Deep brain stimulation improves new neuron maturation for memory
Deep brain stimulation (DBS) has traditionally been used to treat movement disorders and more recently some mental health disorders such as certain forms of depression, but research has suggested it can affect learning and memory as well.
Deep brain stimulation (DBS) is a technique traditionally used to treat movement disorders and mental health issues like depression, but recent research suggests it can also enhance learning and memory. Baylor College of Medicine researchers have discovered that DBS targeted to a specific brain area can improve cognitive functions in a mouse model of Rett syndrome, a genetic disorder linked to memory impairments.
The findings, published in the Proceedings of the National Academy of Sciences, demonstrate that DBS stimulates the growth of young neurons in the hippocampus, which are crucial for memory formation. In Rett syndrome, a deficiency in the MeCP2 gene disrupts the development of young neurons, leading to irregular dendritic formation and impaired synaptic function.
Dr. Jianrong Tang, the lead researcher, found that DBS restored the proper structure of young neurons lacking the MeCP2 protein and improved communication between neurons, rebalancing excitatory and inhibitory signaling, both essential for healthy brain activity. However, the study emphasizes that these results are preliminary, based on a mouse model, and further research is required to confirm the safety and effectiveness of similar treatments for humans with Rett syndrome and other intellectual disabilities.
