Schematic illustration of the prepulse inhibition paradigm. In a block design (7 min), a background wideband noise was continuously delivered as the masker (left leading or right leading), 7 trials contained the startling (pulse) sound alone, and 20 trials contained the prepulse (left leading or right leading) 120 ms or 60 ms preceding the startling (pulse) noise. Trials in each block were presented randomly with the inter-trial interval about 20 s. Note: RNRP (RNLP): right leading masking with prepulse co-location (separation); LNLP (LNRP): left leading masking with prepulse co-location (separation). We have published this paradigm in our privous paper ([24])
