steady state erp
Oct. 7th, 2010 07:12 pmIt is sometimes possible to make overlap into a virtue. Specifically,
if a series of identical stimuli are presented at a fast, regular
rate (e.g., eight stimuli per second), the system will stop producing
complex transient responses and enter into a steady state, in which
the system resonates at the stimulus rate (and multiples thereof).
Typically, steady state responses will look like two summed sine
waves, one at the stimulation frequency and one at twice the stimulation
frequency.
клеви тема. может, писал уже.
при постоянной(и довольно высокой) частоте показывания стимула на ээг появляется волна точно такой же частоты. и тогда можно вывести из ээг, обработан стимул с данной частотой или нет.
