Sequential multimodal sensory integration drives foraging decisions in leaf-cutting ants: Volatiles, contact cues and phytochemistry

This study identifies the sequential sensory cues used by leaf-cutting ants to select host plants, revealing how olfactory and contact cues influence foraging decisions.

Developmental Olfactory Experience Dissociates Hedonic Valence from Exploratory Arousal in Drosophila melanogaster

This study shows that early-life olfactory experience in Drosophila alters exploratory behavior without changing the hedonic valence of odors.

Subjective rather than absolute reward value determines long-term memory formation in honey bees

This study shows that honey bees evaluate reward value relative to prior experience, influencing long-term memory formation through subjective assessment rather than absolute reward concentration.

Sensory adaptation modulates coding and perceptual quality of odor mixtures

This study investigates how sensory adaptation in honeybees affects odor mixture coding and perceptual quality, showing altered activation patterns and improved detection of non-adapted stimuli.

Plasticity in inhibitory networks improves pattern separation in early olfactory processing

The paper investigates how inhibitory plasticity in the honeybee antennal lobe improves pattern separation during odor learning by suppressing shared compounds and enhancing distinct ones.

Olfactory learning modulates a neural circuit mediating innate odor-guided behavior in Drosophila

This study shows that olfactory learning modulates second-order olfactory neurons in Drosophila, affecting innate odor-guided behavior through bidirectional plasticity.

Gain modulation and odor concentration invariance in early olfactory networks

The paper investigates how early olfactory processing in honey bees maintains odor representation stability across concentrations using GABA-A and GABA-B receptor-mediated inhibition.

Experience-dependent tuning of early olfactory processing in the adult brain

This study shows that reduced olfactory experience in adult honey bees leads to less developed antennal lobes, reduced inter-individual variation in glomerular responses, and impaired odor discrimination in learning assays.
