English letters (a, b, c, or d) are presented to the right ears of the subjects, and they have to push "H" when they register stimulus a, "J" for b, "K" for c, and "L" for d.
The subjects have to push "S" on the keyboard when they register stimulus 1, "D" for 2, "F" for 3, and "G" for 4. For the visual stimuli, the subjects have to push "H" for the leftmost stimulus, "J" for the stimulus immediately after the first, then "K" and "L" for the last two stimuli.
Robots' core elements include sensors that transmit signals to register stimuli, actuators that convert energy into motion, and software that controls actions.
So neural delays — from registering a stimulus all the way to the physical response — can be potentially costly.
The discrepancy in results between both tasks may lie in the suggestion that Baseline Speed may have required some form of cognitive processing (i.e. registering a stimulus and responding to it), whereas Tapping only required executing a motor action.
If no response was registered, the stimulus disappeared automatically after 3,000 ms.
Thus, in contrast to mere registering the physical stimulus change, the activity around 200 ms the difference waves is most likely related to processing the gap as an integrated object.
These findings follow an evolutionary logic, as 'emotion induced blindness' may be adaptive in forcing us to register important stimuli, but would quickly become a liability if attention could not be reallocated towards other relevant information necessary for the execution of an appropriate response.
We observed that volunteers were more likely to report ILI symptoms during their first survey than in subsequent surveys, suggesting that ILI might have been a stimulus for registering.
In the work reported here, we addressed the problem of whether the brain has any system for registering sequences of visual stimuli in terms of their temporal regularity and irregularity.
In addition, other cortical areas related to the reward system of the brain were also activated; in one (SOFC; Fig. 6A), the activity is related linearly to the declared intensity of the experience of desire while in another (area MC in Fig. 6B) the relationship is quadratic, implying that it registers whether the stimulus is desirable or undesirable without classifying it further.
