PURPOSE To test the hypothesis that variability of conventional automated perimetry can be reduced using size V stimuli for patients with glaucomatous visual field damage. METHODS Ten patients with glaucoma and five age-matched control volunteers were tested with the Humphrey Field Analyzer program 24-2 or 30-2, after which the method of constant stimuli was used to measure frequency-of-seein...

the amygdala is a forebrain region, which is known as a modulator of pain sensation. the amygdala, particularly the central nucleus, has high concentrations of enkephalins relative to dynorphins and has high concentrations of opioid receptors. we here studied the role of central nuclei of amygdala in morphine antinociception. methods: in this study, we used 130 male wistar rats (200- 250g). bil...

Salient stimuli presented at unattended locations are not always perceived, a phenomenon termed inattentional blindness. We hypothesized that inattentional blindness may be mediated by attentional inhibition. It has been shown that attentional inhibition effects are maximal near an attended location. If our hypothesis is correct, inattentional blindness effects should similarly be maximal near ...

PURPOSE When individuals with central vision loss due to macular degeneration (MD) view stimuli in the periphery, most of them activate the region of retinotopic cortex normally activated only by foveal stimuli-a process often referred to as reorganization. Why do some show this reorganization of visual processing whereas others do not? We reported previously that six individuals with complete ...

Introduction: Central nervous system factors are now understood to be important in the etiology of temporomandibular disorders (TMD), but knowledge concerning objective markers of central pathophysiology in TMD is lacking. Multivariate analysis techniques like support vectormachines (SVMs) could generate important discoveries regarding the expression of pain centralization in TMD. Support vecto...

Imagine having to prove everything you believe at one time. That is exactly what happened when I was asked to change the design of an Enterprise Backup System to accommodate the backup and restore needs of a new, very large system. To meet the challenge, I’d have to use three brand-new pieces of technology and push my chosen backup software to its limits. Would I be able to send that much data ...

CSF findings resemble those in other infections of the central nervous system. Appearance of a focal neurological deficit in a case of TBM should suggest secondary neurovascular impairment, even in patients who are receiving appropriate treatment. Nevertheless, as this case description shows, a cerebral infarct with an atypical location may be a form of presentation of TBM, which should be cons...
