Altered resting-state functional connectivity in cortical networks in psychopathy.
Psychopathy is a personality disorder characterized by callous antisocial behavior and criminal recidivism. Here we examine whether psychopathy is associated with alterations in functional connectivity in three large-scale cortical networks. Using fMRI in 142 adult male prison inmates, we computed resting-state functional connectivity using seeds from the default mode network, frontoparietal ne...
متن کاملAltered Resting State Effective Connectivity of Anterior Insula in Depression
Depression has been associated with changes in both functional and effective connectivity of large scale brain networks, including the default mode network, executive network, and salience network. However, studies of effective connectivity by means of spectral dynamic causal modeling (spDCM) are still rare and the interaction between the different resting state networks has not been investigat...
متن کاملResting state functional connectivity in early blind humans
Task-based neuroimaging studies in early blind humans (EB) have demonstrated heightened visual cortex responses to non-visual paradigms. Several prior functional connectivity studies in EB have shown altered connections consistent with these task-based results. But these studies generally did not consider behavioral adaptations to lifelong blindness typically observed in EB. Enhanced cognitive ...
متن کاملAltered resting state functional connectivity in a subthalamic nucleus - motor cortex - cerebellar network in Parkinson’s Disease
Introduction Parkinson’s disease (PD) is characterized by a loss of dopaminergic projections from the substantia nigra to the basal ganglia, resulting in altered metabolic and electrophysiological functional connectivity (FC) of large scale motor, cognitive and limbic networks [1,2]. Using PET, increased metabolic activity is typically found in the basal ganglia, primary motor cortex and cerebe...
متن کاملAltered functional connectivity in default mode network in absence epilepsy: a resting-state fMRI study.
Dysfunctional default mode network (DMN) has been observed in various mental disorders, including epilepsy (see review Broyd et al. [2009]: Neurosci Biobehav Rev 33:279–296). Because interictal epileptic discharges may affect DMN, resting-state fMRI was used in this study to determine DMN functional connectivity in 14 healthy controls and 12 absence epilepsy patients. To avoid interictal epilep...
