WASHINGTON — Thanks to a mouse watching clips from “The Matrix,” scientists have created the largest functional map of a brain to date — a diagram of the wiring connecting 84,000 neurons as they fire ...

The work reveals that the brain — in mice and, presumably, in humans — is actively involved in the development of endurance, the ability to get better at a physical activity with repeated practice, ...

Aging doesn’t have to mean losing your past. Scientists have found a way to "reprogram" specific memory-holding neurons, ...

Through a combination of human NSC analysis in the lab and mouse model experiments, the researchers singled out a protein ...

Exercise does more than strengthen muscles; it also rewires the brain. In a study published in Neuron, researchers reveal that the lasting gain in endurance from repeated exercise—such as the ability ...

Scientists have reversed severe memory loss in two mouse models of Alzheimer’s by restoring the brain’s energy supply. Late-stage mice showed brain tissue repairing itself once fuel balance returned, ...

Axonal boutons are specialized endings of an axon, which is the long slender part of a neuron that connects neurons by transmitting neural signals. These are sites where synapses form, allowing ...

After more than a decade of studying threadlike connections between neurons in petri dishes, scientists now have evidence they exist in the brain, too. By making mouse brains see-through, Hyung-Bae ...

New research challenges the century-old practice of mapping the brain based on how tissue looks under a microscope. By analyzing electrical signals from thousands of neurons in mice, scientists ...

Two-photon microscopy captures axonal segments in a living brain, enabling researchers to quantify structural changes in specialized areas under noninvasive low-intensity repetitive transcranial ...

Breakthroughs, discoveries, and DIY tips sent six days a week. Terms of Service and Privacy Policy. One of the brain’s most important properties is its flexibility ...
