The models in Equations 2 and 3 can then be combined to form a single surface (Figure 5) that captures the stimulus-response relationship in terms of bits of uncertainty.
In order to capture the stimulus processing phase and to separate it from the motor preparation of the response, a delayed response paradigm was used (see Fig. 1a) in the ERP experiment.
In the intersensory presentation then, the auditory stimulus captures the duration of the visual stimuli.
The model, with parameters fit directly to physiological data, simultaneously captures both the stimulus dependence and detailed spatio-temporal correlations in population responses, and provides two insights into the structure of the neural code.
Consequently, to correctly characterize the input-output relationship one needs to use a method that also captures the relationship when dynamic stimuli are present and the responses are dynamic as well.
NS captures a subject's tendency toward exploratory activity and exhilaration in response to novel stimuli, while HA captures the intensity of a subject's response to aversive stimuli and eagerness to avoid such stimuli.
We present a first-principles model for multisensory word recognition that captures the main concepts of a stimulus neighborhood in high-dimensional feature space, where the reliability of the signal affects the size of the neighborhood and lexical information is represented by the distribution of words.
The hazard model provides a good starting point as it is efficient and captures the experimental effects of temporal stimulus parameters.
It is possible that an alternating left-right sound captures the positions of the visual stimuli, resulting in visual motion perception (auditory positional capture) [16], [17].
The latter grouping, referred to here as "high light stimuli," is intended to capture the range of stimuli where even a vitamin A deficient population would be expected to respond [ 7].
