研究の主なアウトカム(著者による)

No change in response latency was observed during exposure. A small, but statistically significant decrease in amplitude was observed with a maximum 1 to 2 min after the start of exposure and turned back to baseline 1 min after exposure. The observed effect might be ascribed to voltage-activated sodium channels.
