Background: Studying saccades is a useful tool to investigate brain function. There is still controversy regarding deficits in prosaccades in Alzheimer’s disease (AD), and a study of saccades in subjects with mild cognitive impairment (MCI) has not been ...

The Limitations of Reward Effects on Saccade Latencies: An Exploration of Task-Specificity and Strength [PDF]
Saccadic eye movements are simple, visually guided actions. Operant conditioning of specific saccade directions can reduce the latency of eye movements in the conditioned direction. However, it is not clear to what extent this learning transfers from the

Quantitative meta-analysis of fMRI and PET studies reveals consistent activation in fronto-striatal-parietal regions and cerebellum during antisaccades and prosaccades [PDF]
The antisaccade task is a classic task of oculomotor control that requires participants to inhibit a saccade to a target and instead make a voluntary saccade to the mirror opposite location.

Instability of Oculomotor Control in Parkinson's Disease Without Freezing of Gait: Evidence From Reflexive and Voluntary Saccade Variability. [PDF]
This study found that people with Parkinson's disease without freezing of gait show higher error rate and peak velocity to amplitude ratio during prosaccade task compared to controls. Also, Parkinson patients show more variation in gain, peak velocity, peak acceleration and peak velocity to amplitude ratio compared to control group.

Ocular Motor Abnormalities in Functional Neurological Disorder: A Video-Oculography Study. [PDF]
Abstract Background Functional neurological disorders (FND) can include various sensory, motor or cognitive symptoms. Eye movement recordings, measured through video‐oculography, could serve as biomarkers for characterizing these dysfunctions in FND.

Convergence Deficits in Myoclonus-Dystonia Point to Cerebellar Impairment. [PDF]
Abstract Background Myoclonus‐dystonia (M‐D) is a monogenic movement disorder, with proposed cerebellar dysfunction. Vergence eye movement deficits, characteristics of degenerative cerebellar disease, have not been studied in M‐D. Cerebellar transcranial alternating current stimulation (tACS) is considered a potential therapeutic approach.

Conflicting Motor Plans and Sensory Attenuation: Evidence From Event-Related Potentials for Sounds Generated by Pro- and Antisaccades. [PDF]
ABSTRACT The reduction of neural responses to self‐ versus externally generated stimuli has been ascribed to predictions based on an efference copy of motor commands. However, general predictive mechanisms not specific to movements may also play a role.

Affective Modulation of Preparatory Cognitive Activity. [PDF]
ABSTRACT This EEG and eye‐tracking study investigated affective influences on cognitive preparation using a precued pro−/antisaccade task with emotional faces as cues. Negative information interfered with preparatory processes with high but not low executive function load.

Latent State-Trait and Latent Growth Curve Modeling of Smooth Pursuit Eye Movements. [PDF]
ABSTRACT Smooth pursuit eye movement (SPEM) performance has previously been shown to have good reliability. While quantifying the relative amounts of reliable trait and state influences on SPEM is relevant to different lines of research including individual differences, clinical and experimental research, this has not yet been done.

Saccadometry Findings in Migraine Patients Without Aura. [PDF]
This study highlights cognitive control and executive dysfunctions in patients with migraine without aura, measured through antisaccadic eye movements. While prosaccadic movements were largely preserved, significant difficulties were observed in the antisaccade test across all parameters.
