Excitatory

Those that make you feel energized, excited, and stimulated, and help you focus, learn, and remember, are called excitatory neurotransmitters. ❋ M.D. Mark Hyman (2009)

The majority of brain cells are called excitatory because they ramp up the action of target cells. ❋ Unknown (2010)

That said, it is part of the joy of popular science writing that it can lead one to the point of comprehending sentences such as: "These findings with MK-801 pretreatment suggested that LTP and/or LTD of the excitatory synapses received by the neurons of the VTA was induced in rats as a result of taking cocaine." ❋ Unknown (2011)

In later work, which got little attention in the West, Pavlov sought to prove that dogs are of four temperamental types, "strong excitatory," "lively," "calm imperturbable, or phlegmatic," and "weak inhibitory." ❋ Unknown (2009)

Progesterone administration attenuates excitatory amino acid responses of cerebellar Purkinje cells. ❋ T.S. Wiley (2010)

Glutamate accelerates brain activity—it is excitatory. ❋ M.D. Henry Emmons (2010)

Chronic stress raises the level of the excitatory hormones, including norepinephrine and cortisol, which can wear your body down and lead to disease. ❋ M.D. Nicholas Perricone (2010)

There are two main families of neurotransmitters in the brain: the excitatory neurotransmitters like adrenaline and the calming neurotransmitters like GABA (gamma amino butyric acid). ❋ Unknown (2010)

Then, drinkers boost their intake in order to achieve the intoxication they enjoyed before, and their inhibitory and excitatory messenger substances become permanently unbalanced. ❋ Carol Sklenicka (2009)

The major neurotransmitters in the brain are glutamate, an excitatory neurotransmitter, and gamma-aminobutyric acid GABA, an inhibitory neurotransmitter. ❋ KELLY TRAVER (2009)

Second, small partially digested food proteins, called peptides, from gluten and casein can act to disturb the normal neurotransmitter function in the brain, and third, they can act as “excitotoxins,” increasing glutamate an excitatory neurotransmitter and creating a chain reaction that overexcites, injures, inflames and ultimately kills brain cells. ❋ M.D. Mark Hyman (2009)

When you have low levels of GABA, it is harder for you to relax after your body has released these excitatory neurotransmitters. ❋ M.D. Mark Hyman (2009)

It is best to start with the inhibitory neurotransmitter support (serotonin and GABA) and then after a week or two move to the excitatory support (dopamine and acetylcholine). ❋ M.D. Mark Hyman (2009)

These chemicals are excitatory hormones, neurotransmitters that get our bodies ready for dangerous situations which was the original purpose of the anxiety response. ❋ M.D. Mark Hyman (2009)

Inflammatory messenger molecules called cytokines such as interferon gamma INF γ stimulate the enzymes TDO and IDO, which break down tryptophan and force it into a pathway that makes the excitatory neurotransmitter glutamate, which kills brain cells. ❋ M.D. Mark Hyman (2009)

Interestingly, a 2008 study from the Corvallis Psychiatric Clinic in Oregon showed that using amber-tinted glasses blocked the excitatory blue spectrum of light commonly encountered during television and computer viewing. ❋ Woodson Merrell (2008)

It also helps block the excitatory NMDA receptors in the brain, which is part of the explanation for its ability to calm some people. ❋ Woodson Merrell (2008)

Unlike ashwaganda and cordyceps, Rhodiola can be overly excitatory. ❋ Woodson Merrell (2008)
