Watching the same dendrites over eight days revealed that the synapses that vanished during hibernation reappeared after arousal and 82 percent of them came back at the same spot on the same dendrite ...

Astrocytes are notoriously two-faced—calmly coddling neurons one minute, then ruthlessly consuming their synapses the next. Why these dramatic mood swings? Blame the EphA4 receptor, according to a ...

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 ...

It takes just a few milliseconds: A vesicle, only a few nanometers in size and filled with neurotransmitters, approaches a cell membrane, fuses with it, and releases its chemical messengers into the ...

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 ...

Researchers from The University of Texas at Dallas' Center for Advanced Pain Studies (CAPS) and their colleagues have made a fundamental discovery about a key mechanism that enables nervous system ...

Preparation of an entire brain for imaging at the necessary resolution requires a distinct set of skills, as does ...

Researchers have completed a detailed map of every neuron and neural connection in the brain of a male fruit fly, creating ...

Fruit flies are excellent research models, in part because it is so easy and inexpensive to raise them, and also because they are so well characterized. The DNA of these insects is estimated to be ...
