Brain region-specific profiling of O-GlcNAcylation interactome in Drosophila mushroom body suggests that hypo-O-GlcNAcylation impacts cognitive function by regulating translational activity.

While both implicit and explicit learning augment neurogenesis, adult-born cells differ in their morphology, functional coupling and inhibitory action impacting differentially the olfactory bulb output.

Tetrode recordings show that the amplitude of gamma oscillations encodes for information on contextual odorant identity when observed at the peak phase of the theta oscillation in the olfactory bulb.

Training-induced perceptual gain in the discrimination between odor enantiomers is nostril-specific and structure-based, indicating that early olfactory processing of the chemical features of unirhinal input remains plastic in human adults.

Associative learning, but not passive odorant exposure, induces a novel long lasting functional plasticity in the periphery of mouse olfactory system, making previously encountered odors easier to detect in the future.

Odor conditioning induces two changes in olfactory neurons: non-associative sensory adaptation to odor history, and associative, bidirectional changes in behavioral output that are oppositely regulated in aversive and appetitive learning.

Muscarinic acetylcholine receptor type A in adult Drosophila inhibits Kenyon cells, and is required for aversive olfactory learning and learning-associated synaptic depression between Kenyon cells and their output neurons.

After mating, female mice form a sensory memory of the stud male's pheromones that correlates with striking changes in responsiveness of the specific neural ensemble activated by her partner.

Behavioral assays using Caenorhabditis elegans show that a learned pathogen avoidance following intestinal distention requires specific chemosensory neurons and TRPM channels in the intestine and excretory cell.

A cluster of neurons that integrates inhibitory and excitatory synaptic inputs from the mushroom body output neurons of the appetitive and aversive memory compartments, respectively, triggers upwind steering, mediating memory-driven olfactory navigation behaviors.
