Brain Research; Brain mechanism for creating durable memories ♦ 'Inner GPS' study may aid diagnosis of brain diseases ♦ Complete symptom resolution reduces risk of depression recurrence

Brain mechanism for creating durable memories Rehearsing information immediately after being given it may be all you need to make it a permanent memory. Psychologists found that the same area of the brain activated when laying down a memory is also activated when rehearsing that memory.
Reduced activity of a brain protein linked to posttraumatic stress disorder People with post-traumatic stress disorder (PTSD) have reduced activity of the protein serum and glucocorticoid regulated kinase 1 (SGK1) in their prefrontal cortices, and experimentally reducing the protein's activity in rats leads to PTSD-like behavior, according to a new study Augmenting activity of SGK1 may be therapeutic in PTSD.
Complete symptom resolution reduces risk of depression recurrence, People who have had an episode of major depression are at high risk for having another episode.The risk of recurrence is significantly lower for people with complete, rather than partial depressive symptom resolution.
'Inner GPS' study may aid diagnosis of brain diseases A new study sheds light on brain cells in our 'inner GPS,' which may improve understanding of memory loss and wandering behavior in people with Alzheimer's and other neurodegenerative diseases.
