Widrigkeiten im frühen Leben können die globale Gehirndynamik grundlegend verändern. Untersuchungen deuten darauf hin, dass diese unerwünschten Ereignisse die Funktionsweise des Gehirns im gesamten Netzwerk und nicht nur in isolierten Bereichen grundlegend verändern können.

>Traumatic experiences during infancy and childhood can leave a lasting imprint on an individual’s health. New research indicates that these adverse events may fundamentally reorganize how the brain functions across its entire network, rather than just in isolated areas. A [study](https://www.pnas.org/doi/10.1073/pnas.2506140122) published in the Proceedings of the National Academy of Sciences reveals that early life adversity predisposes the adult brain to a state of heightened activity and alters how it responds to threats later in life.

>The persistent impact of childhood hardship on adult mental health is a well-established concept in psychology and neuroscience. Researchers have previously identified links between neglect or abuse and conditions such as anxiety, depression, and addiction. However, the specific biological mechanisms that drive these vulnerabilities remain difficult to pinpoint.

>Past investigations often focused on individual brain regions. This approach left a gap in understanding how different areas of the brain coordinate with one another after trauma. To address this, a team of researchers sought to map brain-wide activity in adults who experienced adversity as infants.
