Anti-saccades predict cognitive functions in older adults and patients with Parkinson's disease.

open access: yesPLoS ONE, 2018
A major component of cognitive control is the ability to act flexibly in the environment by either behaving automatically or inhibiting an automatic behaviour.

Differences in saccade dynamics between spinocerebellar ataxia 2 and late-onset cerebellar ataxias.

open access: yesBrain : a journal of neurology, 2011
The cerebellum is implicated in maintaining the saccadic subsystem efficient for vision by minimizing movement inaccuracy and by learning from endpoint errors.

Saccadic suppression during voluntary versus reactive saccades

open access: yesJournal of Vision, 2017
Saccades are fast eye movements that reorient gaze. They can be performed voluntarily-for example, when viewing a scene-but they can also be triggered in reaction to suddenly appearing targets. The generation of these voluntary and reactive saccades have been shown to involve partially different cortical pathways.

Microsaccades Tracking by Secondary Speckle Pattern Analysis

open access: yesJournal of Biophotonics, EarlyView.
A new approach for detecting microsaccades is introduced using secondary speckle patterns reflected from the sclera. This method offers potential benefits in capturing subtle eye movements and overcoming limitations in traditional pupil‐tracking systems.

TMS Perturbs Saccade Trajectories and Unmasks an Internal Feedback Controller for Saccades

open access: yesJournal of Neuroscience, 2011
When we applied a single pulse of transcranial magnetic stimulation (TMS) to any part of the human head during a saccadic eye movement, the ongoing eye velocity was reduced as early as 45 ms after the TMS, and lasted ∼32 ms.

The spatial pattern of peri-saccadic compression for small saccades

open access: yesJournal of Vision, 2010
In the temporal vicinity of a saccade onset, visual stability is transiently disrupted and briefly flashed visual stimuli undergo a systematic perceptual mislocalization. Specifically, when a stimulus is flashed around saccade onset, localization judgments are grossly biased toward the saccade endpoint.

Downconversion Master Slave OCT With a Bidirectional Sweeping Laser

open access: yesJournal of Biophotonics, EarlyView.
ABSTRACT This paper explores the challenges of signal processing when using optical coherence tomography (OCT) imaging instruments driven by asymmetric MHz bidirectional sweeping lasers. A downconversion master–slave (DMS) method is proposed as a viable alternative to the traditional OCT protocol.

Rural Counseling Competencies: A Delphi Study

open access: yesJournal of Counseling &Development, EarlyView.
ABSTRACT This study utilized expert consensus to develop counseling competencies for rural practicing counselors, acknowledging the unique challenges of rural counseling. Employing the Delphi method, the study engaged 15 expert panelists across three rounds to identify and refine essential knowledge, skills, and attitudes and beliefs necessary for ...
