Researchers have shown in mice that brain cells known as astrocytes are required for a signaling chemical called norepinephrine to modify brain activity, changing the textbook understanding that ...

Delivering a connection-building protein to star-shaped cells in the brain could reverse changes to neural circuits seen in ...

Researchers at Washington University School of Medicine in St. Louis have upended decades-old dogma of how connections between brain cells are rearranged during states of heightened vigilance or ...

The human brain can do many amazing things, but self-repair is not one of its repertoire of abilities. Once neurons die—from trauma, stroke, or disease—they rarely grow back. Scientists have been ...

Healing from any injury involves a delicate balance between scarring and inflammation — two processes that can wreak havoc as well as make repairs. When the injury is to the brain, the balance is that ...

About ten years ago, scientists began exploring an unconventional idea for studying the brain: using bioluminescent light to ...

For the brain to dedicate itself to tasks that need attention, or to respond to unexpected stimuli like a fire alarm, it needs to be able to rewire itself by changing how brain cells communicate. This ...
