For more than a century, the story of the brain has been told as a tale of neurons, with every thought and memory traced to their electrical chatter. That narrative is now being rewritten as evidence ...

Scientists rebuilt human brain circuits in the lab and discovered that the thalamus acts as a central organizer of cortical wiring. The findings offer new insight into how brain networks form and why ...

Thinking, learning, feeling—all sensory perceptions are processed in the brain. Roughly 100 billion nerve cells are interconnected in the human brain. The lightning-fast communication between these ...

Synaptic vesicles act as the brain’s chemical couriers, transporting neurotransmitters between cells. When a nerve impulse arrives, these vesicles fuse with the neuron’s membrane and release their ...

As we age, we begin to lose the connections that wire up our brains-and neuroscientists aren't sure why.

Alzheimer’s may destroy memory by flipping a single molecular switch that tells neurons to prune their own connections. Researchers found that both amyloid beta and inflammation converge on the same ...

A study maps how toxic tau disrupts synapses over time, showing early postsynaptic damage that later spreads presynaptically.

Every second, machines like drones, smartphones, and self-driving cars capture floods of visual data. But turning this data into meaning—like recognizing a red light or reading a sign—takes massive ...
