Star cells in the brain render memory flexible
As we live in a dynamically changing environment, it is important for our brain to not only learn new things but also to modify existing memories. This is commonly referred to as "cognitive flexibility." Without this ability, ...

Call-and-response circuit tells neurons when to grow synapses
Brain cells called astrocytes play a key role in helping neurons develop and function properly, but there's still a lot scientists don't understand about how astrocytes perform these important jobs. Now, a team of scientists ...

How an enriched environment fires up our synapses
Processing of sensory impressions and information depends very much on how the synapses in our brain work. A team around chemist Robert Ahrends from the University of Vienna and neuroscientist Michael R. Kreutz from Leibniz ...

Neurobiologists identify widely used assembling and stabilizing forces behind brain synapses
Within the brain and other parts of the nervous system, synapses are key junctional points in between neurons (the nerve cells) where critical signals are transmitted. More specifically, the "glutamatergic" synapses are the ...

Researchers discover key mechanisms behind synapse degeneration in Alzheimer's brain
Healthy adult brains are endowed with a vast number of synapses, structures that relay signals across nerve cells to enable communications, information processing and storage throughout the nervous system. Apart from dynamic ...
