Auditory N100 gating in patients with schizophrenia: A systematic meta-analysis
2018, Clinical NeurophysiologyCitation Excerpt :This finding is well in line with the previous observation that N100 amplitude deficits in schizophrenia become a much more likely finding at long ISIs (Rosburg et al., 2008). This dependency has initially been described by Roth et al. (1980), who revealed much larger group differences for the N100 amplitude at an ISI of 6.75 s than at shorter ISIs (2.25 and 0.75 s), when presenting single tone stimuli (see Shelley et al., 1999 for a similar finding in a passive oddball experiment). A more pronounced deficit at long ISIs could be due to two, possibly related aspects: (a) patients might not perceive the S1 stimuli as salient as healthy controls do; (b) the overall capacity for the N100 response recovery might be limited in patients with schizophrenia.

2011, Biochemical PharmacologyCitation Excerpt :In unmedicated schizophrenia patients, the magnitude of both P50 and N100 responses to the initial stimuli (S1) is generally diminished compared to normal subjects [175–182]. Nonetheless, some studies have demonstrated a number of AEP phenotype variants in schizophrenic patients including a reduced N100 amplitude [183–186] or reduced N100 response to the first stimulus (S1) but not S2 [175,187–191], similar N100 response amplitudes for both S1 and subsequent test stimuli (S2; [192]), and increased responses to only S2 [114,193]. To date it remains unclear whether these differences represent methodological discrepancies or reflect certain subpopulations of schizophrenics.
