Lab-grown brainlike organoids altered with an ancient gene began to look and behave differently. The experiments help show how the human brain has evolved.

Severe cases of COVID-19 can injure the brain in ways that affect memory, thinking and mood for months after the infection is gone, new research hints. It may even raise the risk of Alzheimer's.

Scientists have identified special cells in the human brain that organize movie-like memories, helping us to relive important experiences and events.

Researchers were able to mimic the mind-altering effects of the drug ketamine by inducing a particular rhythm in one area of the brain.

A neurologist who wanted to know how the brain changes in response to a physical disability put his arm in a pink cast for two weeks to find out.

Neuroscientist Barbara Lipska describes in a new memoir surviving 20 brain tumors, and what the eight-week nightmare of psychological symptoms taught her about mental illnesses she's long studied.

The brains of birds and mice continue to produce new nerve cells in the hippocampus throughout life. But research now suggests the human brain stops doing this around adolescence.

Their first epiphanies came during musings over beer, and evolved into a decade of teamwork. Two Harvard researchers explain why they think Alzheimer's disease may be traced to an immunity glitch.

Technology that uses electrical stimulation to tweak the brain may eventually help people with memory problems caused by a brain injury or Alzheimer's disease.

Scientists who identified specific brain cells in mice that control anxiety say the discovery could provide insights that might eventually help people with panic disorder and social phobia.
