Tyrosine Reverses A Cold-induced Working Memory Deficit In Humans
Notes for this study:
|Number of Subjects
Tyrosine at 150mg/kg was able to preserve working memory (via matching accuracy tests) during acute cold stress without inherently improving memory during a nonstressful period; the degree or preservation was absolute, and the temperature of control and cold stress was 22°C and 4°C, respectively.
This study failed to find an effect on plasma noradrenaline levels (despite tyrosine being increased), which increased during cold stress.
