Differences in olfactory abilities in men and women SciReports umeauniversity olfactory men women menvswomen
By Bhavana KunkalikarJun 6 2023Reviewed by Lily Ramsey, LLM In a recent study published in the Scientific Reports Journal, researchers compared the responses of men and women to various olfactory stimulations.
The existence of gender-related differences in olfactory ability is still an open field of research with varying and sometimes opposed empirical findings and theoretical explanations. The intensity, valence, and effect on the concentration of n-butanol exposure were evaluated by participants using a Borg CR-100 scale. The category rating scale includes numerical values and verbal descriptors: 0-nothing, 1.5- minimum, 2.5- extremely weak, 6- very weak, 12- weak, 25- moderate, 45- strong, 70- very strong, 90- extremely strong, and 100- near maximal.
The participants' sense of smell and decision-making abilities were determined on the first day. The participants completed a Stroop and three-back task as their first set of functions. On the second analysis day, participants repeated the Stroop and three-back tasks before being fitted with electrodes and placed in the exposure chamber.
No differences were noted between the sexes in assessing perceptual and symptom ratings across the period of extended odor exposure. The study found a significant difference in intensity ratings between sexes, with an estimated difference of -1.35.

Researchers use new deep learning approach to enable analysis of electrocardiograms as languageMount Sinai researchers have developed an innovative artificial intelligence (AI) model for electrocardiogram (ECG) analysis that allows for the interpretation of ECGs as language. This approach can enhance the accuracy and effectiveness of ECG-related diagnoses, especially for cardiac conditions where limited data is available on which to train.
