Light Exercise Boosts Memory via Dopamine and Noradrenaline

New research reveals that even light exercise, like jogging or yoga, activates key neurotransmitter systems that enhance memory by stimulating the hippocampus. In a rat model mimicking human exercise, scientists found that dopamine and noradrenaline levels increased in the hippocampus during low-intensity activity.

Why Do Embarrassing Memories Seem to Surface at Night?

During REM sleep, the locus coeruleus stops releasing noradrenaline. By blocking the cascade, the association between memory and emotional response is broken. This may not occur so frequently in restless sleepers, resulting in rumination and PTSD-like symptoms. For those who usually sleep well, embarrassing feelings experienced at night may be reduced by morning.

Why the Memory of Fear Is Seared Into Our Brains

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.

Practice Really Does Make Perfect

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.
