Brain activity during vocalizing in small parrots — called budgerigars or parakeets — shows a similar pattern to what’s seen in people.
Sunlight's peak intensity is at a green wavelength. Here’s why it doesn’t appear that way to us.
Brain injuries, drug use and other factors can impair our memory. But targeted practice and healthy habits can boost our ability to remember.
Over eight years, the mass of microplastics in human brains increased by some 50 percent. There are growing hints that internal microplastics may harm us.
A teen researcher identified a possible link between brain development and mental health in young trans people.
Neurons in the brain forge new connections and sometimes trim back old ones. This capacity for change allows us to learn new skills and recover from injury.
Our autonomic nervous system balances two natural responses. If stressed or overwhelmed, simple techniques can help to restore that balance.
Robotic devices like this might someday help musicians, gamers, athletes or even surgeons improve their dexterity.
Tissue from the memory centers of people’s brains reveal relatively few links among nerve cells in the hippocampus. But they carried strong, reliable signals.
