Tyrosine reverses a cold-induced working memory deficit in humans
CONCLUSION: Tyrosine was effective in protecting against the effects of cold stress on DMTS performance, possibly by preventing cold stress--induced reduction in brain catecholamine levels.
Tyrosine promotes cognitive flexibility: Evidence from proactive vs reactive control during task switching performance.
CONCLUSION: Tyrosine administration enhances brain dopamine & enhances cognitive flexibility.
Alpha-GPC reverses scopolamine-induced amnesia and improves learning in young and old rats.
CONCLUSION: These results show that alpha-GPC improves the performance of animals in both active and passive conditioning tasks. Furthermore, subchronic treatment with the compound enhances in young and restores in aged animals the transduction of the signal, namely, the receptor- mediated production of inositol phosphate and the potassium-induced calcium mobilization. These modifications may represent at least part of the molecular mechanism of action of the compound."
Alpha-GPC may increase the expression of Nerve Growth Factor receptors in the rat cerebellar cortex.
CONCLUSION: These results suggest that choline alfoscerate treatment may increase the expression of NGF receptors in the rat cerebellar cortex."
Alpha--GPC prevents scopolamine--induced learning impairment.
The data suggest that the behavioural effects of alpha-GPC may be related to its property to increase hippocampal ACh synthesis and release."
