Corneal touch thresholds were measured in 11 people suffering from myasthenia gravis (MG) and in a control group of 20 subjects. The mean threshold in MG was 75.6 mg (SD 52) and in the control group 18.9 mg (SD 7.3); thresholds were thus significantly (p less than 0.01) raised in MG. Although it is not possible to say whether the sensory deficit is due to MG or to the treatment, the results imp...

[Purpose] The aim of this study was to investigate whether neuropathic pain is associated with femoral condylar cartilage thickness, electrical pain threshold, and clinical parameters in patients with knee osteoarthritis. [Subjects and Methods] Sixty patients over the age of 40 diagnosed with knee osteoarthritis were enrolled. The PainDETECT questionnaire, Western Ontario and McMaster Universit...

In this study we evaluated sensory alteration in nasal tip and adjacent upper columella (territory of external nasal nerve) after open rhinoplasty. Two groups were randomly selected, each containing 25 patients with thick nasal skin; sensory testing was done preoperatively in all patients; in group one, subdermal soft tissue in tip and supratip areas was removed but in group two no soft tissue ...

Learning in the marine mollusk Aplysia has been associated with enhanced sensory function, expressed in mechanosensory neurons as (i) decreases in action potential threshold, accommodation, and afterhyperpolarization, and (ii) increases in action potential duration, afterdischarge, and synaptic transmission. These alterations also occur, with a delay, after sensory axons are injured under condi...

given the significance of relativism in molding our worldview and uncovering the nature of truth, this study using the newly-developed concept of emotioncy, attempted to introduce sensory relativism as a new perspective based on which senses can relativize our understanding of the world. to espouse the theory, 24 individuals were interviewed on their experiences of phlebotomy. the results were ...

The eyes of Rhesus monkeys were exposed to an argon laser operating at 5,145 A. Retinal exposure sites were examined with ophthalmoscopic and histopathologic techniques. The retinal damage threshold was determined ophthalmoscopically for exposure durations of 12, 70, 125, and 1,000 msec. The utilization of flat preparations of the pigment epithelium and sensory layers of the retina proved to be...

Motivated by the natural representation of stimuli in sensory systems, we investigate the representation of a bandlimited signal by an ensemble of Hodgkin–Huxley neurons with multiplicative coupling. We show that such a neuronal ensemble is I/O equivalent with an ensemble of integrate-and-fire neurons with variable threshold. The value of the threshold sequence is explicitly given. We describe ...

Results: The peak vibration frequency was about 150 Hz irrespective of vibration intensity, which would effectively activate fast adapting type II (FAII) cutaneous mechanical receptors. The two-point discrimination threshold measured at the third pad of the index finger decreased significantly when a near-threshold vibrotactile stimulus was applied to the dorsal hand, a response termed stochast...
