New experiments reveal how astrocytes tune neuronal activity to modulate our mental and emotional states. The results suggest ...

Why do we sometimes keep eating even when we're full and other times turn down food completely? Why do we crave salty things ...

To navigate, the brain must convert changing sensations into a map-like sense of the world, which remains stable as the body moves. A new study finds that the fly brain sometimes performs the ...

The light-sensitive tissue of birds’ eyes is not supplied with oxygen by blood vessels – instead, it powers itself with a ...

How do we hear, and how does hearing affect how we play music? These questions are central to the work of Nikolas Alejandro ...

Scientists rebuilt human brain circuits in the lab and discovered that the thalamus acts as a central organizer of cortical wiring. The findings offer new insight into how brain networks form and why ...

Scientists have mapped the sensory neurons in bone for the first time, and identified their dual role in reporting and ...

Navigating the world is no mean feat, especially when the world pushes back. For instance, airflow hitting a fly on its right side can, after a turn, become a headwind. To stay on course, the fly's ...

During brain development, neurons extend long processes called axons. Axons link different areas of the brain and carry signals within it and to the rest of the body. Growing axons "wire up" the brain ...

How do electrical signals become "about" something? Through purely physical processes, neural networks transform activity ...

Researchers documented the activity of neurons that shape directional navigation as bats explored a remote island off the ...

Researchers have developed a way to grow a highly specialized subset of brain nerve cells that are involved in motor neuron disease and damaged in spinal injuries. Their study, published today in ...
