Researchers Call for New Studies to Learn How Our Brains Change When We’re Awake After Midnight

A new hypothesis suggests when people are awake during the biological circadian night there are neurophysiological changes in the brain that alters the way in which we interact with the world, especially when it comes to impulse control, information processing, and reward processing.

Children Who Lack Sleep May Experience Detrimental Impact on Brain and Cognitive Development That Persists Over Time

Children who sleep less than 9 hours per night have significant differences in brain regions associated with memory, intelligence, and well-being compared to their peers who sleep 9 or more hours per night. Less sleep in children was also associated with increased risks of depression, anxiety, and impulsive behaviors.

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.

Even in Sleep, Your Brain’s Neurons Are Humming Along to Mozart

A study of the cerebral cortex discovered there is a robust response to sound during sleep that largely mirrored the brain's response during wakefulness. However, differences in brain waves that help the brain understand sound and anticipate what comes next is missing during sleep.

Sleep Provides a Major Key to the Mystery of Consciousness

During sleep, the brain analyzes auditory input but is unable to focus on the sound or identify the noise; therefore no conscious awareness of the stimuli occurs.
