Noise exposure during early development influences the acoustic startle reflex in adult rats

Noise exposure during the critical period of postnatal development in rats results in anomalous processing of acoustic stimuli in the adult auditory system. In the present study, the behavioral consequences of an acute acoustic trauma in the critical period are assessed in adult rats using the acoustic startle reflex (ASR) and prepulse inhibition (PPI) of […]

Restoration of call attractiveness by novel acoustic appendages in grey treefrogs

Ethologists have often reported preferences for novel signals, especially if they are more extravagant than normal signals. Such preferences presumably reflect sensory biases that may promote the evolution of both novel and complex signals. We tested behavioural responses of female grey treefrogs, Hyla versicolor, to novel complex calls in relation to the response properties of […]
