Alterations in local cerebral glucose utilisation in specific thalamic nuclei following apomorphine.
The alterations in local cerebral glucose utilisation in eight discrete nuclei in the thalamus following the administration of apomorphine (0.5 mg kg-1) have been investigated with the autoradiographic 2-deoxyglucose technique in 11 conscious rats. In two thalamic nuclei (parafascicular and ventrolateral nuclei), glucose utilisation was significantly elevated following apomorphine; in two thala...
This case study followed one adolescent patient who underwent bilateral deep brain stimulation of the centromedian parafascicular complex (CM-Pf) for debilitating, treatment refractory Tourette's syndrome for a period of 1.5 years. Neurocognitive testing showed no significant changes between baseline and follow-up assessments. Psychiatric assessment revealed positive outcomes in overall adaptiv...
In this prospective double blind randomised "N of 1" study, a patient with a severe form of Tourette's syndrome was treated with bilateral high frequency stimulation of the centromedian-parafascicular complex (Ce-Pf) of the thalamus, the internal part of the globus pallidus (GPi), or both. Stimulation of either target improved tic severity by 70%, markedly ameliorated coprolalia, and eliminated...
introduction: the antinociceptive effect of morphine is, in part, mediated through the activation of a descending pathway. one of the major components of this pathway is the nucleus raphe magnus (nrm). our previous study demonstrated the involvement of nrm in the analgesic effect of morphine microinjected into the nucleus cuneiformis (ncf) in a descending manner. the aim of the current study wa...
a b s t r a c tintroduction: the nucleus cuneiformis (ncf) and ventrolateral periaqueductal gray (vlpag), two adjacent areas, mediate the central pain modulation and project to the nucleus raphe magnus (nrm). methods: this study examined whether the antinociceptive effect of morphine microinjected into the ncf is influenced by inactivation of vlpag and nrm in rats. animals were bilaterally micr...
BACKGROUND Conventional approaches to deep-seated cerebral lesions range from biopsy to transcortical or transcallosal resection. Although the former does not reduce tumor burden, the latter are more invasive and associated with greater potential for irreparable injury to normal brain. Disconnection syndrome, hemiparesis, hemianesthesia, or aphasia is not uncommon after such surgery, especially...
PURPOSE The aim of this study was to investigate whether the nucleus parafascicularis (Pf) of the thalamus could be a relay of the control of epileptic seizures by the superior colliculus (SC). The Pf is one of the main ascending projections of the SC, the disinhibition of which has been shown to suppress seizures in different animal models and has been proposed as the main relay of the nigral ...
The projection from the thalamic centre médian-parafascicular (CM-Pf) complex to the caudate nucleus and putamen forms a massive striatal input system in primates. We examined the activity of 118 neurons in the CM and 62 neurons in the Pf nuclei of the thalamus and 310 tonically active neurons (TANs) in the striatum in awake behaving macaque monkeys and analyzed the effects of pharmacologic ina...
