- The neuropeptide CCHamide2 regulates diuresis in the Chagas disease vector Rhodnius prolixus
Summary: The neuropeptide RhoprCCHamide2 has a dual diuretic effect, enhancing the serotonin-induced secretion by Malpighian tubules, and inhibiting serotonin-induced absorption across the anterior midgut in Rhodnius prolixus.
- Responses of compass neurons in the locust brain to visual motion and leg motor activity
Summary: In desert locusts, neurons of the central complex, involved in spatial orientation and navigation, change their activity during visual large-field motion and walking activity.
- Bark beetles use a spring-loaded mechanism to produce variable song patterns
Summary: Destructive bark beetles use a spring-loaded mechanism to produce variable songs.
- Sound localization behavior in Drosophila melanogaster depends on inter-antenna vibration amplitude comparisons
Highlighted Article: Walking Drosophila melanogaster steer toward sounds to their front, but away from sounds to their rear. These behaviors are explained by a simple rule: flies steer away from the antenna with the larger vibration amplitude.
- The brain behind straight-line orientation in dung beetles
Summary: Insights into the neural mechanisms underlying compass orientation in dung beetles are placed into the context of the mechanisms of other insects.
- Monopolatic motion vision in the butterfly Papilio xuthus
Summary: By measuring butterflies' behavioural responses to moving images containing both polarization and intensity contrast, we infer the photoreceptors and early neural circuits involved in motion detection.
- Innate visual preferences and behavioral flexibility in Drosophila
Summary: An operant conditioning paradigm in a multiple-choice maze shows that innate visual preferences can be transiently modulated in Drosophila via optogenetic activation of NPF-expressing neurons.
- Differences in spatial resolution and contrast sensitivity of flight control in the honeybees Apis cerana and Apis mellifera
Summary: Closely related honeybee species exhibit surprising differences in their spatial resolution and contrast sensitivity when controlling flight.
- Invertebrate serotonin receptors: a molecular perspective on classification and pharmacology
Summary: Many 5-HT receptors have been characterized at the molecular level in diverse invertebrate species. This review considers how to classify and name these heterologously expressed receptors and compares their pharmacological properties.
