Are There Differences in the Brains of Autistic Men and Women?

In both neurotypical males and people on the autism spectrum, researchers found a reduction in resting-state brain function in the default mode network. Additionally, connectivity between the two hemispheres in the visual cortex is reduced in women with ASD. Read More

Researchers Uncover Network Mechanism Underlying Rumination

Researchers have uncovered the neural mechanism underlying rumination. The study reports when rumination occurs, coupling between the core and medial temporal lobe subsystems of the default mode network becomes elevated, while coupling between the core and dorsomedial prefrontal cortex decreases.

Individuals With High Level of Schizotypal Traits Exhibit Altered Brain Structural and Functional Connectivity

People with schizotypal traits exhibited increased structural connectivity probability within the task control network and default mode network. They also had increased variability and decreased stability of functional connectivity within the DMN and between the auditory and subcortical networks. Read More

Brain scans may provide clues to suicide risk

Neuroimaging can be used to assess a person's risk of suicidal behavior. Those with mood disorders, a history of suicidal thoughts, and those with a history of suicide attempts have less connectivity in the cognitive control network. They also have reduced connectivity between the cognitive control network and the default mode network. Read More
