Selective serotonin reuptake inhibitors (SSRIs)– These increase serotonin levels in the brain. Popular SSRIs include Prozac, Celexa, Luvox, Lexpro, and Paxil. Selective serotonin & norepinephrine inhibitors (SNRIs)– These medications act on both serotonin and norepinephrine. Brand names include Effe...
Both emotion and sentiment strongly affect our behavior and our attitudes. Emotion is designed to do this; for example our justified pride at a worthy achievement increases attitudes of friendliness and confidence and improves our behavior. Unjustified pride (hubris) however goes hand in hand with...
- Michael Newman will present data from microdialysis studies in rats show- ing that chronically administered T3 increases synaptic levels of serotonin in a dose dependent fashion and reduces the sensitivity of 5-HT1A and 5-HT1B autoreceptors that control serotonin release. A genomic mechanism for...
The first treatment for serotonin syndrome is to stop taking any medication that increases serotonin activity in your body. But be aware: Stopping certain types ofmedications suddenly(like SSRI/SNRIs) can cause other symptoms, too. That’s why it’s important to check in with your healthcare ...
Sensations are the result of information that is received from sensory receptors and interpreted by the brain. Sensory receptors in the peripheral detect and responds to changes in the environment and transduce these changes to electrical impulses. These impulses are carried along dedicated pathway...
What neurotransmitter is involved in drug addiction? How does muscle contraction occur? What neurotransmitter causes mania? How many neurotransmitters are there that act on smooth muscle? What class of neurotransmitter is serotonin? What hormone acts as a stimulus for erythropoiesis?
In summary, while there is some evidence to suggest that creatine supplementation increases water retention, primarily attributed to increases in intracellular volume, over the short term, there are several other studies suggesting it does not alter total body water (intra or extracellular) relative to...
Tetracyclic and tricyclic antidepressants prevent the reuptake of norepinephrine and serotonin into the nerves. It increases the level of norepinephrine and serotonin in the blood. They affect several other chemicals in the brain, thereby increasing the risk of side effects. Hence, they are not genera...
Once the hypothalamus receives a distress signal from the amygdala, it activates a part of the nervous system called the sympathetic nervous system. One of the well-known effects of chronic stress is that it actually increases the size of the amygdala, making the brain more receptive to stress...
This is the official color of optimism and happiness. Maybe that’s why smiley faces are always this color. Studies have shown that the color yellow actually causes the release of serotonin in the brain, which is a chemical that positively stimulates your brain. Basically, it produces “happy...
