WebMarr and Albus proposed their models in a framework in which the cerebellum controls movements entirely by itself (holistic controlling role). Their models did not consider computational roles played by other brain regions or other parts of the nervous system, except for climbing-fiber inputs. WebMarr’s theory of the cerebellum is characterized by the absence of explicit representation of time and geometrical organization. The statistical nature of model connectivity generates …

WebThe basic concept of the Marr–Albus theory is that the climbing fiber serves as a "teaching signal", which induces a long-lasting change in the strength of parallel fiber inputs. Observations of long-term depression in parallel fiber inputs have provided some support for theories of this type, but their validity remains controversial.
