Adolescent brains are especially vulnerable to risk-taking and social pressure. But there are steps parents can take to steer their teen away from dangerous social media stunts.
Of the risks posed by AI, overtaking human intelligence isn’t an immediate concern.
Some people don’t have the ability to create mental images, a condition called aphantasia, but can still experience visual imagery in their dreams.

Learning new rules requires the suppression of old ones. A better understanding of the brain circuits involved in behavioral adaptation could lead to new ways to treat schizophrenia and bipolar disorder.
Neuroscientists have typically thought of energy supply to the brain as demand-based. A supply-limited view offers another perspective toward aging and why multitasking can be difficult.
Parents provide the energy needed for their young to grow large brains. Climate change may negatively affect birds’ brain development as it impacts food supplies.
