New insight into how brain makes memories
Every time you make a memory, somewhere in your brain a tiny filament reaches out from one neuron and forms an electrochemical connection to a neighboring neuron.

Neural spines operate like miniature neurons
Nerve cells use a much larger repertoire of data-processing structures than previously thought. Research at LMU and in Regensburg shows that the so-called spines on the dendritic processes of neurons are able to process stimuli ...

Brain scientists figure out how a protein crucial to learning and memory works
Researchers at Johns Hopkins have found out how a protein crucial to learning works: by removing a biochemical "clamp" that prevents connections between nerve cells in the brain from growing stronger. The finding moves neuroscientists ...

Sleep after learning strengthens connections between brain cells and enhances memory
In study published today in Science, researchers at NYU Langone Medical Center show for the first time that sleep after learning encourages the growth of dendritic spines, the tiny protrusions from brain cells that connect ...
