Parkinson’s disease affects brain circuits involved in movement. In this study, scientists investigated how the parafascicular nucleus (PF) in the thalamus and the motor cortex (M1) interacted in rats with Parkinson’s-like symptoms. They found that the firing patterns of PF neurons and the oscillatory activity in M1 were altered in the hemiparkinsonian rats. The neurons […]
Imagine your brain as a bustling city, with different neighborhoods representing various functional networks. Now picture a possible threat to the city’s harmony: subthreshold amyloid-beta (Aβ) deposition, an early marker of Alzheimer’s disease. In this study, researchers explored how the presence of the APOE ε4 allele, a genetic risk factor for AD, influences the relationship […]
Imagine the brain as a complex network of interconnected cities. In a study on essential tremor (ET) recovery after stereotactic radiosurgical thalamotomy, scientists used graph theoretical analysis to examine the structural covariance patterns in the brain. They looked at how cortical thickness, surface area, and mean curvature changed in ET patients before and after the […]
