Neurobiology of smooth pursuit eye movement deficits in schizophrenia: an fMRI study.
OBJECTIVE Smooth pursuit eye movements are abnormal in patients with schizophrenia. The investigators used functional magnetic resonance imaging (fMRI) to compare brain hemodynamic response during a smooth pursuit eye movement task in patients with schizophrenia and healthy comparison subjects. METHOD Fourteen patients with schizophrenia and 14 healthy comparison subjects performed a smooth p...
متن کاملSmooth-pursuit eye-movement deficits with chemical lesions in macaque nucleus reticularis tegmenti pontis.
Anatomic and neuronal recordings suggest that the nucleus reticularis tegmenti pontis (NRTP) of macaques may be a major pontine component of a cortico-ponto-cerebellar pathway that subserves the control of smooth-pursuit eye movements. The existence of such a pathway was implicated by the lack of permanent pursuit impairment after bilateral lesions in the dorsolateral pontine nucleus. To provid...
متن کاملSmooth-pursuit eye movement deficits with chemical lesions in the dorsolateral pontine nucleus of the monkey.
1. Anatomical and single-unit recording studies suggest that the dorsolateral pontine nucleus (DLPN) in monkey is a major link in the projection of descending visual motion information to the cerebellum. Such studies coupled with cortical and cerebellar lesion results suggest a major role for this basilar pontine region in the mediation of smooth-pursuit eye movements. 2. To provide more direct...
متن کاملSmooth pursuit eye movement deficits after pontine nuclei lesions in humans.
Eye movements were recorded electroculographically in four patients with basal pontine lesions, demonstrated by MRI. The most prominent eye movement abnormality observed was mild to severe impairment of smooth pursuit and optokinetic nystagmus, mainly ipsilateral to the lesion. This abnormality is thought to result from damage to the pontine nuclei, which form a crucial relay between the cerebr...
متن کاملMeasurement of Pixel Number Variation Abnormality in Pursuit Eye Movement of Children with Autism
In Japan, the prevalence of autism, a condition that affects communication and social development, is 10 times higher than it was in the past. The number of children receiving special education in public elementary and junior high schools across Japan has surpassed 90,000, corresponding to an increase of 7.4-fold over the past 20 years (since 1993). The authors aimed to establish an objective d...
