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 ...

One of the brain's most celebrated qualities is its adaptability. Changes to neural circuits, whose connections are continually adjusted as we experience and interact with the world, are key to how we ...

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 ...

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

Late-life depression is a major risk factor for Alzheimer's disease, in particular because it accelerates progression from mild cognitive impairment to dementia. How this happens remains largely ...

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

In a groundbreaking achievement, Princeton University scientists have fully mapped the brain of an adult fruit fly, Drosophila melanogaster, unlocking new insights into how brains work. The feat marks ...

Co-written with Jai Liester. Silent synapses represent one of neuroscience's most fascinating discoveries—connections between neurons that lie dormant until activated by specific triggers. 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 ...

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