Their study included more than 70 volunteers with and without gene mutations that affect the activity of the neurotransmitter chemical dopamine in areas of the brain called the prefrontal cortex and the striatum .
When the neurotransmitter gaba binds to its receptor , the receptor opens and a flood of negatively charged chloride and bicarbonate ions rush into the cell and prevent it from firing .
当gaba神经传递素绑在受体上,受体打开,带负电荷的氯化物和重碳酸盐离子快速进入细胞并阻止抵抗。
Feed her chocolate : it 'll load her up with phenylethylamine , a neurotransmitter that activates the brain 's pleasure center , and caffeine , which can jolt her sex drive .
Throughout the night , levels build up of the neurotransmitter adenosine , and that buildup blocks the function of neurons that make another neurotransmitter , acetylcholine , which is critical for paying attention and learning .
