Researchers discover so-called sticky synapses can impair new learning by excessively hard wiring old memories.
A study that used postmortem brain tissue samples from Alzheimer's patients and mouse models found the hunger hormone ghrelin is linked to cognitive impairments and memory loss associated with the disease.
Researchers have developed a new method of reducing the time it takes to grow mini brain models in the lab. This may accelerate research into diseases and injury that affect the nervous system.
A protein associated with Parkinson's disease regulates neurotransmission by self association, a new study reports.
A clusterization approach allows researchers to analyze dendritic spines in new ways.
Researchers have identified a potential new biomarker for cognitive decline associated with Alzheimer's disease. The study reports fibrinogen, a blood clotting protein, causes a series of molecular events that may trigger the destruction of connections between neurons, resulting in cognitive decline.
A new theory of memory visualizes the brain as an organic super-computer that runs complex binary code with neurons acting like mechanical computers. The theory is based on the discovery of the protein molecule, talin, which contains switch-like domains that change shape in response to pressure in mechanical force by a cell.
