Definition
The subthalamic nucleus is a key basal ganglia structure providing an excitatory innervation to the globus pallidus and substantia nigra. The spontaneous activity of these neurons is sustained by an autonomous oscillation and interacts with ongoing activity in the external segment of the globus pallidus, with which it has reciprocal connections.
Detailed Description
Why Build a Model of Neurons in the Subthalamic Nucleus?
Interest in models of subthalamic nucleus (STN) neurons is driven by the need to understand pathological oscillations in the basal ganglia seen in Parkinson’s disease and in animal models of the disease (e.g., Bergman et al. 1994) and in the therapeutic mechanism of subthalamic deep brain stimulation. The low-frequency oscillations characteristic of subthalamic cell firing in the disease are not expressed in isolated neurons and so are thought to arise from a network mechanism (e.g., Wilson 2014). A likely mechanism is offered by the reciprocal connections...
