A new study reveals that a receptor called ADGRG1 enables immune cells called microglia to effectively clear these harmful plaques.Read More

Using human postmortem tissue and live brain slice models, scientists showed tau accumulates in both pre- and postsynaptic terminals, likely propagating neuron-to-neuron.Read More

New research shows this region acts like a “reset button,” activating at event boundaries to signal the hippocampus to store distinct memories.Read More
