The neurotransmitter noradrenaline is one of the most abundant in the brain; it has a wide range of effects on attention, wakefulness, stress, blood pressure and heart rate. Now, Scripps Research ...

When your brain needs you to pay attention to something important, one way it can do that is to send out a burst of noradrenaline, according to a new MIT study. This neuromodulator, produced by a ...

Catecholamines, such as dopamine and adrenaline, are hormones produced by the brain, nerve tissues, and adrenal glands. They are responsible for the body’s “fight-or-flight” response. Dopamine, ...

Astrocytes have diverse functions in the brain, but little is known about how the activity of astrocyte networks is regulated. A new study suggests that noradrenaline released during arousal controls ...

Noradrenaline is a neuromodulator secreted in the brain depending on behavioral context and physiological states of animal, influencing a wide range of physiological functions by modulating brain ...

Noradrenaline is a neuromodulator that has been linked to arousal and boosting alertness, but can lead to anxiety in large amounts. Unlike neurotransmitters, which enable cell-to-cell communication, ...

Researchers at the University of Tsukuba investigated whether monoamine neurotransmitters, such as dopamine, are involved in hippocampal activation even during light exercise. Dopamine secreted from ...

A new study suggests that noradrenaline, a neurotransmitter responsible for arousal in the brain, plays a vital role in early sensory perceptions of the world. Being aware of our surroundings is a ...

Norepinephrine is a naturally occurring chemical in the body that acts as both a hormone and neurotransmitter (a substance that sends signals between nerve cells), according to the Endocrine Society.

Noradrenaline is a neuromodulator secreted in the brain depending on behavioral context and physiological states of animal, influencing a wide range of physiological functions by modulating brain ...
