Summary: The study indicates that spiking GABAergic LNs show a uniform rise in intracellular calcium in all innervated glomeruli upon odorant stimulation, while nonspiking LNs exhibit odorant-specific and varied glomerular calcium signals, resulting in distinct, glomerulus-specific tuning curves. The cell type-specific differences in calcium dynamics suggest that spiking LNs primarily play a role in interglomerular signaling, while nonspiking LNs are important for intraglomerular signaling.

Summary: In fruit flies, chronic exposure to odors at normal concentrations in natural environments has a mild effect on olfactory behavior. This is different from the effect of higher concentrations of odors, which reduce the aversion to familiar odors in fruit flies.

Summary: This review provides an overview of the important cell type-specific functional properties of different types of projection neurons and local interneurons in the antennal lobe of the cockroach, highlighting the specialized roles they play in olfactory processing. The experimental system of the cockroach Periplaneta americana has elucidated important biophysical and cellular bases of intrinsic physiological properties of these neurons.

Summary: This article investigates the problem of stimulus recognition in the locust olfactory system. The researchers found that locusts can robustly recognize trained odorants even with various variations in stimuli. The results suggest that a linear statistical decoding scheme can resolve the issue of neural variability and behavioral stability.

Summary: This review recapitulates the establishment and original meaning of plasticity in neuroscience, introduces the basic composition of the insect olfactory system using Drosophila melanogaster as an example, and outlines experience-dependent plasticity effects observed in various insects. The recent advances in the study of experience-dependent plasticity effects in the olfactory system of D. melanogaster are highlighted, along with discussions on common research problems, overcoming methods, and future directions.

Summary: This paper reviews new information on the structure of the insect olfactory pathways, with a focus on the connection patterns of output neurons from the antennal lobe in moths. The study reveals that the antennal lobe transmits information through six separate tracts and identifies how male moths transmit distinct signals from conspecific and heterospecific females through parallel tracts.

Summary: The Southern house mosquito Culex quinquefasciatus uses its olfactory system to locate human hosts for blood meals, transmitting deadly diseases in the process. The organization of glomeruli in the antennal lobe governs the insect's odor identification and discrimination, with specific connections between receptors and glomeruli shaping behaviors. Studies on the 3D structure of the antennal lobe provide insights into mosquito odor coding and signal processing mechanisms.

Summary: Changes in behaviour can lead to rapid adaptive evolution and speciation, as seen in the fruit fly Rhagoletis pomonella. The reversal in sensory processing of key odours associated with host fruit preference between apple and hawthorn flies may drive ongoing ecological divergence and speciation. Specific neural pathway changes in sensory modalities could be a broad mechanism for animal behavior changes, contributing to the creation of new biodiversity.

Summary: Honeybees are used extensively to study olfactory learning and memory processes due to their ability to discriminate and remember odors. Evidence suggests that changes in early olfactory processing contribute to the bees' ability to recognize relevant odors, facilitating discrimination adjusted to their own experience.

Summary: The initial representation of the instantaneous temporal information about food odor concentration in the antennal lobe was examined in this study. ON neurons encode the rapid concentration increase at pulse onset and the pulse duration, while OFF neurons encode the rapid concentration decrease at pulse offset and the duration of the pulse interval.

Summary: The primary olfactory center of the insect brain, the antennal lobe (AL), contains various types of neurons, including projection neurons (PNs), local interneurons (LNs), and centrifugal neurons (CNs), which participate in olfactory information processing through different pathways. Research found that projection neurons usually target specific brain regions, while centrifugal neurons may include several previously unknown types.

Summary: The study reveals that sensory neurons in the larval antennae of the red flour beetle are reused in the adult stage, while the structure of the antennal lobe undergoes transformation. The formation of adult glomeruli in the antennal lobe during mid-metamorphosis is a common feature among different insect species, although the role of Orco in development may vary.

Summary: In this study, the neuronal activity in the honey bee's peripheral olfactory system, the antennal lobes, was imaged. A new approach was used to analyze the causal connections between the glomeruli instead of just focusing on their activity patterns. The analysis showed that these connections are present even without olfactory stimulation and become odorant-specific upon exposure to an odor pulse.

Summary: The honeybee Apis mellifera L. is a key pollinator and scientific model organism, with olfactory perception in mating behaviors of males (drones) and queens, as well as brain pathways involved in processing pheromones, being focal points of research. New evidence suggests the existence of multiple odorant cues in honeybee mating, including not only queen-produced signals but also drone-produced signals, indicating potential evolutionary changes in their olfactory systems. Exciting research avenues are being explored to deepen our understanding of the neural basis of bees' mating behaviors.

Summary: Proper brain development relies on timely availability of thyroid hormone (TH), which requires regulated expression of TH signaling components. Abnormal TH levels and mutations in TH signaling components can have detrimental effects on brain development and neurological functions. The involvement of TH signaling in the development of different neurotransmitter systems has gained attention. This review summarizes the regulation of TH signaling components during brain development and discusses how altered TH signaling compromises the development of specific neuron types.
