Dissecting the neural mechanisms of cerebellum-dependent learning : enhanced plasticity and instructive signals
Abstract/Contents
- Abstract
- The focus of this thesis is to understand the contribution of multiple learning mechanisms to cerebellum-dependent motor learning. The studies that contribute to this thesis examine the role multiple learning mechanisms in the context of signaling in the intact circuit of awake-behaving animals. By using a well-parameterized learning paradigm, it is possible to distinguish and separate the contribution of specific learning mechanisms to different aspects of learning. This thesis demonstrates the sufficiency to two learning mechanisms long hypothesized to be important for cerebellum-dependent learning: 1) LTD at the parallel fiber to Purkinje cell synapse in the cortex (Marr 1969; Albus 1971; Ito 1972); and 2) the output of Purkinje cell simple spike activity (Miles & Lisberger 1981). Furthermore, the findings highlight the importance of understanding how learning mechanisms operate in vivo and interact with the on-going activity as well as previous activity in the circuit to determine different learning outcomes. The idea that the properties of a learning mechanism do not operate in isolation to produce learning but must be considered in the context of the intact and functional circuit is a common lesson that could apply to and should be tested in other learning systems of the brain.
