| Seeing how odor is processed in the brain Posted: 27 May 2022 06:41 PM PDT A specially created odor delivery device, along with machine learning-based analysis of scalp-recorded electroencephalogram, has enabled researchers to see when and where odors are processed in the brain. The study found that odor information in the brain is unrelated to perception during the early stages of being processed, but when perception later occurred, unpleasant odors were processed more quickly than pleasant odors. Problems with odor perception can be an early symptom of neurodegenerative diseases, so uncovering more of the neural bases of odor perception could help towards better understanding of those diseases in future. |
| New insights into antibiotic resistance Posted: 25 May 2022 07:30 AM PDT Treatment of severe infections caused by pathogenic bacteria relies on 'last resort' antibiotics, but rising resistance by 'superbugs' to most clinically approved drugs leaves patients exposed to possible fatalities. Researchers are focusing on how bacterial cells adapt and resist antimicrobial medications -- with a new article focusing on a hospital strain of Acinetobacter baumannii and its cellular response to important antibiotic colistin. |
