Connectome caricatures remove large-amplitude coactivation patterns in resting-state fMRI to emphasize individual differences

Connectome caricatures remove large-amplitude coactivation patterns in resting-state fMRI to emphasize individual differences - Nature Neuroscience
Dominant coactivation patterns are primarily studied in resting-state fMRI. Here, the authors study the rest of the signal, which reveals ‘caricatured’ connectomes with improved behavioral prediction.

Vulnerability to memory decline in aging revealed by a mega-analysis of structural brain change - Nature Communications
Across 13 longitudinal studies (3,737 adults), the authors show that brain atrophy parallels memory loss, with a stronger coupling in later life. APOE ε4 increases decline, yet genetic risk does not m...

There is no reason why systematic reviews can't be open. The data used for synthesis is *already* open and there are many excellent open source tools that can facilitate the easy sharing of analysis scripts.

Here's a nice guide for performing open systematic reviews doi.org/10.1525/coll...
This paper provides guidance and tools for conducting open and reproducible systematic reviews in psychology. It emphasizes the importance of systematic reviews for evidence-based decision-making and the growing adoption of open science practices. Open science enhances transparency, reproducibility, and minimizes bias in systematic reviews by sharing data, materials, and code. It also fosters collaborations and enables involvement of non-academic stakeholders. The paper is designed for beginners, offering accessible guidance to navigate the many standards and resources that may not obviously align with specific areas of psychology. It covers systematic review conduct standards, pre-registration, registered reports, reporting standards, and open data, materials and code. The paper is concluded with a glimpse of recent innovations like Community Augmented Meta-Analysis and independent reproducibility checks.

The human brain responds to the sounds of both familiar and unfamiliar languages in a similar way, according to research in Nature. The findings might guide future approaches to language learning and rehabilitation. go.nature.com/4ppvsHb #Neuroskyence 🧪

Women seem to retract fewer papers than men — but why?
In an analysis of nearly 900 retracted medical-research studies, the number of female authors is disproportionately low.

Introducing bluffbench, a new tool to evaluate how well LLMs actually see data plots.

When we trick LLMs with secret #RStats transformations, they can miss the visual contradiction.

bluffbench helps us measure this "blind spot" in AI coding agents. Learn more: posit.co/blog/introdu...
When plotting, LLMs see what they expect to see - Posit
Data science agents need to accurately read plots even when the content contradicts their expectations. Our testing shows today's LLMs still struggle here.

Managing Head Exams in Claustrophobic Patients Undergoing #MRI: Challenges and Strategies Using MAGNETOM Free.Max
by Marcelo Fernandes Arêas (Siemens Healthineers, Germany).

🔗 marketing.webassets.siemens-healthineers.com/61813c8f921b...

#RadSky #NeuroSky #DeepResolve #LowFieldMRI #Claustrophobia
This article addresses claustrophobia in #MRI patients and presents strategies to improve the overall patient experience. With its ultra-wide 80 cm bore, the 0.55T MAGNETOM Free.Max scanner is designed to create a less confining environment and enhance comfort. Its compact design and shorter magnet length allow for more flexible patient positioning. Additional measures such as using Contour coils, music during the scan, and cushions for positioning can further increase comfort. The MAGNETOM Free.Max Head/Neck coil has a 12-channel design with 12 integrated pre-amplifiers with three rungs of 4 elements. The coil is tilted to 9 degrees to give patients the feeling of lying on a pillow. The upper part, with 6 elements, can be easily removed. The lower part, also with 6 elements, is usable without the upper part for highly claustrophobic patients. Even with the upper part removed, the AutoAlign option still works. Deep learning-based image reconstruction with Deep Resolve Boost helps denoise the image and achieve good quality. Protocol adjustments, such as selecting prescan normalize, increasing the FOV, and changing the iPAT factor and average, are recommended to increase SNR when scanning without the upper part of the Head/Neck coil.
