"Discovery: Brain's Nerve Cells Control All Body Movement, Including Breathing"

Researchers have discovered a group of nerve cells in the midbrain that, when stimulated, can halt all forms of movement, including breathing and heart rate. These cells, found in the pedunculopontine nucleus (PPN), express a specific molecular marker called Chx10 and are believed to be involved in focused attention rather than fear. The study's findings may contribute to understanding the motor symptoms of Parkinson's disease, as motor arrest or slow movement is a characteristic feature of the condition. The researchers used optogenetics to stimulate these nerve cells in mice and observe their effects on motor function.
