BACKGROUND Polypharmacy and inappropriate medication prescriptions are associated with increased morbidity and mortality. Most interventions proposed to improve appropriate prescribing are time and resource intensive and therefore hardly applicable in daily clinical practice. OBJECTIVE To test the efficacy of an easy-to-use checklist aimed at supporting the therapeutic reasoning of physicians...

The reduction in symptoms of Parkinson's disease produced by high-frequency stimulation (HFS) in the internal globus pallidus (GPi) has been proposed to be due to stimulus-induced inactivation of pallidal neurons and resulting disinhibition of thalamic neurons. We tested this in awake Macaca fascicularis by stimulating between pairs of electrodes inserted into GPi under electrophysiological con...

The present experiment was concerned with some discharge properties of single neurons in the medial geniculate body of the locally anesthetized paralyzed cat. The effect of pairing clicks with paw shock upon discharge rate and pattern was of particular concern. Twelve neurons obtained from 11 cats were studied exhaustively for periods up to 4 hr. Under control conditions, rate stationarity for ...

A model of the self-discharge process of a nickel-hydrogen cell is presented. The model includes three electrochemical reactions on the nickel electrode (reduction of nickel oxyhydroxide, oxidation of hydrogen, and oxidation of hydroxyl ion to form oxygen) and two electrochemical reactions on the hydrogen electrode (reduction of oxygen and oxidation of hydrogen). The self-discharge pressure pro...

This study aimed to define the acute electrophysiological effects of the perilymphatic perfusion of streptomycin in the sensory apparatus of the semicircular canals of the frog. The ampullary DC potential, the vestibular nerve multiunit discharge, the nerve DC potential and the unitary EPSP activity were recorded in isolated semicircular canals of the frog (Rana esculenta L). The results demons...
