A 2021 study linked early olfactory-bulb responses to unpleasant odors with movement-related brain activity and separately measured rapid backward body sway.

A study compared green-odor compounds, mixtures, and leaf alcohol concentrations. The lower concentration was more pleasant and produced a larger auditory P300 reduction.

In a field study of 54 students, rose scent during learning and sleep was associated with fewer vocabulary-test errors. Extra cueing at testing remains uncertain.

Two rose oxide enantiomers produced different nasal electrical responses despite similar perception and scalp-recorded responses in a small human study.

Three experiments tested whether a citrus cleaner scent makes cleaning-related words and plans more accessible and increases crumb-clearing movements.

Brief continuous exposure reduced perceived intensity for four odors, but pleasantness clearly declined only for the floral mixture at its two lower concentration settings.

A study of same-sex friends and strangers linked body-odor similarity to connection, but its 71% classification result was internal validation, not a forecast of future friendship.

Across Geneva, Liverpool, and Singapore, odor familiarity and identification were associated with pleasantness and odor-specific feelings, without establishing causation.

Three experiments explored how odor preferences change after choosing, including memory tests and payment decisions made without knowing the next odor.

A study of women’s emotional tears found lower retaliation ratios in men during a monetary game, alongside receptor responses and changes in brain activity.
