... of the ground-dwelling isopod, Porcellionides pruinosus . Isopods were exposed to three different illuminance conditions (<0.01 lx, 1 lx, and 10 lx) over a period of 14 consecutive nights. Behavioral assays included emergence, open-field, habituation to a looming stimulus, and spatial navigation tests...

... habituated foragers with S10%+P or S10%, followed by dishabituation tests with either a 50% sucrose solution paired (S50%+P) or unpaired (S50%) with pollen. Our results indicate that pollen foragers show lower performance than nectar foragers when conditioned with S10%. Interestingly, performance improves...

... plays a key role, as it allows the transfer of past solutions to solve similar new problems. By means of a habituation paradigm, we studied generalization in the invasive crayfish Procambarus clarkii . Once crayfish had habituated their defensive response to a specific water jet, we tested whether...

... in response due to habituation, a non-associative form of learning. In this study, different groups of larvae were reared in water containing different concentrations of glyphosate that are commonly found in the field (50 µg l −1 , 100 µg l −1 , 210 µg l −1 and 2 mg l −1 ). Larvae reared in a glyphosate...

... at the onset of noise exposure ( T sk,start, 17–29°C) was not related to the response. Moreover, we found evidence that torpid bats rapidly habituated to repeated and prolonged noise exposure. † Deceased * Author for correspondence ( [email protected] ) Author contributions J.L., B.M.S...

...Makoto Araki; Takuya Hasegawa; Shohei Komatsuda; Toshiki Nagayama SUMMARY Strong stimuli applied to the tailfan of the crayfish Procambarus clarkii evoked lateral giant interneurone (LG)-mediated tailflips. When the sensory stimulus was applied repeatedly, the response of the LG habituated until...

..., whereas the visual system is functional only from stage 25. At stage 25 and 30, embryos were also exposed to a repeated light stimulus. Stage 30 embryos were capable of habituation, showing a progressive decrease in contractions across stimulations. This process was not due to fatigue as we observed...

...Chloé A. Raderschall; Robert D. Magrath; Jan M. Hemmi SUMMARY Habituation is an active process that allows animals to learn to identify repeated, harmless events, and so could help individuals deal with the trade-off between reducing the risk of predation and minimizing escape costs. Safe...

.... In a captive experiment with food presentation, seals habituated quickly to all sound types presented at normalised received levels of 146 dB re. 1 μPa (r.m.s., root mean square). However, the fast habituation of avoidance behaviour was also accompanied by a weak sensitisation process affecting dive times...

... on a direct collision course at 3 m s -1 while recording from the DCMD axon within the mesothoracic ganglion. Stimulus presentations were designed to test: (i)whether DCMD habituation was related to the frequency of approach, (ii) if habituated DCMDs were able to respond to a novel stimulus and (iii) if non...

... at higher water conductivity. Dipole-elicited strikes exhibit behavioral plasticity. Fish habituate to repetitive dipole stimuli that are not reinforced by prey capture, and they dishabituate after food reinforcement. These experiments characterize paddlefish feeding strikes towards dipole electrodes...

...V. Givois; G. S. Pollack ABSTRACT Auditory receptor neurons exhibit sensory habituation; their responses decline with repeated stimulation. We studied the effects of sensory habituation on the neural encoding of sound localization cues using crickets as a model system. In crickets, Teleogryllus...

... Hz. The higher the rate of stimulus repetition, the more marked were the changes in the A 1 cell responses. In 16 of 17 preparations from two species, habituation had no effect on the adaptation rate in each response, while in seven of eight specimens of another species, the adaptation rate decreased...

.... The system shows habituation and sensitization. The initial gain can be decreased by repetitive sine-wave stimulation of the fCO. Disturbance of the animal (e.g. by tactile stimuli) increases the gain. The gain of the system decreases with increasing stimulus amplitude. The described nonlinearities form...
