A research dataset analyzing the 'Compliance Trap' in frontier AI models. It documents how compliance-forcing instructions under adversarial pressure can cause metacognitive collapse, with 8 of 11 tested models affected. The dataset was created by author 'schema-eval-anon' and was last updated on May 1, 2026.
This dataset documents a clinical trial with 20 participants (10 with chronic spinal cord injury, 10 healthy) who received transspinal direct current stimulation (tsDCS). It evaluates changes in transspinal evoked potentials (TEPs) recruitment curves and spinal inhibitory mechanisms across multiple spinal segments before and after stimulation sessions. The study reports significant, muscle-dependent changes in motor output for specific muscles in different subject groups.
Supplementary Table S1 provides genome information for species used in a study on Hoxa9 and Hoxc9 gene functions in sharks. The 9.7 KB XLSX file was authored by Yuumi Yoshioka and last updated on April 21, 2026. Its specific contents are described as genome information for the species involved in the research.
Yukon, Canada. A bedrock geological map for the Mount Freegold district within the Dawson Range. The dataset is published by the Government of Yukon on the open_canada platform and was last updated on 2026-04-17. The specific data format and content are not detailed in the available metadata.
Processed data from a neuroscience study includes neuronal locations, activity traces, regional labels, and tail movement metrics. WEI QIN authored this dataset, which was last updated on April 21, 2026. The data likely contains processed measurements derived from original video recordings.
Underwater video footage and 12-megapixel still images were collected from 79 stations across two legs during the SOL5117 survey in the Joseph Bonaparte Gulf. The survey was conducted by Geoscience Australia in collaboration with AIMS and MAGNT aboard the R.V. Solander between 30 July and 30 September 2010. Data includes towed-video transects and shipboard photographs of barcoded biological specimens from seabed environments like banks, channels, and plains.
Sahen Gupta's study presents a detailed single-case intervention and process report on an elite cricketer experiencing anxiety before an ICC Cricket World Cup. The dataset includes quantitative results showing significant reductions in anxiety (−56.2%) and threat appraisals (−50%), alongside qualitative process reports on cognitive restructuring. It employs a multiple baseline design across 12 therapy sessions over 14 weeks with pre-, mid-, post-, and follow-up measurements.
A theoretical study proposes a geometric framework for redefining electroencephalographic (EEG) frequency bands based on logarithmic scaling. The framework uses the mean adult alpha rhythm as a reference and a constant scaling ratio of 1.7275 to derive band centers and boundaries. The model was authored by Sultan Tarlacı and published on figshare in March 2026.
1973 participants from 30 neuroimaging studies were analyzed to compare brain structure and function in Alzheimer's Disease and Mild Cognitive Impairment patients with and without depression. The coordinate-based meta-analysis identified decreased gray matter volume in the right hippocampus and altered neural activity in frontal and temporal gyri. Author Yang Du synthesized studies from PubMed, Embase, PsycINFO, and Cochrane Library spanning 1995 to 2025.
A multimodal coordinate-based meta-analysis synthesizes findings from 30 neuroimaging studies involving 1,973 participants. It explores structural and functional brain alterations in Alzheimer's Disease and Mild Cognitive Impairment patients with depression. The analysis identifies decreased gray matter volume in the right hippocampus and altered neural activity in frontal and temporal gyri.
346 X-ray sources cataloged from a 942-kilosecond Chandra Observatory exposure of the Chandra Deep Field South between 1999 and 2000. The catalog includes flux limits for soft and hard energy bands and presents optical identifications for approximately 85% of the sources using R-band imaging data. NASA HEASARC created this online catalog in June 2002 based on data from Giacconi et al. (2002).
56.8 KB Excel file contains tabular data from a multi-omics mouse model study investigating semaglutide's effects on diabetic cognitive impairment. The dataset integrates fecal metagenomics, bile acid profiling, cerebral proteomics, and metabolomics from a 12-week treatment. Author Liqin Qi published the data under CC BY 4.0 in March 2026.
A 12-week study in a mouse model of diabetic cognitive impairment (DCI) integrates fecal shotgun metagenomics, targeted bile acid profiling, cerebral proteomics, and metabolomics. The dataset documents the neuroprotective effects of semaglutide (SE) treatment, linking gut microbiota remodeling to modulation of cerebral sphingolipid pathways.
A collection of structured motor imagery EEG datasets for EEG-based MI decoding research. The data, hosted by Jiaheng-Wang on Hugging Face, was last updated on 2026-05-08. Raw EEG signals are band-pass filtered between 0.5 and 48 Hz with a notch filter, and trials are extracted from -1 to 4 seconds relative to cue onset.
30 high myopia patients and 31 healthy controls underwent resting-state fMRI scans to explore spontaneous brain activity abnormalities. Huihui Wang published this research data on figshare in March 2026. The analysis used amplitude of low-frequency fluctuation (ALFF), fractional ALFF (fALFF), and regional homogeneity (ReHo) methods.
Geoscience Australia Data published this legacy product on data_gov_au. The dataset describes cross-bedded tidal mega-ripples, a geological feature, from King Sound in northwestern Australia. The product was last updated on 2026-04-30, but no abstract or detailed metadata is available.
Eight elite female ice hockey players underwent magnetoencephalography (MEG) scans while visualizing a scripted play. The study identified a principal hub of neural activity in the posterior left hemisphere cortex surrounding the intraparietal sulcus. This dataset, authored by Audrey Alice Potts and last updated in March 2026, contains the results of this exploratory analysis.
A 2026 study by Carina Graf compares the performance of commercial 1Tx32Rx and 8Tx32Rx head coils for 7T MRI neuroimaging in six healthy volunteers. The research evaluates seven standard sequences, including B0/B1+ mapping, MP2RAGE, R2*-mapping, MRS, EPI time series, and DTI, on a Siemens MAGNETOM Terra system. Data quality was found to be comparable, with the 8Tx32Rx coil showing specific improvements in inferior brain B1+, spinal cord visibility, brainstem MRS SNR, and white matter tract definition.
Carina Graf's research article compares the 1Tx32Rx and 8Tx32Rx head coils for 7T neuroimaging. The study analyzes data from six healthy volunteers across seven MRI sequences, including B0/B1+ mapping, MP2RAGE, R2*-mapping, MRS, EPI time series, and DTI. It concludes that the 8Tx32Rx coil provides comparable or improved data quality for standard protocols.
A 2026 study by Carina Graf compares the performance of 1Tx32Rx and 8Tx32Rx head coils for 7T MRI neuroimaging in six healthy volunteers. The dataset includes results from seven standard MRI sequences: B0 and B1+ mapping, anatomical T1-weighted MP2RAGE, R2*-mapping, single-voxel spectroscopy (MRS), echo-planar imaging time series, and diffusion tensor imaging (DTI). It finds comparable data quality between coils, with specific advantages for the 8Tx32Rx coil in certain regions and sequences.
