China-based data from 3,983 adults aged 60 and older from the China Health and Retirement Longitudinal Study (CHARLS). The dataset supports research on the association between adverse childhood experiences and motoric cognitive risk syndrome, with mediation analysis for depression and chronic pain. The supplementary material was uploaded by figshare admin karger in April 2026.
Research data from a 2026 study investigating the role of α2,6-sialylation of Integrin β3 in Human cytomegalovirus (HCMV) entry into fibroblasts. The dataset, shared by author Taowen Pan on figshare, includes results from quantitative PCR, flow cytometry, immunofluorescence, and virological assays. It supports findings on how the sialyltransferase ST6Gal1 modifies Integrin β3 to facilitate viral internalization and signaling.
370 distinct X-ray point sources detected in an extremely deep 1-megasecond survey of the Hubble Deep Field North region, performed by the Chandra X-Ray Observatory. The catalog, created by NASA HEASARC in March 2002, lists sources across four energy bands with precise positional accuracy. It reaches flux limits of approximately 3e-17 ergs cm-2 s-1 in the soft band and 2e-16 ergs cm-2 s-1 in the hard band.
A unified collection of multiple brain datasets from the Brain Data Science Platform. It includes de-identified electroencephalography (EEG) and polysomnography (PSG) recordings for research in epilepsy, delirium, coma, and sleep medicine. All data is open access for non-commercial use and includes code to reproduce results from accompanying publications.
Preprocessed EEG data from a study by Trujillo (In Review) for the journal Brain Sciences. The data is formatted for use with the EEGLAB MATLAB toolbox. The dataset was last updated on July 6, 2026.
37 patients (31.36%) developed postoperative cognitive dysfunction (POCD) in this prospective observational study. The dataset contains receiver operating characteristic (ROC) analysis results evaluating serum irisin levels as a predictive biomarker for POCD, authored by Hongxia Zhang and last updated in April 2026. It is a small dataset (5.5 KB) stored in an XLS file format.
A clinical dataset from a prospective observational study investigating serum irisin as a biomarker for postoperative cognitive dysfunction (POCD) in older patients undergoing hip and knee arthroplasty. The dataset, authored by Hongxia Zhang and last updated in April 2026, contains results from Spearman correlation, multifactorial logistic regression, and receiver operating characteristic analyses. It includes data on 118 patients, with POCD occurring in 37 (31.36%) of them.
Oguzhan Gül published supplementary materials for a systematic review on sedentary behavior, frailty, and exercise psychology constructs in older adults in May 2026. The dataset includes a review protocol, search strategies, and a supplementary table. The total size of the materials is 317.5 KB.
Supplementary file 2 contains research data on the anticonvulsant effects of 6-gingerol, an active compound from ginger. The study, authored by Dorota Nieoczym and last updated on 2026-04-23, investigates the compound's effects using multiple seizure models in zebrafish larvae and mice. The dataset is a 16.5 KB DOCX file shared under a CC-BY-4.0 license on figshare.
A 2026 study by Wei Wang investigates white matter structure-function coupling in HIV-associated asymptomatic neurocognitive impairment (ANI). The dataset includes neuroimaging metrics from 47 ANI patients and 48 matched healthy controls, derived from diffusion tensor imaging (DTI) and resting-state functional MRI (rs-fMRI). It proposes a White Matter Dys-coupling Index (WDI) correlated with clinical and cognitive metrics.
Replication data and programs for the paper 'Cognitive Uncertainty' by Enke and Graeber. The dataset is hosted on The Quarterly Journal of Economics Dataverse and was last updated on July 9, 2026. It is intended to reproduce the tables and figures from the original research.
A dataset of 333 adults aged 60 years and older from the Knight Alzheimer’s Disease Research Center's longitudinal, open-access dataset. It includes cerebrospinal fluid biomarkers, glial biomarkers, and clinical features used to develop machine-learning models for classifying cognitive impairment. The data was published by Merve Türkegün Şengül on April 23, 2026.
333 adults aged 60 years and older from the Knight Alzheimer’s Disease Research Center's longitudinal dataset. This dataset was used in a study to evaluate glial and cerebrospinal fluid biomarkers for classifying cognitive impairment, with models achieving AUC up to 0.959. The data was authored by Merve Türkegün Şengül and last updated in April 2026.
9.5 KB Excel file summarizing classification methods and modulation types used to identify place-related neuronal activity in human single-neuron studies. The dataset was authored by Weijia Zhang and last updated on May 26, 2026.
Clinical trial data from a single-center study of 31 children with Self-Limited Epilepsy with Centrotemporal Spikes. The dataset records seizure frequency, sleep architecture from EEG, and subjective sleep quality scores at baseline, 1-month, and 2-month intervals after initiating Perampanel treatment. Biao Jiang authored the dataset, which was published on figshare in April 2026.
Event-related potential (ERP) recordings from 20 humans, 38 dogs, and 11 pigs listening to human, dog, pig, and non-vocal sounds. The dataset includes raw EEG data and analysis files, totaling 4.5 GB, and was published by Boglárka Morvai on figshare in April 2026. It captures neural responses to vocalizations across three phylogenetically distant mammal species.
A mapping study on cognitive production systems conducted in 2019 and 2020 by Javad Ghofrani. The dataset likely contains a list of academic papers and their assigned categories. It is sourced from the paperswithcode platform and is available under an Open Access (green) license.
SERF atomic magnetometer technology was used noninvasively to record event-related magnetic fields in anesthetized rats during audiovisual stimulation. The 8.8 MB dataset, authored by Kexun Tang and last updated in April 2026, captures neural responses across auditory-only, visual-only, and combined audiovisual conditions. Comparisons reveal superadditive enhancement of the M300 component, modulated by sound frequencies and inter-stimulus intervals.
Laura Ferinu published eye tracking data on figshare in April 2026. The dataset likely contains measurements from an experiment comparing audiovisual speech integration in children with developmental language disorder (DLD) and typically developing peers. It includes accuracy scores and eye movement data recorded while children viewed incongruent audiovisual word stimuli.
A 2026 case report from figshare details a patient with Brucella encephalitis and mild cognitive impairment.
