Age-related response speed deficits arise from specific impairments in sensory evidence accumulation rate
(2021-11)Older adults exposed to enriched environments (EE) maintain relatively higher levels of cognitive function, even in the face of compromised markers of brain health. Response speed (RS) is often used as a simple proxy to ... -
Altered network stability in progressive supranuclear palsy
(2021-07)The clinical syndromes of Progressive Supranuclear Palsy (PSP) may be mediated by abnormal temporal dynamics of brain networks, due to the impact of atrophy, synapse loss and neurotransmitter deficits. We tested the ... -
Associations Between Longitudinal Trajectories of Cognitive and Social Activities and Brain Health in Old Age
(2020-08)Importance Prior neuroimaging studies have found that late-life participation in cognitive (eg, reading) and social (eg, visiting friends and family) leisure activities are associated with magnetic resonance imaging (MRI) ... -
Associations between modifiable risk factors and white matter of the aging brain: insights from diffusion tensor imaging studies
(2019-08)There is increasing interest in factors that may modulate white matter (WM) breakdown and, consequentially, age-related cognitive and behavioral deficits. Recent diffusion tensor imaging studies have examined the relationship ... -
Challenges and future directions for representations of functional brain organization
(2020-10)A key principle of brain organization is the functional integration of brain regions into interconnected networks. Functional MRI scans acquired at rest offer insights into functional integration via patterns of coherent ... -
Cross-species cortical alignment identifies different types of anatomical reorganization in the primate temporal lobe
(2020-03)Evolutionary adaptations of temporo-parietal cortex are considered to be a critical specialization of the human brain. Cortical adaptations, however, can affect different aspects of brain architecture, including local ... -
Delineating between-subject heterogeneity in alpha networks with Spatio-Spectral Eigenmodes
(2021-10)Between subject variability in the spatial and spectral structure of oscillatory networks can be highly informative but poses a considerable analytic challenge. Here, we describe a data-driven modal decomposition of a ... -
Dissecting Transient Burst Events
(2020-10)Increasing efforts are being made to understand the role of intermittent, transient, high-power burst events of neural activity. These events have a temporal, spectral, and spatial domain. Here, we argue that considering ... -
Effect of glucose and sucrose on cognition in healthy humans: a systematic review and meta-analysis of interventional studies
(2021-02)Evidence suggests that plasma glucose levels may influence cognitive performance, but this has not been systematically reviewed and quantified. Objective: The aim of this review was to investigate the potential effects of ... -
EMD: Empirical Mode Decomposition and Hilbert-Huang Spectral Analyses in Python
(2021-03)The Empirical Mode Decomposition (EMD) package contains Python (>=3.5) functions for analysis of non-linear and non-stationary oscillatory time series. EMD implements a family of sifting algorithms, instantaneous frequency ... -
Examining the Neural Correlates of Error Awareness in a Large fMRI Study
(2022-01)Goal-directed behaviour is dependent upon the ability to detect errors and implement appropriate post-error adjustments. Accordingly, several studies have explored the neural activity underlying error-monitoring processes, ... -
Functional biases in attentional templates from associative memory
(2020-12)In everyday life, attentional templates—which facilitate the perception of task-relevant sensory inputs—are often based on associations in long-term memory. We ask whether templates retrieved from memory are necessarily ... -
Generalizing Brain Decoding Across Subjects with Deep Learning
(2022-05)Decoding experimental variables from brain imaging data is gaining popularity, with applications in brain-computer interfaces and the study of neural representations. Decoding is typically subject-specific and does not ... -
Hierarchical modelling of functional brain networks in population and individuals from big fMRI data
(2021-02)A major goal of large-scale brain imaging datasets is to provide resources for investigating heterogeneous populations. Characterisation of functional brain networks for individual subjects from these datasets will have an ... -
Individual variation in brain microstructural-cognition relationships in aging
(2021-02)While all individuals are susceptible to age-related cognitive decline, significant inter- and intra-individual variability exists. However, the sources of this variation remain poorly understood. Here, we examined the ... -
Introducing the tablet-based Oxford Cognitive Screen-Plus (OCS-Plus) as an assessment tool for subtle cognitive impairments
(2021-04)Here, we present the Oxford Cognitive Screen-Plus, a computerised tablet-based screen designed to briefly assess domain-general cognition and provide more fine-grained measures of memory and executive function. The OCS-Plus ... -
A macroscopic link between interhemispheric tract myelination and cortico-cortical interactions during action reprogramming
(2021-12)Myelination has been increasingly implicated in the function and dysfunction of the adult human brain. Although it is known that axon myelination shapes axon physiology in animal models, it is unclear whether a similar ... -
Neuroenhancements in the Military: A Mixed-Method Pilot Study on Attitudes of Staff Officers to Ethics and Rules
(2022-02)Utilising science and technology to maximize human performance is often an essential feature of military activity. This can often be focused on mission success rather than just the welfare of the individuals involved. This ... -
One thing leads to another: anticipating visual object identity based on associative-memory template
(2020-04)Probabilistic associations between stimuli afford memory templates that guide perception through pro-active anticipatory mechanisms. A great deal of work has examined the behavioural consequences and human electrophysiological ... -
Output planning at the input stage in visual working memory
(2021-03)Working memory serves as the buffer between past sensations and future behavior, making it vital to understand not only how we encode and retain sensory information in memory but also how we plan for its upcoming use. We ...
