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

When researchers injected mice with antibodies from fibromyalgia patients, the animals developed symptoms of the disease—suggesting that it may be controlled by the immune system, not the nervous system.

So-called mossy fiber synapses in the hippocampus can meter the amount of neurotransmitter they receive by sending glutamate against the usual direction of synaptic flow.

In an unexpected twist in neuroscience dogma, the cells on the receiving end of neurotransmission appear to be able to release glutamate to regulate the transmitting cell’s activity.

Understanding how the brain coordinates electrical activity could be key to developing more-effective treatments for a variety of brain disorders.

In mice, epigenetic marks made on histones during infancy influence depression-like behavior during adulthood. A drug that reverses the genomic tags appears to undo the damage.

The University of Alabama at Birmingham neuroscientist aims to determine which cells are most important in prompting the disease’s initiation and progression.

The results are a proof-of-concept that the novel coronavirus can replicate in neurons, but it’s too soon to say whether this occurs in people with COVID-19.

The activation of young brain cells in adult mice is necessary not just for forming memories, but consolidating them during rapid eye movement sleep, a study shows.

The Yale neuroscientist seeks to understand the brain’s architecture and function using C. elegans.

The symptoms suggest SARS-CoV-2 might infect neurons, raising questions about whether there could be effects on the brain that play a role in patients’ deaths, but the data are preliminary.

The silicon chips receive and send electrical signals, recreating activity from neurons in the rat brain that play a role in breathing and thinking.

Organelles isolated from two types of neurons and a nonneuronal astrocyte in the mouse cerebellum showed varying levels of proteins, hinting at functional differences.

A study finds variations in the levels of proteins for some important processes among organelles from different brain cells.

A major sensory neuron in roundworms distinguishes proprioception from harmful touch by sending out local or whole-cell signals, respectively.

New, unpublished results show some of the cells produce new neurons for up to 90 days, much longer than a previously identified set of neural stem cells that only generate neurons for a month or two.

The Francis Crick Institute neurobiologist aims to learn how physiological states, such as hunger, alter information processing in the brain.
