neurons

A new study reveals a network of neurons that, when disrupted, impairs adaptation to new circumstances in several types of dementia.

Researchers identified a novel mechanism by which chemically induced stress is “remembered” by the mitochondria of worms more than 50 generations after the original trigger.

By viewing countless hours of expectorating worms, researchers discover a unique way in which neurons control the movement of muscles.

Injecting oxygen-generating algae into tadpoles allows brain activity to continue in the absence of oxygen, researchers find.

Mice have neurons that connect to both eyes but only propagate the signal from one or the other, simplifying the information sent to the cerebral cortex.

Our perception of quantity, separate from counting or estimation of magnitude more generally, is foundational to human cognition, according to some neuroscientists.

Neurons in the hippocampus store information on the timing of experiences in addition to their content, helping to mediate sequential memory recall, a new study shows.

While exploring suspended animation in mice, scientists discover how an enzyme can protect the brain from dangerously low levels of oxygen.

Some nerve cells in the brains of macaques respond selectively to particular numbers, hinting at a specialized pathway for extracting information about numerical quantity.

Intrigued by an optical illusion he experienced while traveling in Scotland, Robert Addams wrote what is now considered one of the definitive observational accounts of so-called motion aftereffects.

Prolonged exposure to morphine triggers cells in the spine to release signaling molecules that increase pain sensitivity and dull the relief of the drug. Blocking this activity could improve pain management.

Research in mice suggests that moderating nerve activity with drugs or electrical pulses could modify tissue immune responses, curtailing the chronic pain often associated with inflammatory conditions.

The hormone, which is well known for regulating appetite, appears to influence neuronal development—a finding that could shed light on disorders such as autism that involve dysfunctional synapse formation.
