Schizophrenia: Altered Brain Structural Connectivity and Association With Neurological Soft Signs

A new study found altered cortical and subcortical networks in those with schizophrenia and their unaffected first-degree relatives. Findings suggest brain regions associated with a genetic predisposition to schizophrenia are partly separated from brain regions implicating neural abnormalities.

The Brain Uses Bodily Signals to Regulate Fear

Study reveals how the brain relies on feedback from the body to regulate fear response. When a mouse's body freezes in response to fear, its heart rate slows, and this leads to attenuated insular cortex activity.

Anxiety Cues Found in the Brain Despite Safe Environment

Virtual reality is helping researchers uncover some of the secrets of anxiety. Using VR, study participants were able to distinguish between safe and dangerous environments in a game. However, brain scans of those with anxiety showed increased activity in the insula and dorsomedial prefrontal cortex while in a safe zone, indicating their brains were associating the safe environment with threat or danger.

Brain anatomy changes with maturation to adolescence

White matter tracts show increasing maturation with age from the back to the front of the brain. The maturations begin as a child reaches 9-12 years of age. The maturity correlates with a critical and formative period of development.
