Key result
Continuous intact and afferent vagus nerve stimulation reduced behavioral impairments and inflammatory glial cells in rats with experimentally induced Parkinson's disease.
Why the study?
The effects of vagal afferent- or efferent-selective stimulation on Parkinson's disease using continuous electrical stimulation remained to be determined.
Does continuous vagus nerve stimulation improve behavioral and histological outcomes in rats with experimentally induced Parkinson's disease?

Continuous VNS feasible in rat PD models; leaves open translation of afferent/efferent effects to humans.
Does continuous vagus nerve stimulation improve behavioral and histological outcomes in rats with experimentally induced Parkinson's disease?
Continuous vagus nerve stimulation, specifically via the afferent pathway, promotes neuroprotective and anti-inflammatory effects in a rat model of Parkinson's disease.
Hosomoto et al. (2023) studied Parkinson's disease (experimentally induced). Continuous vagus nerve stimulation (intact, afferent, or efferent) vs. Sham or vagotomy was evaluated on Behavioral impairments in cylinder test and methamphetamine-induced rotation test, and inflammatory glial cells in substantia nigra. Continuous intact and afferent vagus nerve stimulation reduced behavioral impairments and inflammatory glial cells in rats with experimentally induced Parkinson's disease.
