BETHESDA, MD. (May 30, 2006) – Methylphenidate (Ritalin) elevates norepinephrine levels in the brains of rats to help focus attention while suppressing nerve signal transmissions in the sensory ...

Alzheimer's disease has long been characterized by the buildup of two distinct proteins in the brain: first beta-amyloid, which accumulates in clumps, or plaques, and then tau, which forms toxic ...

Researchers at the University of Pennsylvania School of Medicine have found that the neurotransmitter norepinephrine is essential in retrieving certain types of memories. This represents the first ...

Today, nearly all patients with septic shock receive the same first-line therapy. However, early research suggests that some ...

Methylphenidate (Ritalin) elevates norepinephrine levels in the brain to help focus attention and suppresses nerve signal transmissions in the sensory pathways to help block out extraneous stimuli.

Epinephrine and norepinephrine are neurotransmitters. They deliver signals between nerve cells and hormones. They also feature in medications for cardiovascular problems. Epinephrine and ...

Epinephrine and norepinephrine are very similar neurotransmitters and hormones. Epinephrine has slightly more of an effect on your heart, while norepinephrine has more of an effect on your blood ...

Norepinephrine (NE) and noradrenaline (NA) are two different terms used to describe the same thing. In the United Kingdom, "noradrenaline" is the British-approved name for this neurotransmitter and ...

A sustained state of vigilance will generate a different type of memory than a momentary startle, and these differences are linked to distinct signaling molecules in the brains of mice. Researchers at ...
