(2009) Eur. J. Neurosci. 29, 1921–1930), but affected significantly the neuronal representation of sound intensity. Although the response thresholds were similar in the exposed and control rats, the neurons in the exposed animals had a longer first-spike latency, a narrower dynamic range, lower maximum response magnitudes and a steeper slope of the rate–intensity functions. The observed anomalies were confined to the mid- and high-frequency regions, whereas no significant changes were found in the low-frequency neurons.
