Surprising events trigger the release of noradrenaline in the brain, helping to focus attention and learn from the experience.
Norepinephrine facilitates fear processing by stimulating a population of inhibitory neurons in the amygdala, generating repetitive bursting patterns of electrical activity. This activity changes the frequency of oscillations in the amygdala from resting state to aroused state, promoting the formation of fear memories.
Neuron activity in the locus coeruleus spikes when a mother mouse touches her pup to retrieve it.
A new framework describes how the locus coeruleus regulates the brain's sensitivity to relevant information during situations that require attention.
Researchers have found a direct connection between flavan 3-ols consumption and fat browning by activation in the sympathetic nervous system. The findings could help in the development of new treatments for obesity-related disorders.
The old adage that practice makes perfect may very well be true, according to neuroscientists. Researchers found when a male zebra finch is in the presence of an attractive female and delivers its rehearsed mating call, a noradrenaline release in the basal ganglia shuts down variability in song and makes the call as perfect as it can be.
Noradrenaline impairs immune response by inhibiting the movement of leukocytes to different tissue.
Motor learning deficits associated with autism may be the result of reduced levels of noradrenaline release in the primary motor cortex.
In times of uncertainty, noradrenaline helps us learn and adapt our behaviors, researchers report.
Microglia play a critical role in reorganizing neural connections, fighting infections, and repairing damage to neurons while we sleep.
Researchers have identified a neural circuit in the brain of fruit flies that help them perform to their best ability while searching for food.
Noradrenaline is essential for astrocytes to respond to local stimulation.
