Imaging Technique Finds Key Neurons in Brain Interact, May Support More Targeted Treatments

Two key types of brain nerves cells affected by Parkinson’s disease — cholinergic neurons and dopaminergic neurons — communicate and interact via signaling systems, researchers were able to “see” using a new imaging approach. This beneficial neuron-to-neuron interaction, confirmed through the novel approach in a rat model of the…

Rescuing Activity of Specific Neurons Improved Motor Function in Parkinson’s Mice

Rescuing the activity of neurons in the subthalamic nucleus — part of a brain region that controls movement — lessens motor dysfunction in a mouse model of Parkinson’s disease (PD), according to a recent study. The “study argues that the loss of this intrinsic activity promotes abnormal synchronization and…
