Predicting and Explaining Human Semantic Search in a Cognitive Model

open access: yes, 2017
Recent work has attempted to characterize the structure of semantic memory and the search algorithms which, together, best approximate human patterns of search revealed in a semantic fluency task.

Egocentric Navigation Abilities Predict Episodic Memory Performance

open access: yesFrontiers in Human Neuroscience, 2020
The medial temporal lobe supports both navigation and declarative memory. On this basis, a theory of phylogenetic continuity has been proposed according to which episodic and semantic memories have evolved from egocentric (e.g., path integration) and ...

Clustering Algorithm Reveals Dopamine‐Motor Mismatch in Cognitively Preserved Parkinson's Disease

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To explore the relationship between dopaminergic denervation and motor impairment in two de novo Parkinson's disease (PD) cohorts. Methods n = 249 PD patients from Parkinson's Progression Markers Initiative (PPMI) and n = 84 from an external clinical cohort.

A physiological marker of recognition memory in adults with autism spectrum disorder? The Pupil Old/New Effect [PDF]

open access: yes, 2020
This study investigated the pupil Old/New effect in individuals with Autism Spectrum Disorder (ASD) and typical development (TD). Participants studied verbal and visual meaningful and meaningless materials in black and white on a computer screen.

Fluid Biomarkers of Disease Burden and Cognitive Dysfunction in Progressive Supranuclear Palsy

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Identifying objective biomarkers for progressive supranuclear palsy (PSP) is crucial to improving diagnosis and establishing clinical trial and treatment endpoints. This study evaluated fluid biomarkers in PSP versus controls and their associations with regional 18F‐PI‐2620 tau‐PET, clinical, and cognitive outcomes.

CSF Monoamine Metabolites and Cognitive Trajectory in Early Parkinson's Disease

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Imaging and postmortem studies indicate that abnormalities in monoaminergic neurotransmission contribute to cognitive impairment in Parkinson's disease (PD). However, it remains uncertain if cerebrospinal fluid (CSF) monoamine metabolites can serve as biomarkers of cognitive decline in early PD.

Semantic Memory and its Relationship to Mental Wandering among Academically Struggling Students

open access: yesمجلة جامعة الأنبار للعلوم الإنسانية
Aims: This research aimed to investigate several key variables among academically struggling students. Specifically, it sought to: (1) assess the level of semantic memory; (2) identify gender-based differences in semantic memory (males vs.

Gait recognition and understanding based on hierarchical temporal memory using 3D gait semantic folding [PDF]

open access: yes, 2020
Gait recognition and understanding systems have shown a wide-ranging application prospect. However, their use of unstructured data from image and video has affected their performance, e.g., they are easily influenced by multi-views, occlusion, clothes ...

Elevated Connectivity During Language Processing Is Associated With Cognitive Performance in SeLECTS

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Self‐Limited Epilepsy with Centrotemporal Spikes (SeLECTS) is associated with language impairments despite seizures originating in the motor cortex, suggesting aberrant cross‐network interactions. Here we tested whether functional connectivity in SeLECTS during language tasks predicts language performance.

Semantic distances of WAIS Similarities word pairs in non-demented adults: An item-level index of semantic memory granularity

open access: yesBrain Research Bulletin
Innovative approaches to test scoring can help neuropsychologists detect subtle semantic memory alterations. We focussed on the Wechsler Adult Intelligence Scale Similarities (SIM) test and calculated an item-level score based on the ‘Leacock & ...
