Neurons are famously fragile, yet some injured cells manage to hang on, stabilize, and even reconnect. That quiet resilience ...

After injury, the visual system can recover by growing new neural connections rather than replacing lost cells. Researchers ...

This study presents SynaptoGen, a differentiable extension of connectome models that links gene expression, protein-protein interaction probabilities, synaptic multiplicity, and synaptic weights, and ...

For more than a century, neuroscience textbooks have treated damaged neurons in the adult central nervous system as a dead end, especially in the delicate circuitry that carries visual information ...

Elizabeth Jonas first got interested in mitochondria by chance. In 1995, she was a postdoctoral researcher at Yale, working at the Marine Biological Lab in Woods Hole, Massachusetts, where she was ...

A team at Harvard studying the social behavior of mice found that the brain treats isolation and loneliness in much the same way it processes hunger or thirst. Within the hypothalamus, the brain’s hub ...

Researchers have a new hypothesis for how brain cells called astrocytes might contribute to memory storage in the brain. Their model, known as dense associative memory, would help explain the brain's ...

The human brain contains about 86 billion neurons. These cells fire electrical signals that help the brain store memories and send information and commands throughout the brain and the nervous system.
