Brain Research: The brain forgets in order to conserve energy ♦ Discovery could lead to better recovery after stroke ♦ Studies tie the hormone to brain's 'pleasure' center

The brain forgets in order to conserve energy Our brains not only contain learning mechanisms but also forgetting mechanisms that erase "unnecessary" learning. A research has now been able to describe one of these mechanisms at the cellular level.
New role for insulin: Studies tie the hormone to brain's 'pleasure' center Insulin, the hormone essential to all mammals for controlling blood sugar levels and a feeling of being full after eating, plays a much stronger role than previously known in regulating release of dopamine, a neurotransmitter that helps control the brain's reward and pleasure centers
Discovery could lead to better recovery after stroke Researchers have identified a molecule that, after a stroke, signals brain tissue to form new connections to compensate for the damage and initiate repairs to the brain
How Alzheimer's-associated protein tangles spread through brain Investigators have discovered a mechanism behind the spread of neurofibrillary tangles -- one of the two hallmarks of Alzheimer's disease -- through the brains of affected individuals.
