New research reveals that brain cells use a muscle-like signaling mechanism to relay information over long distances.

The human brain is a complex powerhouse, responsible for orchestrating thoughts, emotions, and memories. Its nerve cells require an immense amount of energy to function. This energy is critical for ...

However, investigating this directly in animal brains is challenging because of the immense complexity of their neural connections and the invasive surgeries that are typically needed. Lab-grown ...

While most of the brain’s neurons are thought to be created before birth, an explosion in neural connections, the myelination of axons, and other developments boost its total volume. Research ...

The human brain is formed by a complex network of neural connections and most of them link neighboring brain regions, which are also the most studied to date. But a recent neuroscientific study by ...

The young neuron also starts making connections with well-established dentate gyrus neurons (blue) as well as neurons in the hippocampus (red). Once connections are formed, mature neurons send signals ...

More than a century later, the puzzle of nervous system organization—the intricately tangled mess that results from each neuron’s connections to thousands of others—remains incomplete. Yet, fully ...
