Conflicting results on the existence of new neurons in adults have researchers designing new ways to identify and count neuronal progenitors—and finally get to the bottom of neurogenesis.

Researchers are developing a variety of approaches for clearing neural tissue to get a better view of the brain’s circuitry.

The original experiment found brain activity as measured by fMRI was tied to particular genetic variants.

The new work calls into question the idea that neurons can be genetically engineered to fire in response to magnetic fields, a setback for the budding technique.

Scientists traced 1,000 neurons through the mouse brain, uncovering new details about how the organ is wired.

The glia seem to make up part of a newly described sensory organ, the discoverers suggest.

The Nobel laureate was a proponent of LSD, a consultant for O.J. Simpson’s legal defense, and the creator of a company that infused jewelry with celebrities’ DNA.

Two-photon imaging captures chemical signaling between live mouse neurons on a millisecond timescale.

Some researchers and animal rights groups are amplifying their opposition to an assay that measures how long a rodent tries to stay afloat.

A 3-D printed prosthetic hand moves by reading the signals in forearm muscles.

Johns Hopkins’s Ted Dawson discusses his lab’s demonstration that misfolded α-synuclein can move from the stomach to the brain and cause physical and cognitive symptoms.

The introduced cells engrafted in the nose, became olfactory sensory neurons, and sent axons to the animals’ brains.

Patients in a study of catheter ablation who showed signs of more injury to nerve cells and glia in the heart had fewer symptoms after the treatment.

Algorithms for motion capture help neuroscientists dig into the question of how the brain produces behavior.

A newly developed imaging technology visualizes entire mouse brains in two and three dimensions using multicolor fluorescence microscopy.

Despite doubts last year about human adult neurogenesis, a study shows even 80-year-olds develop new cells in the hippocampus, but such growth is diminished in patients with Alzheimer’s disease.

A new set of engineered receptors responds to an FDA-approved drug to provide the most potent chemogenetic toolkit to date.

Neurons can only efficiently fix genetic injuries when the animals are asleep.

The method combines two approaches to reveal a high-resolution map of all 40 million synapses.
