motor cortex.
Although there is general consensus that deep brain stimulation (DBS) yields substantial clinical benefit in patients with Parkinson's disease (PD), the therapeutic mechanism of DBS remains a matter of debate. Recent studies demonstrate that DBS targeting the globus pallidus internus (GPi-DBS) suppresses pathological oscillations in firing rate and between-cell spike synchrony in the vicinity o...
متن کاملThe beneficial effect of the flavonoid quercetin on behavioral changes in hemi-Parkinsonian rats
Introduction: A large body of experimental evidence supports a role for oxidative stress as a mediator of nerve cell death in Parkinson's disease (PD). Flavonoids like quercetin have been reported to prevent neuronal degeneration caused by increased oxidative burden, therefore, this study examined whether quercetin administration at a high dose would attenuate behavioral abnormalities in e...
متن کاملPiribedil and pathological gambling in six parkinsonian patients.
UNLABELLED Impulse control disorders (ICD) in Parkinson's disease (PD) have attracted increasing interest. They are characterized by the inability to control the impulse to perform an act that can be detrimental to them or to others. Although dopamine agonists (DA), as a group, have been associated with impulse control disorders (ICD), piribedil has rarely been reported to cause them. METHOD ...
