Make mild moments memorable: add a little arousal

Trends Cogn Sci. 2006 Aug;10(8):345-7. doi: 10.1016/j.tics.2006.06.001. Epub 2006 Jun 21.


In a recent paper Anderson and colleagues reported that emotionally arousing stimuli enhance long-term memory of immediately preceding neutral stimuli. The findings fit well with the perseveration-consolidation hypothesis and with extensive evidence from both human and animal studies indicating that arousal-induced modulation of memory is mediated by beta-noradrenergic activation of the amygdala.
