Selective Vulnerability of the Cochlear Basal Turn to Acrylonitrile and Noise
Figure 3
Effects of the different
experimental treatments on compound action potential (CAP) thresholds measured
4 weeks post-exposure for frequencies ranging from 2 to 40 kHz. CAP thresholds
obtained in rats exposed to (a) the 110 dB OBN-4 kHz with or without ACN, (b) to
the 97 dB OBN-8 kHz with or without ACN, or (c) to the 97 dB OBN-16 kHz with or
without ACN (see Table 1 for details). Auditory thresholds measured in control
and ACN alone animals were included in each of the graphs for reference. The
colored areas represent the octave band-noise frequency ranges. Error bars: .
