masking
- Contrast thresholds reveal different visual masking functions in humans and praying mantises
Summary: We investigate alternative explanations for a reported difference between human and insect responses to masked moving gratings, and demonstrate that it is a genuine feature of their visual systems.
- Time-varying auditory gain control in response to double-pulse stimuli in harbour porpoises is not mediated by a stapedial reflex
Summary: Echolocating toothed whales reduce their hearing for short echo delays and unlike bats, do not use a stapedial reflex, but rather forward masking and a central mechanism to evoke the effect.
