Adolescence is widely thought to be a time when the brain trims away excess neural connections, refining circuits through synaptic pruning. New research now suggests this view may be incomplete.

For decades, my colleagues and I advanced the premise that early substance use—nicotine, alcohol, or cannabis (or other addicting drugs)—interferes with critical maturation stages, particularly ...

Children exposed to high levels of screen time before age 2 showed changes in brain development that were linked to slower decision-making and increased anxiety by their teenage years, according to ...

For decades, my colleagues and I advanced the premise that early substance use—nicotine, alcohol, or cannabis (or other addicting drugs)—interferes with critical maturation stages, particularly ...

That viral claim that your frontal lobe “isn’t fully developed until 25” turns out to be more myth than milestone. Early brain scans showed that gray matter changes dramatically through the teen years ...

Before age 5, a baby's brain grows rapidly, undergoing a uniquely important moment in development. Yet, many don't understand just how critical it is for setting a person's foundation for thriving.

Scientists have discovered that the adolescent brain does more than prune old connections. During the teen years, it actively builds dense new clusters of synapses in specific parts of neurons. These ...

Researchers from University of California San Diego have found that teenagers who begin using cannabis show slower gains in ...

A study suggesting that the human brain enters a stable phase around age 32 has people in their 20s feeling validated. University of Cambridge neuroscientists released their research results on ...
