ALTERATIONS IN BRAIN STRUCTURE AND FUNCTION IN CHILDREN WITH FETAL ALCOHOL SPECTRUM DISORDER
(2015-04-23)Fetal Alcohol Spectrum Disorder (FASD) can occur when a mother drinks alcohol during pregnancy. The full spectrum of adverse effects on the brain induced by prenatal alcohol exposure ranges from mild to severe brain ... -
Cardiovascular correlates of arousal and their relationship to saccadic behavior
(2014-11-11)Understanding the effect of subject arousal on saccadic behavior can shed light on the mechanisms by which arousal influences executive and oculomotor systems. Increased vagal activity is a key component of the parasympathetic ... -
Changes in frontal lobe electroencephalographic (EEG) activity recorded during the performance of a spatial working memory task in children with Fetal Alcohol Spectrum Disorder (FASD)
(2013-08-15)Background: Prenatal alcohol exposure causes behavioural, growth and central nervous system deficits in the offspring, termed Fetal Alcohol Spectrum Disorder (FASD). Our lab has previously shown that structured saccadic ... -
Investigating cognitive impairments in amyotrophic lateral sclerosis (ALS) using eye movements and functional magnetic resonance imaging (fMRI)
(2011-09-26)Patients with Amyotrophic lateral sclerosis (ALS) often experience cognitive impairment that accompanies degeneration of the motor system. A valuable tool for assessing cognitive control over behaviour is the antisaccade ... -
Investigating the contribution of the basal ganglia in the selective gating of saccade initiation
(2008-07-22)An important function of the brain is to inhibit irrelevant behaviors. This thesis examines the role of the basal ganglia in response suppression using saccadic eye movements as a model of behavior. We measured the activity ... -
ROLE OF THE FRONTAL EYE FIELD, SUPERIOR COLLICULUS, AND BASAL GANGLIA IN FLEXIBLE SACCADE BEHAVIOR
A distributed network of cortical and subcortical brain regions mediates the control of voluntary behavior, but it is unclear how this complex system may flexibly shift between different behavioral events. This thesis ... -
A study of predicitive capacity and working memory in mild Alzheimer's disease and normal controls using saccadic eye movements
(2013-05-22)Alzheimer’s disease (AD) is a neurodegenerative disorder with no existing cure. Since cognitive control influences saccade behaviour, saccades provide a valuable tool when studying cognitive changes in healthy and pathological ...
