A study published in Nature has uncovered a new mechanism for how the brain stores emotional memories—one that centers not on neurons, but on astrocytes, the star-shaped glial cells once…
When people experience striking events, not only do those moments become etched in memory, but even seemingly ordinary experiences that occurred shortly before can become unusually vivid. The neural mechanism…
People with attention-deficit/hyperactivity disorder (ADHD) may possess an often-overlooked strength: excessive curiosity. While typically associated with distractibility and hyperactivity, this trait is also closely linked to creativity, adaptability, and a…
Are colors perceived the same way by everyone? A new neuroscience study suggests that, at least on the neural level, the answer may be yes. The question of whether color perception…
For decades, neuroscientists believed that when a person loses a limb, the brain's corresponding sensory region would be “taken over” by neighboring body parts—a process known as cortical reorganization. However,…
Researchers from the University of California, Los Angeles, and Columbia University have discovered that neurons in the brainstem's locus coeruleus act like a “memory reset button”, segmenting continuous experiences into…
A new study published in Nature suggests that replenishing lithium in the brain may prevent, and potentially reverse, Alzheimer's disease. By examining human brain tissue and conducting mouse experiments, researchers…
A study analyzing over 1,000 sleep awakenings has revealed the precise sequence of brain activity as it transitions from sleep to wakefulness—offering new insights that may help combat "sleep inertia,"…
Humans have an innate ability to perceive possible actions in their environment—knowing, for instance, that a path can be walked on or that a lake can be swum in. Despite…
Researchers at the University of Pennsylvania have identified a group of neurons in the hypothalamus that may play a key role in stress-induced sleep and memory disturbances. Published in The…
