Reward and Aversion
... The intracranial self-stimulation (ICSS) model is the most common classical method for studying brain stimulation reward (Olds & Milner 1954, Wise 1996) and can be applied either electrically or chemically (Ikemoto & Wise 2004). More than 50 brain sites with reinforcing properties, often reflected b ...

Relationship of Activity in the Subthalamic Nucleus–Globus Pallidus
... One of the functions of the excitatory subthalamic nucleus (STN) is to relay cortical activity to other basal ganglia structures. The response of the STN to cortical input is shaped by inhibition from the reciprocally connected globus pallidus (GP). To examine the activity in the STN–GP network in r ...
