Study identifies brain network connections associated with anosognosia
A recent study has identified brain network connections that are associated with this condition, providing valuable insights into its underlying mechanisms.
The study you mentioned likely employed neuroimaging techniques, such as functional magnetic resonance imaging (fMRI), to investigate the brain activity & connectivity patterns of individuals with anosognosia.
By comparing these patterns with those of healthy individuals or patients without anosognosia, researchers can identify specific brain networks involved in the condition.
One such network that has been implicated in anosognosia is the default mode network (DMN).
The DMN is a set of brain regions that are active when a person is at rest and not focused on the external environment. It plays a role in self-referential thinking, introspection, and self-awareness.
Studies have shown that individuals with anosognosia often exhibit disrupted connectivity within the DMN.
Additionally, researchers have found altered connectivity between the DMN and other brain networks involved in attention, perception, and cognitive control.
These connections may be important for integrating information about one's own abilities and comparing it with external feedback or reality.
