Here is one to start with:

Effects of soy lecithin phosphatidic acid and phosphatidylserine complex
(PAS) on the endocrine and psychological responses to mental stress.

Neuropattern, Trier, Germany.
Phosphatidylserine, derived from cow brains, has been shown previously to
dampen the ACTH and cortisol response to physical stress. Further research
investigated the influence of soy lecithin phosphatidylserine
supplementation on mood and heart rate when faced with an acute stressor. In
this study, we investigated the effects of soy lecithin phosphatidic acid
and phosphatidylserine complex (PAS) supplementation on pituitary adrenal
reactivity (ACTH, cortisol) and on the psychological response (Spielberger
State Anxiety Inventory stress subscale) to a mental and emotional stressor.
Four groups of 20 subjects were treated for three weeks with daily dosages
of either 400 mg PAS, 600 mg PAS, 800 mg PAS, or placebo before exposure to
the Trier Social Stress Test (TSST). Treatment with 400 mg PAS resulted in a
pronounced blunting of both serum ACTH and cortisol, and salivary cortisol
responses to the TSST, but did not affect heart rate. The effect was not
seen with larger doses of PAS. With regard to the psychological response,
400 mg PAS seemed to exert a specific positive effect on emotional responses
to the TSST. While the placebo group showed the expected increase in
distress after the test, the group treated with 400 mg PAS showed decreased
distress. These data provide initial evidence for a selective stress
dampening effect of PAS on the pituitary-adrenal axis, suggesting the
potential of PAS in the treatment of stress related disorders. PMID:

Jeff, I encourage to do some study in PubMed (
http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?db=PubMed )
by yourself. You will find plenty of studies of the substances I mentioned.
