Summary
Wireless cortical stimulation improved gait balance in Parkinson's disease by restoring 38 genes. These genes are key targets for treating motor deficits and enable precise diagnosis and treatment.
Area of Science:
- Neuroscience
- Genetics
- Biomedical Engineering
Background:
- Parkinson's disease (PD) is a prevalent neurodegenerative disorder marked by dopaminergic neuron loss.
- Motor symptoms, like impaired gait and balance, significantly impact patient quality of life.
Purpose of the Study:
- To investigate the efficacy of wireless cortical stimulation in improving motor function in PD.
- To elucidate the molecular mechanisms underlying the therapeutic effects of cortical stimulation using transcriptome sequencing.
Main Methods:
- Wireless cortical stimulation was applied to the primary motor cortex in a PD model.
- Transcriptome sequencing was used to analyze gene expression changes post-stimulation.
- Differentially expressed genes (DEGs) were identified and analyzed for their roles in cellular processes.
Main Results:
- Cortical stimulation significantly improved gait parameters, including step length and velocity.
- 38 differentially expressed genes (DEGs) were identified, with downregulated genes restored to normal levels post-stimulation.
- These DEGs are involved in astrocyte-mediated vascularization and microglia-mediated neuronal clearance, crucial for motor recovery.
Conclusions:
- Wireless cortical stimulation offers a promising therapeutic strategy for Parkinson's disease motor symptoms.
- The identified 38 DEGs serve as potential biomarkers for PD diagnosis and targets for precision medicine.

Digestion begins with a cephalic phase that prepares the digestive system to receive food. When our brain processes visual or olfactory information about food, it triggers impulses in the cranial nerves innervating the salivary glands and stomach to prepare for food.

Neurodegenerative disorders, such as Parkinson's Disease (PD), involve the gradual and irreversible destruction of neurons in particular brain areas. These disorders exhibit standard features like proteinopathies, selective vulnerability of some neurons, and an interaction of intrinsic properties, genetics, and environmental influences in neural injury.

Neurodegenerative disorders are progressive diseases that cause irreversible damage and loss to neurons in specific brain areas. Examples of these disorders include Parkinson's disease, Alzheimer's disease, Multiple Sclerosis (MS), and Amyotrophic Lateral Sclerosis (ALS). These disorders share characteristics such as proteinopathies, selective neuronal vulnerability, and a complex interplay between genetic and environmental factors. The primary therapeutic goal for these conditions is...
