41 Despite decades of research devoted to the study of inferior colliculus (IC) neurons’ tuning to 42 sound-source azimuth, there remain many unanswered questions because no previous study examined 43 azimuth tuning over a full range of 360° azimuths at a wide range of stimulus levels in an unanesthetized 44 preparation. Furthermore, a comparison of azimuth tuning to binaural and contralateral-...

It has been demonstrated previously that transcranial magnetic stimulation (TMS) of the sensorimotor cortex can induce transient suppression of the perception of cutaneous near-threshold stimuli from fingers of the contralateral hand in normal individuals. One explanation accounting for deficits in the exploration of contralateral space following a unilateral hemispheric lesion refers to a loss...

background: to reduce the dose to normal tissues surrounding the treated breast, a uniform magnetic field was used within a humanoid phantom in breast radiotherapy. materials and methods: monte carlo simulations were performed with geant4, irradiating humanoid phantoms in a magnetic field. to reconstruct phantoms, computed tomography (ct) data slices of four patients were used for the monte car...

The centre médian-parafascicular (CM-Pf) complex is located at the posterior intralaminar nuclei of the thalamus and forms part of the nonspecific thalamocortical projection system and the internal circuit of the basal ganglia. However, the functional roles of this complex remain to be fully elucidated. Here we have examined whether the CM-Pf complex is involved in the process of covert attenti...

1. The acute effect of diazoxide (150-300 mg, intravenously) on renal venous renin has been evaluated in forty-four patients with suspected renal hypertension. 2. In twenty-seven studies which showed no lateralization, diazoxide raised the mean peripheral renin to 175% of control (P less than 0-05) but the renal vein renin ratio showed an insignificant change (1-15 to 1-21). 3. In seventeen stu...
