Brain and Behavior, Volume 15, Issue 4, April 2025.Our findings suggest the vestibulo‐ocular reflex function may be associated with visuospatial perception and learning in Parkinson's disease. Abstract Background Visuospatial impairment is one of the most frequent cognitive deficits in patients with Parkinson's disease (PD).

The Pattern and Stages of Atrophy in Spinocerebellar Ataxia Type 2: Volumetrics from ENIGMA‐Ataxia
Movement Disorders, Volume 40, Issue 4, Page 651-661, April 2025.Abstract Background Spinocerebellar ataxia type 2 (SCA2) is a rare, inherited neurodegenerative disease characterized by progressive deterioration in both motor coordination and cognitive function. Atrophy of the cerebellum, brainstem, and spinal cord are core features of SCA2; however, the evolution and pattern of whole‐brain atrophy in SCA2 remain ...

It's all about the transient: Intra-saccadic onset stimuli do not capture attention [PDF]
, 2012 An abrupt onset stimulus was presented while the participants' eyes were in motion. Because of saccadic suppression, participants did not perceive the visual transient that normally accompanies the sudden appearance of a stimulus.

The temporal evolution of the central fixation bias in scene viewing [PDF]
arXiv, 2016 When watching the image of a natural scene on a computer screen, observers initially move their eyes towards the center of the image --- a reliable experimental finding termed central fixation bias. This systematic tendency in eye guidance likely masks attentional selection driven by image properties and top-down cognitive processes.

How saccadic vision might help with theinterpretability of deep networks [PDF]
arXiv, 2021 We describe how some problems (interpretability,lack of object-orientedness) of modern deep networks potentiallycould be solved by adapting a biologically plausible saccadicmechanism of perception. A sketch of such a saccadic visionmodel is proposed. Proof of concept experimental results areprovided to support the proposed approach.

A second RUBCN variant associated with epileptic encephalopathy and neurodevelopmental delay
American Journal of Medical Genetics Part A, Volume 197, Issue 3, March 2025.ABSTRACT The RUBCN gene encodes a widely expressed protein called Rubicon, the main function of which is to negatively regulate macroautophagy. A single homozygous pathogenic variant of the RUBCN gene has been reported to date in two unrelated consanguineous Saudi families with spinocerebellar ataxia autosomal recessive 15 (OMIM#613516).

Searching and fixating: scale-invariance vs. characteristic timescales in attentional processes [PDF]
, 2011 In an experiment involving semantic search, the visual movements of sample populations subjected to visual and aural input were tracked in a taskless paradigm. The probability distributions of saccades and fixations were obtained and analyzed. Scale-invariance was observed in the saccadic distributions, while the fixation distributions revealed the ...

Relationships between hypometabolism and both β‐amyloid and tau PET in corticobasal syndrome
Alzheimer's &Dementia, Volume 21, Issue 3, March 2025.Abstract INTRODUCTION Alzheimer's disease (AD) pathology causes corticobasal syndrome (CBS) in 21%–50% of patients. Studies have assessed hypometabolism in CBS according to β‐amyloid (A) positron emission tomography (PET), but the understanding of the association of both AD‐tau (T) and A with hypometabolism is incomplete.

Match-action: the role of motion and audio in creating global change blindness in film [PDF]
, 2016 An everyday example of change blindness is our difficulty to detect cuts in an edited moving-image. Edit Blindness (Smith & Henderson, 2008) is created by adhering to the continuity editing conventions of Hollywood, e.g.

Searchers adjust their eye movement dynamics to the target characteristics in natural scenes [PDF]
arXiv, 2018 When searching a target in a natural scene, both the target's visual properties and similarity to the background influence whether (and how fast) humans are able to find it. However, thus far it has been unclear whether searchers adjust the dynamics of their eye movements (e.g., fixation durations, saccade amplitudes) to the target they search for.
