  • This is your brain on fried eggs: Brain, motivation and eating a high-fat diet - Science Daily, 7/14/15 - "Fulton's study is the first of its kind to show that, regardless of weight changes, unrestrained intake of saturated fats can have negative effects on the controls of motivation by the brain. "As we were able to control for changes in body weight, hormones and glucose levels, we think that the fats may be affecting the dopamine system by a direct action in the brain," Fulton said. "We in fact have separate evidence that brain inflammation could be involved in this process, as it is evoked by saturated high-fat feeding"
  • Omega-3 reduces ADHD symptoms in rats - Science Daily, 8/23/13 - "The results show a clear improvement in ADHD-related behaviour from supplements of omega-3 fatty acids, as well as a faster turnover of the signal substances dopamine, serotonin and glutamate in the nervous system ... The new findings indicate that ADHD has a biological component and that the intake of omega-3 may influence ADHD symptoms ... we have without a doubt found molecular changes in the brain after rats with ADHD were given omega-3 ... We saw that the turnover of dopamine and serotonin took place much faster among the male rats that had been given omega-3 than among those that had not. For serotonin the turnover ratio was three times higher, and for dopamine it was just over two and a half times higher" - See Mega Twin EPA at Amazon.com and Jarrow Max DHA at Amazon.com.
  • Ginkgo biloba leaf extract (EGb 761®) and its specific acylated flavonol constituents increase dopamine and acetylcholine levels in the rat medial prefrontal cortex: possible implications for the cognitive enhancing properties of EGb 761® - Int Psychogeriatr. 2012 Aug;24 Suppl 1:S25-34 - "As seen for isorhamnetin, the effect on neurotransmitter levels seems not to be a general effect of flavonols but rather to be a specific action of acylated flavonol glycosides which are present in EGb 761®. The direct involvement of these two flavonol derivatives in the increase of dopaminergic and cholinergic neurotransmission in the prefrontal cortex may be one of the underlying mechanisms behind the reported effects of EGb 761® on the improvement of cognitive function" - See Ginkgo biloba at Amazon.com.
  • Antioxidative and Anti-Inflammatory Protection from Carnosine in the Striatum of MPTP-Treated Mice - J Agric Food Chem. 2010 Oct 6 - "The preintake of carnosine significantly attenuated MPTP-induced glutathione loss, retained the activity of GPX and SOD, diminished oxidative stress, and lowered inflammatory cytokines and nitrite levels as well as suppressed iNOS activity (P < 0.05). MPTP treatment significantly suppressed GPX mRNA expression and enhanced iNOS mRNA expression (P < 0.05). Carnosine preintake significantly elevated GPX mRNA expression and declined iNOS mRNA expression (P < 0.05). Preintake of carnosine also significantly improved MPTP-induced dopamine depletion and maintained 3,4-dihydroxyphenylacetic acid and homovanillic acid levels (P < 0.05). These results suggest that carnosine could provide antioxidative and anti-inflammatory protection for the striatum against the development of Parkinson's disease" - See carnosine products at Amazon.com.

News & Research:

  • Long-Term Cannabis Use May Blunt the Brain's Motivation System - Science Daily, 7/1/13 - "Long-term cannabis users tend to produce less dopamine, a chemical in the brain linked to motivation ... The researchers used PET brain imaging to look at dopamine production in the striatum of 19 regular cannabis users and 19 non-users of matching age and sex ... The lowest dopamine levels were seen in users who meet diagnostic criteria for cannabis abuse or dependence"
  • Feel-good hormone helps jog memory, finds study of seniors - Science Daily, 11/8/12 - "Half of the test participants had first taken a placebo and the remainder had taken Levodopa. This substance, also known as L-DOPA, is able to reach the brain from the bloodstream, and there it is converted into dopamine ... after six hours memory performance changed. Test subjects with Levodopa recognised up to 20 per cent more photos than the members of the comparison group. The ratio between the amount of Levodopa taken and the body weight of the test subjects proved to be decisive for an optimal dose" - Yeah but I think if I remember correctly, you buildup a tolerance to Levodopa and it no longer works.  IAS sells it.
  • Dopamine impacts your willingness to work - Science Daily, 5/1/12 - ""go-getters" who are willing to work hard for rewards had higher release of the neurotransmitter dopamine in areas of the brain known to play an important role in reward and motivation, the striatum and ventromedial prefrontal cortex. On the other hand, "slackers" who are less willing to work hard for a reward had high dopamine levels in another brain area that plays a role in emotion and risk perception"
  • Dopamine system in highly creative people similar to that seen in schizophrenics, study finds - Science Daily, 5/18/10
  • Ritalin boosts learning by increasing brain plasticity - Science Daily, 3/7/10 - "Ritalin boosts both of these cognitive abilities by increasing the activity of the neurotransmitter dopamine deep inside the brain. Neurotransmitters are the chemical messengers neurons use to communicate with each other. They release the molecule, which then docks onto receptors of other neurons. The research demonstrated that one type of dopamine receptor aids the ability to focus, and another type improves the learning itself"
  • The Ginkgo biloba extract EGb 761((R)) and its main constituent flavonoids and ginkgolides increase extracellular dopamine levels in the rat prefrontal cortex - Br J Pharmacol. 2010 Jan 25 - "A single oral dose of EGb 761 (100 mg.kg(-1)) had no effect on monoamine levels. However, following chronic (100 mg.kg(-1)/14 days/once daily) treatment, the same dose significantly increased extracellular dopamine and noradrenaline levels, while 5-HT levels were unaffected. Chronic treatment with EGb 761 showed dose-dependent increases in frontocortical dopamine levels and, to a lesser extent, in the striatum. The extracellular levels of HVA and DOPAC were not affected by either acute or repeated doses. Treatment with the main constituents of EGb 761 revealed that the increase in dopamine levels was mostly caused by the flavonol glycosides and ginkgolide fractions, whereas bilobalide treatment was without effect. Conclusions and implications: The present results demonstrate that chronic but not acute treatment with EGb 761 increased dopaminergic transmission in the PFC. This finding may be one of the mechanisms underlying the reported effects of G. biloba in improving cognitive function" - See Ginkgo biloba at Amazon.com.

  • Citicoline affects appetite and cortico-limbic responses to images of high-calorie foods - Int J Eat Disord. 2009 Mar 3 - "Cytidine-5'-diphosphocholine (citicoline) has a variety of cognitive enhancing, neuroprotective, and neuroregenerative properties. In cocaine-addicted individuals, citicoline has been shown to increase brain dopamine levels and reduce cravings ... After 6 weeks, there was no significant change in weight status, although significant declines in appetite ratings were observed for the 2,000 mg/day group. The higher dose group also showed significant increases in functional brain responses to food stimuli within the amygdala, insula, and lateral orbitofrontal cortex. Increased activation in these regions correlated with declines in appetite ratings ...These preliminary findings suggest a potential usefulness of citicoline in modulating appetite, but further research is warranted" - See citicholine at Amazon.com.

  • Insulin's Brain Impact Links Drugs And Diabetes - Science Daily, 10/17/07 - "The researchers then restored insulin by pulsing the hormone back into the brain of the diabetic animals and found that the system returns to normal, indicating that the lack of insulin in the striatum directly affected amphetamine action"
  • Antidepressant-Like Effect of Cordyceps sinensis in the Mouse Tail Suspension Test - Biol Pharm Bull. 2007 Sep;30(9):1758-62 - "Cordyceps sinensis (CS) has been known as a component of traditional medicines that elicit various biological effects such as anti-fatigue, immunomodulatory, and hypoglycemic actions. Since it has been well-established that fatigue is closely related to depression, we used the tail suspension test (TST) in mice to examine the antidepressant-like effects of hot water extract (HWCS) and supercritical fluid extract (SCCS) of CS ... these results suggest that SCCS may elicit an antidepressant-like effect by affecting the adrenergic and dopaminergic systems, but not by affecting the serotonergic system" - See cordyceps at Amazon.com.

  • Sex, Sexuality, and Serotonin - Medscape, 7/20/04 - "From our study of the brain, we have some nice evidence that elevated activity of dopamine is involved in that intense sense of passion and arousal of romantic love. I also maintain in my book, Why We Love, that we're going to find out sometime that norepinephrine is also involved, largely because heightened activity of norepinephrine is also associated with focused attention, elevated energy, motivation to win a reward, elation, and 2 characteristics of romantic love -- obsessional following and object imprinting ... low activity levels of serotonin are going to be involved"
  • Reduction of Brain Dopamine Concentration With Dietary Tyrosine Plus Phenylalanine Depletion - Am J Psychiatry 160:1887-1889, October 2003 - "Healthy male subjects were scanned on two occasions: once after receiving a balanced amino acid drink and once after receiving a drink mixture from which tyrosine and phenylalanine were omitted ... Dietary tyrosine and phenylalanine depletion increased [11C]raclopride binding in the striatum by a mean of 6%. The change in [11C]raclopride binding correlated significantly with the fall in the ratio of tyrosine and phenylalanine to large neutral amino acids"

  • Phosphatidylserine (PS) The Essential Brain Nutrient - Life Extension Magazine, 9/02 - "Among its list of functions, phosphatidylserine stimulates the release of dopamine (a mood regulator that also control physical sensations, and movement), increases the production of acetylcholine (necessary for learning and memory), enhances brain glucose metabolism (the fuel used for brain activity), reduces cortisol levels (a stress hormone), and boosts the activity of nerve growth factor (NGF), which oversees the health of cholinergic neurons"
  • Testosterone Deficiency & Depression, Does DHEA Raise the Levels of Bioavailable Testosterone in Men? - Life Extension Magazine, 8/02 - "The mood-improving action of testosterone is more likely to be due to the direct action of testosterone on the brain-possibly through raising the levels of dopamine, a very important "reward" neurotransmitter"
  • Depression Linked to Parkinson's - WebMD, 5/28/02 - "About 1.4% (19) of the depressed people (about 1.4%) developed Parkinson's compared with only 0.4% of the others ... the link may have a biological explanation, known as the "serotonin hypothesis." Not only do people with Parkinson's disease have lower levels of dopamine in the brain, studies have also shown that the brains of these patients also have reduced levels of another brain chemical, serotonin. Low levels of serotonin are known to be a key factor in depression" - Note: St. Johns wort is believed to increase all three of the brain's primary chemicals, serotonin, norepinephrine and dopamine.

  • Parkinson's Defense - Nutrition Science News, 5/01 - "In vitro studies support the theory that vitamins C and E suppress oxidative destruction of dopamine ... One approach has been to increase internal dopamine levels by molecules that occur naturally in the body, such as nicotinamide adenine dinucleotide (NADH) and cytidinediphosphocholine (CDP-choline). Another strategy has been Co-Q10 therapy to prevent mitochondrial oxidative damage that occurs in PD patients ... CDP-Choline (citicholine) occurs in the body and is closely related to choline, a nutrient in the B-vitamin family. Some evidence suggests citicholine may enhance the effects of L-dopa, possibly by increasing dopamine levels in the brain"

  • 5-HTP : The Natural Way to Overcome Depression, Obesity, and Insomnia - Dr. Murray - "either L-tyrosine or D,L-phenylalanine used alone produced improvements in mood comparable to those seen with antidepressant drugs, but without the side effects (Table 2.7)." The reason appears to be that tyrosine and phenylalanine have many roles in the body. Besides being converted to dopamine and norepinephrine, they can be converted to other substances that have stimulant and mood-elevating properties. Phenylalanine (both in its D- and L-forms) increases the level of phenylethylamine (PEA), while L-tyrosine increases the levels of PEA and two other neurotrans-mitters, octopamine and tyramine. These compounds have stimulant and mood-elevating properties, and depressed patients have been found to have low levels of them."
