"The Cognition-Enhancing Effects of Psychostimulants Involve Direct Action in the Prefrontal Cortex". Biol. Psychiatry. 77 (11): 940–950. doi:10.1016/j.biopsych.2014.09.013. PMC 4377121 . PMID 25499957. The procognitive actions of psychostimulants are only associated with low doses. Surprisingly, despite nearly 80 years of clinical use, the neurobiology of the procognitive actions of psychostimulants has only recently been systematically investigated. Findings from this research unambiguously demonstrate that the cognition-enhancing effects of psychostimulants involve the preferential elevation of catecholamines in the PFC and the subsequent activation of norepinephrine α2 and dopamine D1 receptors. ... This differential modulation of PFC-dependent processes across dose appears to be associated with the differential involvement of noradrenergic α2 versus α1 receptors. Collectively, this evidence indicates that at low, clinically relevant doses, psychostimulants are devoid of the behavioral and neurochemical actions that define this class of drugs and instead act largely as cognitive enhancers (improving PFC-dependent function). This information has potentially important clinical implications as well as relevance for public health policy regarding the widespread clinical use of psychostimulants and for the development of novel pharmacologic treatments for attention-deficit/hyperactivity disorder and other conditions associated with PFC dysregulation. ... In particular, in both animals and humans, lower doses maximally improve performance in tests of working memory and response inhibition, whereas maximal suppression of overt behavior and facilitation of attentional processes occurs at higher doses.

Here’s what matters to millennials. # [1] 20 I have taken both prescribed Adderall and Vyvanse. I prefer Vyvanse as it’s more smooth and I experienced less of a “sweaty-palm” effect while taking it. However, finishing up my Master’s I’m looking for a more natural alternative. I’m currently taking SmartX. Have only taken it two days thus far. Day 1 (one pill), felt exactly like Vyvanse that lasted a full 5 hours. Day 2 (one pill), I felt nothing. I’m going to continue taking it, but I’m curious to know if anyone has tried OptiMind. I’ve heard a lot of good things and that it’s even “better” than SmartX. mnemosyne <- mnemosyne[mnemosyne$Date>as.Date("2012-05-11") & mnemosyne$Dateactive mind pills|best focus pills active mind pills|best focus supplement active mind pills|best focus supplement for studying
