Finally, we hypothesize that structural deficits across the corpus callosum may contribute to the abnormal asymmetry of intra-hemispheric connectivity in schizophrenia. ...
Recently, a growing body of data has revealed that beyond a dysfunction of connectivity among different brain areas in schizophrenia patients (SCZ), there is also an abnormal asymmetry of functional connectivity ...
Differences in area and volume of the corpus callosum were greatest in patients whose condition was chronic relative to patients with a first episode, as well as the controls (Collinson et al., 2014) ...

The kinetics of dynorphin signal activation, duration and spread were characterized in striatum using a combination of photorelease, sensor imaging and electrophysiology. ...
Patients with schizophrenia and their unaffected relatives have a specific deficit in sleep spindles, a defining oscillation of Stage 2 non-rapid eye movement sleep that, in coordination with cortical ...

The basal ganglia also target the dopaminergic, cholinergic, and serotonergic centers of the brainstem and basal forebrain, and the reticular nucleus of the thalamus, structures broadly implicated in the ...
In the core mechanism of the model, oscillatory patterns in cortex are selected by and routed through the basal ganglia to the thalamus phase-coherently, then circulated back to widely separated areas ...
Schizophrenia is also typified by abnormalities of the corpus callosum, and of interhemispheric coordination (Foong 2000; Whitford et al. 2010; Hoptman et al. 2012) . ...
