Tyrosine improves cognitive performance and reduces blood pressure in cadets after one week of a combat training course
Tyrosine negatively affects flexible-like behaviour under cognitively demanding conditions.
Effects on Mood of Acute Phenylalanine/Tyrosine Depletion in Healthy Women
The catecholamine neurotransmitter precursor tyrosine increases anger during exposure to severe psychological stress
TLDR
Tyrosine did not alter most subjective or physiological responses to severe acute stress, but it increased ratings of anger, and the modest increase in anger may be an adaptive emotional response in stressful environments.
Tyrosine Supplementation A Nutraceutical Approach to Counter Heat Stress Induced Cognitive Decline
TLDR
It may be concluded that tyrosine supplementation improves heat stress-induced decrement in attention by maintaining the synthesis and turnover of norepinephrine.
Effect of tyrosine supplementation on clinical and healthy populations under stress or cognitive demands--A review.
Tyrosine Improves Working Memory in a Multitasking Environment
Tyrosine prevents effects of hyperthermia on behavior and increases norepinephrine
Tyrosine supplementation mitigates working memory decrements during cold exposure
A Combination of Nootropic Ingredients (CAF+) Is Not Better than Caffeine in Improving Cognitive Functions
TLDR
It is concluded that in healthy young students, caffeine improves memory performance and sensorimotor speed, whereas CAF+ does not affect the cognitive performance at the dose tested.

Treatment with tyrosine, a neurotransmitter precursor, reduces environmental stress in humans
Tyrosine administration reduces blood pressure and enhances brain norepinephrine release in spontaneously hypertensive rats.
TLDR
Tyrosine injection appears to reduce blood pressure via an action within the central nervous system, since the effect can be blocked by co-administering other large neutral amino acids that reduce tyrosine's uptake into the brain.
Effect of noise on blood pressure and 'stress' hormones.
TLDR
Noise stimulation for 20 min caused a significant increase in diastolic blood pressure and mean arterial pressure and Adrenaline, noradrenaline, prolactin, cortisol and growth hormone concentration in venous plasma were not affected during noise stimulation.

Plasma norepinephrine pharmacokinetics during mental challenge.
TLDR
The results indicate that mental challenge is associated with generally increased sympathetically‐mediated NE release that determines the hemodynamic responses, and measurement of total body and regional NE pharmacokinetics avoids these difficulties.
Hemodynamic and hormonal changes induced by noise.
TLDR
There were no changes in adrenaline and noradrenaline in plasma during maximal noise exposure and the noise induced hemodynamic changes remained 5 minutes after the noise stimulation was stopped but had disappeared after 10 minutes of rest.
