heltok Postad 28 November , 2009 Rapport Postad 28 November , 2009 Effects on memory and learning An array of studies found that caffeine could have nootropic effects, inducing certain changes in memory and learning. Researchers have found that long-term consumption of low dose caffeine slowed hippocampus-dependent learning and impaired long-term memory in mice. Caffeine consumption for 4 weeks also significantly reduced hippocampal neurogenesis compared to controls during the experiment. The conclusion was that long-term consumption of caffeine could inhibit hippocampus-dependent learning and memory partially through inhibition of hippocampal neurogenesis.[91]. In another study, caffeine was added to rat neurons in vitro. The dendritic spines (a part of the brain cell used in forming connections between neurons) taken from the hippocampus (a part of the brain associated with memory) grew by 33% and new spines formed. After an hour or two, however, these cells returned to their original shape.[92] Another study showed that human subjects—after receiving 100 milligrams of caffeine—had increased activity in brain regions located in the frontal lobe, where a part of the working memory network is located, and the anterior cingulate cortex, a part of the brain that controls attention. The caffeinated subjects also performed better on the memory tasks.[93] However, a different study showed that caffeine could impair short-term memory and increase the likelihood of the tip of the tongue phenomenon. The study allowed the researchers to suggest that caffeine could aid short-term memory when the information to be recalled is related to the current train of thought, but also to hypothesize that caffeine hinders short-term memory when the train of thought is unrelated.[94] In essence, caffeine consumption increases mental performance related to focused thought while it may decrease broad-range thinking abilities.

retorik Postad 28 November , 2009 Rapport Postad 28 November , 2009 Energidrycker överlag är väl rätt värdelösa. Du får en kick och du känner att du får massa energi för en stund, sen sänks sockernivån till det lägre än det du hade innan och du känner dig tröttare än vanligt. Ska man dricka någon energidryck ska man dricka nån variant utan socker, just för att inte få sockertopparna. Bra mat och bra träning är det bästa för att hålla energin på topp. Men som en slö pokerspelare, så känner jag igen det här och man letar efter genvägar... Citera
