fMRI hints 'will' and 'grace' are not equally honest
Honest people tell the truth, even when given a chance to lie, as shown in an fMRI brain study of truth telling and prevarication from Harvard behavioral scientists.
Honest people tell the truth, even when given a chance to lie, as shown in an fMRI brain study of truth telling and prevarication from Harvard behavioral scientists.
The group, led by Joshua Greene, an assistant professor of psychology at Harvard, assessed 35 subjects who attempted to predict random coin flip outcomes while undergoing fMRI. Rewarded for accuracy and punished for inaccuracy, the study design also allowed them to cheat. Researchers found honest individuals displayed little to no additional neural activity in control-related brain regions when telling the truth, but liars did. Prevailing theories behind lie detection, “will” and “grace,” hypothesize that honesty results either from an active resistance to temptation or from a lack of response to it. Study findings lean toward the latter, according to researchers (Proc Natl Acad Sci USA 2009).
FDA Approves Fluorescence Imaging System for Detecting Residual Breast Cancer
April 18th 2024The combination of the optical imaging agent Lumisight and the fluorescence imaging device Lumicell Direct Visualization System, collectively known as LumiSystem, reportedly offers 84 percent accuracy with real-time detection of residual breast cancer after lumpectomy procedures.
Study of Ofatumumab for Multiple Sclerosis Shows 'Profoundly Suppressed MRI Lesion Activity'
April 17th 2024The use of continuous ofatumumab in patients within three years of a relapsing multiple sclerosis diagnosis led to substantial reductions in associated lesions on brain MRI scans, according to research recently presented at the American Academy of Neurology (AAN) conference.
Could a Deep Learning Model for Mammography Improve Prediction of DCIS and Invasive Breast Cancer?
April 15th 2024Artificial intelligence (AI) assessment of mammography images may significantly enhance the prediction of invasive breast cancer and ductal carcinoma in situ (DCIS) in women with breast cancer, according to new research presented at the Society for Breast Imaging (SBI) conference.
