Changes in expectation impact multiple steps of the visual perceptual decision process in adults [PDF]
Physiological ReportsPerceptual decision‐making processes, particularly in the context of eye movements and reaction times (RT), have been studied to better understand how the brain integrates and responds to sensory information.

Smooth pursuit and memory saccades are impaired in early-stage Parkinson’s disease patients [PDF]
Frontiers in NeurologyIntroductionParkinson’s disease (PD) is a progressive neurodegenerative disease caused by degeneration of dopaminergic neurons in substantia nigra pars compacta (SNc). One of the most prevalent symptoms is eye movement impairment, presenting in 75% of PD

Effects of deep brain stimulation frequency on eye movements and cognitive control [PDF]
npj Parkinson's Disease, 2023 Deep brain stimulation (DBS) of the subthalamic nucleus (STN) is an effective treatment for Parkinson’s disease (PD). Varying the frequency DBS has differential effects on axial and distal limb functions, suggesting differing modulation of relevant ...

Differentiating biomarker features and familial characteristics of B-SNIP psychosis Biotypes [PDF]
Translational PsychiatryIdiopathic psychosis shows considerable biological heterogeneity across cases. The Bipolar-Schizophrenia Network for Intermediate Phenotypes (B-SNIP) used psychosis-relevant biomarkers to identify psychosis Biotypes, which will aid etiological and ...

Increased attentional focus modulates eye movements in a mixed antisaccade task for younger and older adults. [PDF]
PLoS ONE, 2013 We examined performance in the antisaccade task for younger and older adults by comparing latencies and errors in what we defined as high attentional focus (mixed antisaccades and prosaccades in the same block) and low attentional focus (antisaccades and

Eye-movements deficits in schizophrenia: A metanalysis of evidence
European Psychiatry, 2021 Introduction Although eye-movement disorders are one of the most replicated deficits in the psychiatric literature, the strong heterogeneity of results is still an unexplained issue that could be effectively addressed with a quantitative review of ...
