Probability Summation over Time
The sensory rcsponse lo ligltl persists in lime. This fact obliges us to ui'n.ierst:ind how the temporally distrihuted effects of visual slimukition collectively determine thrcshokl, A cl;tssieiiI solution to this problem has been to supposc lh;il the eye integrates the light sis,n;il ovrr somc inlcrviil of timc, the criliciil durcition.

متن کاملMeasures of multisensory integration based on dependent probability summation: from spike counts to reaction times
A single neuron is categorized as “multisensory” if there is a statistically significant difference between the response evoked by a cross-modal stimulus combination and that evoked by the most effective of its components individually. The most widely applied quantitative index expresses multisensory enhancement (or inhibition) as a proportion of the strongest unisensory response. However, it h...
متن کاملQuantification of binaural loudness summation by measuring simple reaction time
When listening to sounds in a natural environment, different sound pressure levels reach the two ears. They are nevertheless combined to result in a single ’binaural’ loudness. This phenomenon is called binaural loudness summation. In the laboratory it can be carried to an extreme by stimulating one ear only (monaural presentation) or both ears (binaural or diotic presentation) using headphones...
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...
متن کاملThe Comparison of Working Memory and Reaction Time in Non-Athlete, Athlete and Heroin-Dependent Individuals *
Objective: The aim of this study was to compare memory working and semantic strop in non-athlete, athlete and heroin-dependent individuals. Method: The present study was a causal-comparative study. Forty-five men were selected by convenience sampling and divided into three groups: non-athlete, athlete, and heroin-dependent individuals. Participants were assessed using neuropsychological instrum...
