The Evolutionary Origins of Psychedelics
Humans rely on a bevy of strange natural chemicals to liven up our food and drink, to endure pain, and to change our perspective. We use caffeine from coffee, tea, and yerba mate to stimulate our bodies and minds, capsaicin from red pepper flakes or isothiocyanates in horseradish or wasabi to enliven our food with spice, and codeine or morphine to endure the pain of injuries and surgeries.
Lately, though, some have also turned to psychedelics like psilocybin to change their perspectives. In fact, researchers are beginning to test if they could serve as new treatments for mental health disorders.

William Yule obituary
Psychologist who pioneered the treatment of children after such disasters as the Zeebrugge ferry sinking and the King ’s Cross fireOn 6 March 1987, the Herald of Free Enterprise ferry set sail from the Belgian port of Zeebrugge heading for Dover. The bow doors were not shut and within seconds it flooded with seawater. It capsized and 193 passengers and crew died.Bill (William) Yule, who has died aged 83, was a child psychologist at the Institute of Psychiatry (now the Institute of Psychiatry, Psychology& Neuroscience) in London and head of clinical psychology at what was then the Bethlem Royal and Maudsley hospital. ...

Neuroimaging and behavioral evidence that violent video games exert no negative effect on human empathy for pain and emotional reactivity to violence - Lengersdorff LL, Wagner IC, Mittmann G, Sastre-Yag üe D, Lüttig A, Olsson A, Petrovic P, Lamm C.
Influential accounts claim that violent video games (VVG) decrease players' emotional empathy by desensitizing them to both virtual and real-life violence. However, scientific evidence for this claim is inconclusive and controversially debated. To assess t... (Source: SafetyLit)

Road to RSNA 2023: MRI Preview
The RSNA meeting always showcases the particular benefits MRI brings to the healthcare enterprise, and this year will be no exception. One of the modality's exciting growing edges is cardiac imaging, and attendees can expect to hear a broad range of research on the topic, from how real-time MRI can be combined with deep learning to assess cardiac volumetry and how it can help clinicians "map" the effects of stroke, to using 7-tesla MRI to evaluate ventricular structure and function in patients with high blood pressure and identifying myocarditis after COVID-19 vaccination.
Along with cardiac imaging, other MRI themes at t...

AI detects incidental lung nodules on chest x-rays
In this study, the researchers evaluated imaging results from 14,563 patients who underwent initial chest x-rays in outpatient clinics. Three radiologists categorized nodules into malignancy (group A), active inflammation or infection that needs treatment (group B), (group C), and others (group D). Lesions were considered present when the software’s abnormality score exceeded 15%.According to the findings, the AI software detected unexpected lung nodules in 152 patients (1%). The study authors excluded 72 patients due to inconclusive results because they had no follow-up images. In addition, seven patients were excluded ...

FDG-PET reveals patterns in newly recognized fused in sarcoma proteinopathy
Wednesday, November 29 | 8:20 a.m.-8:30 a.m. | W1-SSNMMI05-3 | E350FDG-PET may help differentiate patients with fused in sarcoma (FUS), a newly recognized proteinopathy causing progressive dementia, from those with Alzheimer’s disease (AD) and frontotemporal dementia (FTD), according to this presentation.Proteinopathy is an umbrella term for distinct neurodegenerative disorders involving the accumulation of specific proteins in brain tissue.In a postmortem study, researchers analyzed FDG-PET imaging data from 28 AD (70.1 ± 9.1 years old), 10 FTD (67 ± 6.7 years old), and three FUS (51.6 ± 17 years old) patients compar...
