The degeneration of dopaminergic neurons is a major contributor to the pathogenesis of mid‐brain disorders. Clinically, cell therapeutic solutions, by increasing the neurotransmitter dopamine levels in the patients, are hindered by low efficiency and/or side effects. Here, a strategy using electromagnetized nanoparticles to modulate neural plasticity and recover degenerative dopamine neurons in vivo is reported. Remarkably, electromagnetic fields generated by the nanoparticles under ultrasound stimulation modulate intracellular calcium signaling to influence synaptic plasticity and control neural behavior. Dopaminergic neuronal functions are reversed by upregulating the expression tyrosine hydroxylase, thus resulting in ameliorating the neural behavioral disorders in zebrafish. This wireless tool can serve as a viable and safe strategy for the regenerative therapy of the neurodegenerative disorders. Degeneration of dopaminergic neurons is a most common age‐related disorder in the central nervous system. A break‐through idea using electromagnetized nanoparticles to mediate neural plasticity and recover the functions of degenerative dopaminergic neurons in the midbrain of a Parkinson's disease animal model is conceived. A significant advance in remote and regenerative cell therapy of the neurodegenerative diseases is thus provided.
