Reduced natural oscillatory frequency of frontal thalamocortical circuits in schizophrenia.
CONTEXT Converging evidence from electrophysiological studies suggests that in individuals with schizophrenia, electroencephalographic frontal fast oscillations are reduced. It is still unclear whether this reduction reflects an intrinsic deficit of underlying cortical/thalamocortical circuits and whether this deficit is specific for frontal regions. Recent electrophysiological studies in healt...
متن کاملLow-frequency BOLD fluctuations demonstrate altered thalamocortical connectivity in schizophrenia.
The thalamus plays a central and dynamic role in information transmission and processing in the brain. Multiple studies reveal increasing association between schizophrenia and dysfunction of the thalamus, in particular the medial dorsal nucleus (MDN), and its projection targets. The medial dorsal thalamic connections to the prefrontal cortex are of particular interest, and explicit in vivo evid...
متن کاملHigh-frequency somatosensory thalamocortical oscillations and psychopathology in schizophrenia.
Human cortical somatosensory evoked potentials (SEPs), which are presumably generated in afferent thalamocortical and early cortical fibers, reveal a burst of superimposed early (N20) high-frequency oscillations (HFOs), around 600 Hz. There is increasing evidence of an imbalance of thalamocortical systems in schizophrenic patients. In order to assess correlations between somatosensory evoked os...
متن کاملTime-frequency representations-based detector of chaos in oscillatory circuits
Detection of chaotic states in the nonlinear chaotic Chua’s oscillatory circuit has been considered. A new approach, based on the concentration measure of the time-frequency (TF) representation, is proposed for determination of the current circuit state. Parameters of the proposed algorithm are studied in details. The algorithm is applied in the case of moderate noisy signal, as well as for bre...
متن کاملThalamocortical dysconnectivity in schizophrenia.
OBJECTIVE The thalamus and cerebral cortex are connected via topographically organized, reciprocal connections. Previous studies have revealed thalamic abnormalities in schizophrenia; however, it is not known whether thalamocortical networks are differentially affected in the disorder. To explore this possibility, the authors examined functional connectivity in intrinsic low-frequency blood-oxy...
