Alterations in Spontaneous Brain Oscillations during Stroke Recovery
Amplitude or frequency alterations of spontaneous brain oscillations may reveal pathological phenomena in the brain or predict recovery from brain lesions, but the temporal evolution and the functional significance of these changes is not well known. We performed follow-up recordings of spontaneous brain oscillations with whole-head MEG in 16 patients with first-ever stroke in the middle cerebr...
متن کاملPlasticity of language-related brain function during recovery from stroke.
BACKGROUND AND PURPOSE This study was undertaken to correlate functional recovery from aphasia after acute stroke with the temporal evolution of the anatomic, physiological, and functional changes as measured by MRI. METHODS Blood oxygenation level-dependent contrast and echo-planar MRI were used to map language comprehension in 6 normal adults and in 2 adult patients during recovery from acu...
متن کاملVerbal language spontaneous recovery after ischemic stroke.
OBJECTIVE To analyze the spontaneous recovery of the verbal language on patients who have had an ischemic stroke. METHOD Retrospective analysis of 513 medical records. We characterize referring aspects for data identification, language deficit, spontaneous recovery and speech therapy. RESULTS The average age was 62.2 years old (SD= +/-12.3), the average time of academic experience was 4.5 y...
متن کاملAlterations in Brain Connectivity Underlying Beta Oscillations in Parkinsonism
Cortico-basal ganglia-thalamocortical circuits are severely disrupted by the dopamine depletion of Parkinson's disease (PD), leading to pathologically exaggerated beta oscillations. Abnormal rhythms, found in several circuit nodes are correlated with movement impairments but their neural basis remains unclear. Here, we used dynamic causal modelling (DCM) and the 6-hydroxydopamine-lesioned rat m...
متن کاملmicroRNAs Involved in Regulating Spontaneous Recovery in Embolic Stroke Model
To date, miRNA expression studies on cerebral ischemia in both human and animal models have focused mainly on acute phase of ischemic stroke. In this study, we present the roles played by microRNAs in the spontaneous recovery phases in cerebral ischemia using rodent stroke models. Brain tissues were harvested at different reperfusion time points ranging from 0-168 hrs after middle cerebral arte...
