Asymptotically Unambitious Artificial General Intelligence

open access: yes, 2020
General intelligence, the ability to solve arbitrary solvable problems, is supposed by many to be artificially constructible. Narrow intelligence, the ability to solve a given particularly difficult problem, has seen impressive recent development ...

A single-system account of the relationship between priming, recognition, and fluency. [PDF]

open access: yes, 2008
A single-system computational model of priming and recognition was applied to studies that have looked at the relationship between priming, recognition, and fluency in continuous identification paradigms.

Correlation of Clinical and Imaging Findings in Early‐Onset Alzheimer's Patients with Distinct Initial Symptoms

open access: yesAlzheimer's &Dementia, Volume 20, Issue S2, December 2024.
Abstract Background Early‐onset Alzheimer’s disease (EOAD), distinct from late‐onset cases, tends to present with atypical cognitive decline, such as, progressive aphasia, apraxia, visuospatial and comportmental impairments,. This study aims to investigate correlations between clinical presentation and PET imaging findings in EOAD patients.

On the Instability of Saturn's Hypothetical Retrograde Co-orbitals [PDF]

open access: yes, 2019
We find an interesting fact that fictitious retrograde co-orbitals of Saturn, or small bodies inside the retrograde 1:1 resonance with Saturn, are highly unstable in our numerical simulations. It is shown that in the presence of Jupiter, the retrograde co-orbitals will get ejected from Saturn's co-orbital space within a timescale of 10 Myr.

Investigating the Association of Concussion and Contact Sport Exposure History With Brain Microstructure Using Quantitative Susceptibility Mapping

open access: yesHuman Brain Mapping, Volume 46, Issue 5, 01 April 2025.
Lower quantitative susceptibility in white matter is associated with a greater number of prior concussions, worse symptoms, and worse neurocognitive function in healthy male and female collegiate‐aged athletes. Results suggest that subtle differences in brain microstructure due to repeated concussions might partially underlie symptom complaints and ...

Beliefs about brain injury in Britain [PDF]

open access: yes, 2010
Primary objective: Surveys have revealed that a high proportion of the public in the US and Canada hold misconceptions pertaining to the sequelae of brain injury.

Transient Global Amnesia with Reversible White Matter Lesions: A Variant of Posterior Reversible Encephalopathy Syndrome?

open access: yesCase Reports in Neurological Medicine, 2015
Transient global amnesia (TGA) is a self-limited disease characterized by isolated amnesia, which resolves within 24 h. In contrast, posterior reversible encephalopathy syndrome (PRES) is a potentially life-threatening disease that usually presents with ...

Memory consolidation from seconds to weeks: A three-stage neural network model with autonomous reinstatement dynamics

open access: yesFrontiers in Computational Neuroscience, 2014
Declarative long-term memories are not created at an instant. Gradual stabilization and temporally shifting dependence of acquired declarative memories on different brain regions - called systems consolidation - can be tracked in time by lesion ...

Dynamic portrait of the retrograde 1:1 mean motion resonance [PDF]

open access: yes, 2018
Asteroids in mean motion resonances with giant planets are common in the solar system, but it was not until recently that several asteroids in retrograde mean motion resonances with Jupiter and Saturn were discovered. A retrograde co-orbital asteroid of Jupiter, 2015 BZ509 is confirmed to be in a long-term stable retrograde 1:1 mean motion resonance ...

Animal Models of Traumatic Brain Injury and Their Relevance in Clinical Settings

open access: yesCNS Neuroscience &Therapeutics, Volume 31, Issue 4, April 2025.
Traumatic brain injury (TBI) is a significant global health concern. Animal models are crucial for understanding the complex pathophysiology of TBI and developing effective treatments. This review explores common animal models of TBI, assessing their strengths and limitations in mimicking human injury.
