Abstract

Whether stress affects memory depends on which stress pathway becomes
activated and which specific memory system is involved. The activation
of the sympathetic nervous system (SNS), leads to a release of
catecholamines. The activation of the hypothalamic-pituitary-adrenal
(HPA) axis, leads to a release of glucocorticoids. In thus study, it was
investigated whether SNS and/or HPA axis activation are associated with
long-term memory (LTM) and/or working memory (WM) performance in
humans. Thirty-three participants underwent the socially evaluated
cold-pressor test. Salivary alpha-amylase (sAA) was used as a marker for
the activation of the SNS and cortisol as marker for HPA axis
activation. Memory was assessed by means of word lists with 15 words
each. The primacy effect (i.e., the correctly recalled words from the
beginning of the lists) of the serial position curve was considered as
indicator for LTM. The recency effect (i.e., the correctly recalled
words from the end of the lists) were used as estimator for WM
performance. In sAA responders, the recency effect and, therefore, WM
performance increased immediately after the stressor. This was not found
in sAA non-responders. In cortisol responders, the primacy effect and,
thus, LTM performance decreased 20 minutes after the stressor. No change
in LTM performance was found in cortisol non-responders. Our study
supports the assumptions that 1) SNS activation is associated with WM
processes via stimulation of the prefrontal cortex, and 2) HPA axis
activation is associated with LTM processes through interactions with
the hippocampus.
