roles for a variety of human cognition functions [48, 68, 70], hereby it is reasonable
to expect different functional roles for hyperlinks as well.
Another important aspect to be explored is the number of participants for reliable
hyperlink estimation. While such a question has been addressed using fMRI and
20 is suggested to be the minimal requirement [43], a systematical investigation
for EEG-based hyperlink is lacking. The number of participants employed in EEGbased studies ranged from 4 to approximately 20. Further studies with a substantially
increased number of participants (preferably to be offline collections) are necessary
to evaluate the suitable number of participants.
10.3 Hyperlink for Social Interaction
Interaction with other human beings, is the essential building element of our
society. Studies on hyperlink for social interaction normally demand simultaneous
recording of multiple brains, with only a few exceptions, in which the researchers
were interested in uni-directional information transfer (e.g. [61]. Consequently, here
different interacting participants are likely to have different roles and their brain
activities cannot be simply considered to comprise similar information (Fig. 10.2).
