Detecting Abnormal Eye Movements in Patients with Neurodegenerative Diseases – Current Insights

Eye and Brain
This review delineates the ocular motor disturbances across a spectrum of neurodegenerative disorders, including Alzheimer’s Disease (AD) and related disorders (ADRD), Parkinson’s Disease (PD), atypical parkinsonism, and others, leveraging advancements ...

Cognitive Dysfunction in Chronic Rhinosinusitis: A Scoping Review

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Cognitive dysfunction is increasingly recognized as an extra‐nasal manifestation of chronic rhinosinusitis (CRS). This scoping review characterizes the primary evidence on cognition in adult CRS, covering measures, treatment response, and incident dementia.

Causal Role of Neural Signals Transmitted From the Frontal Eye Field to the Superior Colliculus in Saccade Generation

Frontiers in Neural Circuits, 2018
The frontal eye field (FEF) and superior colliculus (SC) are major and well-studied components of the oculomotor system. The FEF sends strong projections to the SC directly, and neurons in these brain regions transmit a variety of signals related to ...

Saccadic dysfunction in patients with hypoxic-ischemic encephalopathy [PDF]

Journal of Integrative Neuroscience, 2018
Electrophysiological monitoring of saccadic eye movements in patients with hypoxic-ischemic encephalopathy was carried out. Externally guided saccades (prosaccades) were recorded using a patented hardware-software complex for studying a subject's ...

Reading “Sun” and Looking Up: The Influence of Language on Saccadic Eye Movements in the Vertical Dimension

PLoS ONE, 2013
Traditionally, language processing has been attributed to a separate system in the brain, which supposedly works in an abstract propositional manner. However, there is increasing evidence suggesting that language processing is strongly interrelated with ...

Covert attention beyond the range of eye-movements: Evidence for a dissociation between exogenous and endogenous orienting.

Cortex; a journal devoted to the study of the nervous system and behavior, 2020
The relationship between covert shift of attention and the oculomotor system has been the subject of numerous studies. A widely held view, known as Premotor Theory, is that covert attention depends upon activation of the oculomotor system.

Opsoclonus in Pediatric Patients: Differential Diagnosis and a Practical Approach to Evaluation

Annals of the Child Neurology Society, EarlyView.
ABSTRACT Opsoclonus is an ocular dyskinesia characterized by involuntary, arrhythmic, multidirectional saccades. In pediatrics, opsoclonus is most commonly attributed to the rare neuroinflammatory disorder opsoclonus‐myoclonus‐ataxia syndrome (OMAS), typically considered a paraneoplastic syndrome associated with neural crest tumors. However, opsoclonus

The saccadic and neurological deficits in type 3 Gaucher disease. [PDF]

PLoS ONE, 2011
Our objective was to characterize the saccadic eye movements in patients with type 3 Gaucher disease (chronic neuronopathic) in relationship to neurological and neurophysiological abnormalities.

The basal ganglia and the epilepsies

Epilepsia Open, EarlyView.
Abstract The basal ganglia are an evolutionarily conserved neural circuit best known for the selection and sequencing of voluntary movement. Increasing evidence, however, indicates that these structures also play an important role in regulating pathological brain states, including seizures.

Fixational saccades are more disconjugate in adults than in children. [PDF]

PLoS ONE, 2017
Fixational eye movements are of particular interest for three reasons. They are critical for preventing visual fading and enhancing visual perception; their disconjugacy allows scanning in three dimensions, and their neural correlates span through the ...
