Stimulation of one nostril sometimes sped responses to visual targets on the same side. Seven experiments explored the timing of this cross-sensory shift.

Mice lacking dorsal olfactory sensory neurons struggled to distinguish mirror-image molecules at concentrations where they could detect an odor, offering clues to the role of sensitive receptor inputs.

High sensitivity to isovaleric acid was associated with a functional OR11H7P variant. Cell responses and shared sensitivity across four odors offer clues to individual differences in smell.

A study of 225 people in nine societies found shared odor rankings alongside large individual differences. What do culture and molecular properties explain?

Eucalyptol made ammonia less noticeable, but the mixture felt stronger overall and divided participants on pleasantness.

A 20-person fMRI study found different resting connectivity patterns after pleasant and unpleasant odors, alongside distinct mood findings.

A study using indole found widespread inhibition of mouse odorant receptors, offering clues to how complex mixtures are encoded.

A brief switch from tea to lemon odor delayed responses compared with odorless air. A study explores familiarity, odor grouping, and alternative explanations.

Chocolate-associated odors elicited different inhalation, reaction-time, and skin responses, without a clear gain in explicit discrimination.

Presenting 32 fragrance materials for two minutes each revealed different declines in perceived intensity. The study examined irritation and molecular properties together.
