Damage to brain ‘hubs’ causes extensive impairment

Injuries to six brain areas are much more devastating to patients’ abilities to think and adapt to everyday challenges than damage to other parts of the brain, scientists at Washington University School of Medicine have learned.

Imaging pinpoints brain regions that ‘see the future’

Comparing images of brain activity in response to the “self-remember,” left, and “self-future” event cues, researchers found a surprisingly complete overlap among regions of the brain used.Using brain imaging, researchers from Washington University in St. Louis have identified several brain regions that are involved in the uniquely human ability to envision future events. The study, to be published in the journal PNAS, provides evidence that memory and future thought are highly interrelated and helps explain why future thought may be impossible without memories. Findings suggest that envisioning the future may be a critical prerequisite for many higher-level planning processes.
