Researchers identify how cells control calcium influx
(Medical Xpress)—When brain cells are overwhelmed by an influx of too many calcium molecules, they shut down the channels through which these molecules enter the cells. Until now, the "stop" signal mechanism that cells ...

Blue Brain Project accurately predicts connections between neurons
One of the greatest challenges in neuroscience is to identify the map of synaptic connections between neurons. Called the "connectome," it is the holy grail that will explain how information flows in the ...

Research finds key molecules involved in forming long-term memories
How does one's experience of an event get translated into a memory that can be accessed months, even years later? A team led by University of Pennsylvania scientists has come closer to answering that question, identifying ...

Even in fruit flies, enriched learning drives need for sleep
Just like human teenagers, fruit flies that spend a day buzzing around the "fly mall" with their companions need more sleep. That's because the environment makes their brain circuits grow dense new synapses and they need ...

Newly found 'volume control' in the brain promotes learning, memory
Scientists have long wondered how nerve cell activity in the brain's hippocampus, the epicenter for learning and memory, is controlled—too much synaptic communication between neurons can trigger a seizure, and too little ...

How connections in the brain must change to form memories could help to develop artificial cognitive computers
Exactly how memories are stored and accessed in the brain is unclear. Neuroscientists, however, do know that a primitive structure buried in the center of the brain, called the hippocampus, is a pivotal region ...

Alzheimer's disease is associated with removal of the synaptic protein ADAM10
Alzheimer's disease is characterized by the accumulation of neurotoxic β-amyloid peptide (A-beta). ADAM10, a protein that resides in the neural synapses, has previously been shown to prevent the formation of A-beta.
