Correlation between behavior and extracellular dopamine
levels in rat striatum: comparison of microdialysis and fast-scan cyclic voltammetry.
Understanding the dopamine
transporter can lead to new therapies for neurological disorders
Brain cell transplants with fetal dopamine
cells obtained from human embryos have already been performed on a few occasions, with varying results.
The Gouaux lab's more detailed view of the dopamine
transporter structure better reveals how antidepressants act on the transporters and thus do their work.
The extent to which dopamine
rises in the brain after sleep loss may help explain some of the variability in people's abilities to cope with sleep deprivation, Dinges says.
The researchers report the effects of tampering with dopamine
and another chemical messenger, the glutamate neurotransmitter, along the length of the nucleus accumbens of rats.
endocrinologist, Brigham and Women's Hospital in Boston, Mass and consultant medical director, VeroScience, investigated the effects of circadian-timed daily administration of bromocriptine-QR, a potent dopamine
receptor agonist (N=52), versus placebo (N=23) to individuals with type 2 diabetes whose blood glucose levels were poorly controlled on high dose insulin therapy (baseline HbA1c >/= 7.
In one set of experiments, Rice and her colleagues recorded a 20 percent to 55 percent increase in dopamine
released in the striatal region of the rodent brain (where dopamine
's effects on the brain are felt and which governs the body's response to getting a reward).
detection range has been predicted to be 2-11 millimolar.
Serious side effects are caused by current antipsychotic medicines as they cause the complete blockage of dopamine
, explained Rob Lane from the Monash Institute for Pharmaceutical Sciences.
However, with repeated methamphetamine use, dopamine
neurons may degenerate causing neurological and behavioral impairments, similar to those observed in people with Parkinson's disease.
brings feelings of pleasure followed by cravings because of the beer's flavour, not the alcohol it contains.
In this article written and researched by MobileSlots4U, we will look at the reasons behind addiction, in particular the body's reaction to dopamine
, to show that gamblers aren't simply people who have themselves to blame and instead that they are people with a predisposition to addiction in one form or another…
is a neurotransmitter that helps nerve cells pass messages to each other.
The disorders were commoner in those taking drugs that increased the effects of the brain chemical dopamine
