Study links LOUD SOUNDS to dopamine neuron damage, triggering symptoms similar to Parkinson’s disease
A study has found that exposure to loud noises (85–100 decibels) for just one hour a day accelerates neurodegeneration in Parkinson’s-prone mice, causing motor dysfunction similar to human PD progression. Chronic noise exposure activates a neural pathway between the sound-processing inferior colliculus (IC) and dopamine-producing substantia nigra pars…
