Executive Function and Fronto-Striatal Circuitry: Insights From Antisaccades, Task Switching, and Parkinson’s Disease
(2010-09-09)Many studies of ‘executive control’ have focused on the prefrontal cortex (PFC), which contains the neuronal functional properties, modulatory neurotransmitters, and network connections with sensory and motor regions to ... -
Microsaccades in Parkinson's disease
(2014-01-10)Individuals with Parkinson’s disease (PD) display deficits in voluntary saccade generation but improved automatic, visually-triggered saccade performance. This can be tested using prosaccades, saccades to visual stimuli, ... -
Predicted Position Error Triggers Catch-Up Saccades During Sustained Smooth Pursuit
Humans are largely visual animals and require that images of objects of interest must be held steadily on the fovea, a region on the retina that allows for high visual acuity. In order to maintain gaze on objects in the ... -
Saccadic eye movements and executive function in children with Fetal Alcohol Spectrum Disorders (FASD): Results from a multi-centered study
(2008-09-04)A serious consequence of maternal consumption of alcohol during pregnancy is the fetal alcohol syndrome (FAS): characterized by growth deficiency (both pre- and post-natal), craniofacial dysmorphology and central nervous ... -
Spatially and Temporally Predictive Saccades and Their Neural Correlates
(2015-10-03)Prediction is needed to compensate for neural delays between a sensory input and an appropriate motor output. We designed an eye movement task to clarify the behavioural control and neural correlates that are involved ... -
Using Eye Movements to Establish a Normative Database of Control Participants Across the Lifespan
As the brain develops and ages, cognitive abilities (e.g., attention and memory) undergo significant functional fluctuations. In order to differentiate neuropathology from natural changes that occur due to development and ...
