Area summation in human vision at and above detection threshold
The initial image-processing stages of visual cortex are well suited to a local (patchwise) analysis of the viewed scene. But the world's structures extend over space as textures and surfaces, suggesting the need for spatial integration. Most models of contrast vision fall shy of this process because (i) the weak area summation at detection threshold is attributed to probability summation (PS) ...
متن کاملTemporal summation during extradural anaesthesia.
We have investigated in 10 patients the effect of extradural anaesthesia on temporal summation by comparing pain thresholds to single and repeated (five impulses at 2 Hz) electrical stimuli and compared these tests with pinprick and cold stimulation. Bupivacaine 0.5% (20 ml) was injected at L2-3. After extradural anaesthesia the threshold to repeated stimuli was significantly lower than the thr...

lengths. Fur thermore , Schultz et al. , using artificial membranes with uniformly defined pores, found that for similar Stokes radius the globular proteins have larger reflection coefficients than those of the dextran fractions. Thus, in my opinion, it is erroneous to use the Stokes radius of dextran fractions to correlate the pore size of membranes. Miguel F. Refojo Eye Research Institute Bos...
متن کاملSupra-threshold scaling, temporal summation, and after-sensation: relationships to each other and anxiety/fear
This study investigated the relationship of thermal pain testing from three types of quantitative sensory testing (ie, supra-threshold stimulus response scaling, temporal summation, and after-sensation) at three anatomical sites (ie, upper extremity, lower extremity, and trunk). Pain ratings from these procedures were also compared with common psychological measures previously shown to be relat...
متن کاملVibrotactile temporal summation: probability summation or neural integration?
Temporal summation, a decrease in the detection threshold that occurs when either the duration of a stimulus or the number of stimuli in a sequence is increased, has been attributed to the operations of either the mechanism of neural integration or of probability summation. Our experiments indicate that under certain conditions, both mechanisms may operate, but that the process of neural integr...
