摘要： Sixty-eight patients with typical carpal tunnel syndrome underwent neurophysiological investigations preoperatively, but these were not assessed until the end of the study. Open carpal tunnel release was performed and the clinical diagnosis of carpel tunnel syndrome was considered as confirmed when there was a prompt resolution of the preoperative symptoms. Sixty-three of the 68 patients responded well to surgery, three had equivocal outcomes and two did not improve, and thus were considered not to have carpal tunnel syndrome, The neurophysiological tests were normal in these two patients, but were also normal in 14 of the 63 patients who improved with carpal tunnel surgery. Preoperative neurophysiology might therefore have led to up to 14 of the 63 cases of carpal tunnel syndrome being turned down for surgery. We conclude that neurophysiological studies contribute little to the diagnosis in typical cases of carpal tunnel syndrome, and are more often confounding than of assistance.

摘要： A recent neurophysical model of propagation of electrical waves in the cortex is extended to include a physiologically motivated subcortical feedback loop via the thalamus. The electroencephalographic spectrum when the system is driven by white noise is then calculated analytically in terms of physiological parameters, including the effects of filtering of signals by the cerebrospinal fluid, skull, and scalp. The spectral power at low frequencies is found to vary as f−1 when awake and f−3 when asleep, with a breakpoint to a steeper power-law tail at frequencies above about 20 Hz in both cases; the f−1 range concurs with recent magnetoencephalographic observations of such a regime. Parameter sensitivities are explored, enabling a model with fewer free parameters to be proposed, and showing that spectra predicted for physiologically reasonable parameter values strongly resemble those observed in the laboratory. Alpha and beta peaks seen near 10 Hz and twice that frequency, respectively, in the relaxed wakeful state are generated via subcortical feedback in this model, thereby leading to predictions of their frequencies in terms of physiological parameters, and of correlations in their occurrence. Subcortical feedback is also predicted to be responsible for production of anticorrelated peaks in deep sleep states that correspond to the occurrence of theta rhythm at around half the alpha frequency and sleep spindles at 3/2 times the alpha frequency. An additional positively correlated waking peak near three times the alpha frequency is also predicted and tentatively observed, as are two new types of sleep spindle near 5/2 and 7/2 times the alpha frequency, and anticorrelated with alpha. These results provide a theoretical basis for the conventional division of EEG spectra into frequency bands, but imply that the exact bounds of these bands depend on the individual. Three types of potential instability are found: one at zero frequency, another in the theta band at around

摘要： INTRODUCTION All living organisms seek to maintain their survivalin the presence of both extrinsic and intrinsic *** successful, these organisms can be said to be inhomeostasis-an harmonious state born of an extremelycomplexified equilibrium. The harmony achieved is con-stantly challenged often to the point of threat. Survivalthrough successful adaptation is maintained by adapta-tional responses balancing an huge array of biological,psychological and sociological behaviors. The broadspectrum of stimuli capable of engaging the stress-response neuroendocrine system reflects how well inte-grated our perceptions of the physical and psychologicalworlds needs to be. In this context clinically signifi-cant stress can be understood as a state of disharmony orthreatened homeostasis. Biochemical, physiological,
