| Research Abstract |
We hypothesized that humans have neural system of automatic change detection to survive. In this network, the change is automatically detected using a memory trace by comparing the abrupt event with the preceding condition. Present study investigated the relationship between neural activities and the length of preceding steady state (PSS). As a result, the amplitude of somatosensory M100 and auditory N1m were dependent on the length of PSS before changes. It got larger when the PSS. Therefore, humans will have neural system of automatic change detection.
