Summary: Honeybees and bumblebees engage in learning flights when discovering a new flower, spending time facing the flower to memorize its surroundings. Larger bumblebees show increased flower facing behavior only when the flower provides a higher sucrose concentration, while smaller bees invest similar effort in facing flowers regardless of concentration. The distribution of effort when learning about flowers parallels the foraging behavior of a colony, with large bumblebees able to carry larger loads and explore further distances compared to smaller ones.

Summary: The study found that the presence of alternative flowers affected bumblebees' ability to discriminate between model and mimic flowers, potentially due to an additional cognitive load imposed by the alternative flowers. Alternative flowers may have beneficial effects on mimic flowers by reducing pollinators' discrimination performance.

Summary: The mesolimbic dopamine system plays a role in attention, appetitive behavior, and reward processing. Dopaminergic signaling in the ventral striatum/nucleus accumbens has been studied for its role in behavioral reinforcement, reward prediction error encoding, and motivational salience. This study reveals that dopamine release in the lateral NAc encodes changes in environmental luminance rather than visual stimulus threat level.

Summary: This study found that honeybee visitation behavior on shared flowers is related to the prevalence of V. ceranae in bumblebees, indicating the importance of flowers in the transmission of V. ceranae.

Summary: Body size does not have a significant impact on foraging behavior and pollen deposition efficiency in plant-pollinator interactions. Only in the case of small flowers of Borago officinalis, small bees deposited more pollen. This suggests that generalist plant-pollinator interactions may be resilient to size mismatches.

Summary: Research shows that foraging bumblebees use a modular landing strategy, unlike honeybees, exhibiting a series of deceleration bouts during landing. This strategy allows bumblebees to effectively forage in challenging conditions and may have potential applications in bio-inspired landing strategies for flying robots.

Summary: This study investigated the impact of body size shifts on plant-pollinator interactions and found that body size did not significantly affect foraging behavior and pollen deposition, suggesting that generalist plant-pollinator interactions may be resilient to size mismatch.

Summary: By recording and observing the activity of neurons in the mouse primary visual cortex, researchers have found that novel images can elicit excessive activity in most neurons, with this novelty response rapidly emerging and having a specific duration. When new image sets are repeatedly presented, the neuronal activity gradually stabilizes. Furthermore, the study reveals that under certain conditions, neural circuits have the capacity to store approximately 15 familiar images.

Summary: In this study, the researchers investigated how sound and movement interact to modulate V1 visual responses in awake, head-fixed mice. They found that sound modulated the activity of a large percentage of light-responsive neurons, with most neurons increasing their activity in the presence of auditory stimuli. The study also revealed that sound and movement had distinct and complementary effects on neuronal visual responses, improving the decoding of visual stimuli from neuronal activity. These findings enhance our understanding of multimodal processing in the awake brain and clarify the potential confounding role of movement in neuronal audiovisual responses.

Summary: Bumblebees perform complex flight maneuvers around the barely visible entrance of their nest upon their first departures, learning visual information about the surroundings and relying on it to return home. They perceive depth information by tracking head orientation, obtaining information in several reference frames when learning about the surroundings of a behaviorally relevant location.

Summary: This study aims to investigate the impact of visual stimuli and their properties on restoration, along with the type of delivery method. Through literature review, a restoration pathway, visual processing framework, and a framework of visual stimuli, visual properties, and restoration were developed.

Summary: Visual processing is influenced by recent stimulus history, and the visual system optimizes encoding by exploiting the temporal statistics of the world. Neurons in the early visual cortex maintain long-term memory traces of individual stimuli, leading to long-term and stimulus-specific adaptation.

Summary: The behavioural state of animals affects neuronal information processing. In insects, locomotion has been shown to change the response properties of visual interneurons, but its effect on photoreceptors is unknown. This study found that the visual processing speed of bumblebees significantly increased when they were walking, and this increase was accompanied by a rise in eye temperature. Artificially heating the head confirmed that the walking-induced temperature increase was responsible for the faster processing speed. Walking also accelerated the visual system to the equivalent of a 14-fold increase in light intensity. These findings suggest that the rise in temperature during walking accelerates the processing of visual information, which is advantageous for processing the increased information flow during locomotion.
