13. Palmaris brevis spasm syndrome.
Palmaris brevis spasm syndrome is a rare and benign condition of localised muscular hyperactivity. In five men, the hypothenar eminence underwent spontaneous, irregular, tonic contractions of the palmaris brevis muscle. An EMG showed spontaneous high frequency discharges of normal motor units, without evidence of neuropathy or of nerve compression. This synd

14. Simple tics in Gilles de la Tourette's syndrome are not prefaced by a normal premovement EEG potential.
EEG events prior to simple tics have been examined in six patients with Gilles de la Tourette's syndrome, and compared to EEG changes occurring when the same subjects voluntarily mimicked their own tics. Voluntary jerks were prefaced by a premovement negative potential commencing about 500 ms prior to the muscle EMG discharge and reaching an amplitude of abo

15. Identifying Adverse Drug Events: Development of a Computer-based Monitor and Comparison with Chart Review and Stimulated Voluntary Report
Abstract Background: Adverse drug events (ADEs) are both common and costly. Most hospitals identify ADEs using spontaneous reporting, but this approach lacks sensitivity; chart review identifies more events but is expensive. Computer-based approaches to ADE identification appear promising, but they have not been directly compared with chart review and th

16. Readiness potential of cortical area 6 preceding self paced movement in Parkinson's disease.
The vertex Readiness Potential (RP) (Bereitschaftspotential) preceding self paced voluntary movements is reduced in duration and amplitude in patients with Parkinsonism. It cannot be used as an index for delayed initiation of movement. The negative potential is commonly replaced by a positive slow wave. In hemi-Parkinsonism, the abnormal RP is more apparent

17. Tuning pacemaker frequency of individual dopaminergic neurons by Kv4.3L and KChip3.1 transcription
The activity of dopaminergic (DA) substantia nigra (SN) neurons is essential for voluntary movement control. An intrinsic pacemaker in DA SN neurons generates their tonic spontaneous activity, which triggers dopamine release. We show here, by combining multiplex and quantitative real-time single-cell RT– PCR with slice patch–clamp electrophysiology, that

18. Efferent discharges recorded from single skeletomotor and fusimotor fibres in man.
Experiments were performed on awake human subjects in which single nerve fibre activity was recorded in the lateral peroneal nerve using tungsten micro-electrodes as described by Hagbarth & Vallbo (1967, 1968a). The discharge of twelve single efferent fibres innervating the tibialis anterior muscle (t.a.) or the extensor digitorum longus muscle (e.d.l.) was

19. The stiff leg syndrome.
Four patients had a chronic progressive disorder beginning in middle age and involving stiffness and painful spasms of the lower limbs. Spasms were spontaneous, reflex, and induced by voluntary movement. Patients had rigidity and abnormal postures of one or both legs. There was no truncal rigidity or exaggerated lumbar lordosis. Despite the presence of sympt

20. Respiratory modulation of muscle sympathetic and vagal cardiac outflow in man.
We studied the influence of respiration on muscle sympathetic and cardiac vagal activities in twenty conscious, healthy young adult subjects. Efferent post-ganglionic muscle sympathetic activity was measured directly with electrodes inserted percutaneously into a peroneal nerve, and vagal cardiac activity was measured indirectly from electrocardiographic cha

21. Fas ligand is not only expressed in immune privileged human organs but is also coexpressed with Fas in various epithelial tissues.
AIMS: To confirm the recent data obtained in mice, showing that the Fas ligand (FasL) is involved in the phenomenon of "immune privilege" (the apparent defect of the immune system in specific anatomical sites) and to extend this finding to humans. METHODS: The expression of FasL was analysed in a panel of histologically normal human tissues by reverse transc

22. Origins of Abnormal Excitability in Biceps Brachii Motoneurons of Spastic-Paretic Stroke Survivors
Stroke survivors often exhibit abnormal motoneuron excitability, manifested clinically as spasticity with exaggerated stretch reflexes in resting muscles. We examined whether this abnormal excitability is a result of increased activation of intrinsic voltage-dependent persistent inward currents (PICs) or whether it is a result of enhanced synaptic inputs to
