The brain’s rules seem simple: Fire together, wire together. When groups of neurons activate, they become interconnected. This networking is how we learn, reason, form memories, and adapt to our world ...

The human brain contains billions of connected neurons that collectively support different mental functions, including the processing of sensory information, the encoding of memories, attention ...

To think, feel, talk and move, neurons send messages through electrical signals in the brain and spinal cord. This intricate ...

Scientists have made an enormous step toward understanding the human brain by building a neuron-by-neuron and synapse-by-synapse roadmap -- scientifically speaking, a 'connectome' -- through the brain ...

Researchers have mapped and catalogued more than 70,000 synaptic connections from about 2,000 rat neurons, using a silicon chip capable of recording small yet telltale synaptic signals from a large ...

Alzheimer's is a devastating disease that results in memory loss and cognitive decline. It's caused by brain cells dying and the brain itself shrinking from a buildup of proteins. Millions of seniors ...

New research shows that physical pressure from brain tumors or injuries triggers a "self-destruction" program in neurons, leading to irreversible brain damage.

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 ...
