New brain imaging breakthrough reveals clues to Parkinson’s

Johns Hopkins researchers developed a "zap-and-freeze" method that captures rapid communication between brain cells using electrical stimulation followed by instant freezing. Testing on mouse and human brain tissue revealed identical vesicle recycling mechanisms involving the protein Dynamin1xA, confirming that mouse models accurately reflect human brain biology. The breakthrough could help scientists understand nonheritable Parkinson's disease, which affects most patients through disrupted neural communication at synapses, potentially leading to new therapies.
