In the short term, acute stress prevents memory storage. According to a 2008 study by University of California Irvine researchers, when cortisol reaches the hippocampus, the brain’s primary structure for consolidating information from short term into long term memory, the structure’s dendritic spines disintegrate rapidly. That’s important, because dendritic spines are the protrusions that branch off of neurons. Learning and memory storage happens effectively when neurons are repeatedly activated across their synapses — a process that effectively tells the brain that a stimulus, behavior or habit is important to retain. When dendritic spines degrade, the brain’s ability to identify and store important information is significantly inhibited.
