Adrenaline packs a powerful punch in the use of antidepressants
... reuptake inhibitors (which work by increasing the synaptic
activty of adrenaline in the brain); and selective serotonin reuptake inhibitors (which elicit their effects by increasing the activity of serotnin in the brain). Previously, it was believed that SSRIs whose over-the-counter names include Prozac, Z...
How a dietary supplement can protect against Alzheimer's disease
...D can act synergistically to quantitatively reduce synaptic
proteins, specifically, dendritic scaffold proteins, that are critical for cognition as evidenced by memory deficits observed in the Morris water maze paradigm," wrote the researchers. "The results show a dramatic impact of diet on the expression of ...
Tuberculosis drug combined with virtual reality therapy is effective in treating fear of heights
...nces. Because it was known that DCS improves NMDA synaptic
transmission and we found it improved extinction in rats, we hoped to facilitate the effects of cognitive behavioral therapy by combining DCS with virtual reality therapy in humans. Our results demonstrate that this combination is effective, and tha...

Brain's nicotine receptors also target for anti-depressants
...e past several decades has been drugs that inhibit synaptic
reuptake of monoamine neurotransmitters. Recent evidence indicates other neurotransmitter systems might play a role in the mechanism of action of antidepressants, Picciotto said. In this study in mice, she and her colleagues tested the action of anti...

Potential treatment for Fragile X Syndrome demonstrated in fruit fly model
...t Fragile X patients have a tendency to break down synaptic
connections (sites used for neuron to neuron communication) more readily than the general population. This breakdown is due to an increased activity in the metabotropic glutamate receptor (mGluR), which is located on the surface of neurons, including...
