conclusions the assr can accurately predict the degree and configuration of hearing loss and discriminate the normal hearing from mild or moderate hearing loss and mild from moderate hearing loss, except for 500 hz. the air-conducted assr could not define the type of hearing loss. results the assr accurately estimates the behavioral thresholds as well as flat and sloping configurations. there w...

objective(s):previous studies demonstrated a functional similarity between vertebrate and honey bee nervous systems. the aim of the present study was to compare the effects of heroin and iranian street kerack, a combination of heroin and caffeine, on sensory threshold and locomotor activity in honey bees. materials and methods: all drugs were given orally to honey bees 30 min before each experi...

objective: to investigate the correlation between lower and higher order sensory functions and manual dexterity as well as to identify the sensory measures that could predict manual dexterity in patients with idiopathic parkinson’s disease (pd). materials and methods: in this cross-sectional study, 55 patients with idiopathic pd by mean age of 59.85 ± 11.89 years, and mean hoehn and yahr stage ...

W e read with much interest the recent study by Sosenko et al. (1). Studies that screen for both NIDDM and polyneuropathy in subjects without a history of glucose intolerance are rare and therefore welcome. In general , their cross-sectional data agree very well with our findings in a general Cau-casian population. We also found that vibration threshold is related to glycemic level, controlling...

processes underlying sensory discrimination. Simply stated, the question is whether, under a particular set of conditions, sensation is changed in a continuous or a discrete manner as the corresponding physical stimulus is continuously altered. Evidence on the issue is typically obtained in experiments on differential thresholds. Stevens (1) contends that "some 140" functions have been obtained...

Differences in sensory function between young (n = 42, 18-31 years old) and older (n = 137, 60-88 years old) adults were examined for auditory, visual, and tactile measures of threshold sensitivity and temporal acuity (gap-detection threshold). For all but one of the psychophysical measures (visual gap detection), multiple measures were obtained at different stimulus frequencies for each modali...
