Background Noise Contributes to Organic Solvent Induced Brain Dysfunction

Figure 4

Abnormal response magnitude. The potential difference between P₂ and N₀ was measured for each exposure group and compared to that of the nonexposed (control) group. (a) After noise exposure there was a reduction in stimulus response magnitude across a wide range of stimulus levels. (b) This was further confirmed with a truncated stimulus response growth rate (slope). (c and d) Similar, but less severe outcomes were observed after fuel-only exposure. (e and f) Combined exposure to fuel and noise resulted in a significant reduction in stimulus response magnitude which was further supported by a truncated slope.
