Understanding how cognitive functions arise from computations occurring in the brain
requires the ability to measure and perturb neural activity while the relevant circuits are …

Multisensory interactions are essential to make sense of the environment by transforming
the mosaic of sensory inputs received by the organism into a unified perception. Brain …

The olfactory environment is first represented by glomerular activity patterns in the olfactory
bulb. It remains unclear how these representations intersect with sampling behavior to …

Experiments in cognitive neuroscience build a setup whose set of controlled stimuli and
rules elicits a cognitive process in a participant. This setup requires researchers to decide …

Stimulating arbitrary collections of as few as 300 neurons in the primary olfactory cortex of
mice suffices for associative learning independent of any odor stimulation. Thus …

Leptin, the product of the Ob (Lep) gene, is a peptide hormone that plays a major role in
maintaining the balance between food intake and energy expenditure. In the brain, leptin …

Despite decades of study, it remains a matter of controversy as to whether in rats taste
identification is a rapid process that occurs in about 250–600 ms (one to three licks) or a …

Differing results in olfactory-based decision-making research regarding the amount of time
that rats and mice use to identify odors have led to some disagreements about odor …

Performance on olfactory tests can be influenced by a number of stimulus characteristics
including chemical structure, concentration, perceptual similarity, and previous experience …

Perceptual learning is an enhancement in discriminability of similar stimuli following
experience with those stimuli. Here, we examined the efficacy of adding additional active …
