Materials and methods
Participants
Six healthy right-handed volunteers (2 males, mean age 26.94
(3.69) years) took part in the study after giving their written informed
consent. The studywas approved by the local Ethical Committee. Participants
were recruited from the university community and screened for
psychological and medical problems, right-handedness and absence of
contra-indications for exposure to magnetic field. Due to technical failure
data recorded from one participant during the monitoring task
were lost. Hence, for this task data from only 5 subjects were available
for analysis.
