Theoretical studies suggest that the solution to the problem involves an adaptive filter, which learns to remove the redundant noise. However, neural learning is also in its infancy and there are still many questions about the stability and application of synaptic learning rules for neural computation. In this thesis, the implementation of an adaptive filter in the brain of a weakly electric fish, A. Leptorhynchus, was studied. It was found to require a cerebellar architecture that could supply independent frequency channels of delayed feedback and multiple burst learning rules that could shape this feedback. This unifies two ideas about the function of the cerebellum that were previously separate: the cerebellum as an adaptive filter and as a generator of precise temporal inputs.enneural computationneural learningplasticityadaptive filternoise cancellationLIFneural modelingneural networkburst learningneuroscienceneurophysicsweakly electric fishneural circuitssensory processingfeedbackspike-timing dependent plasticityburst induced depressionleaky integrate-and-fire modelstochastic modelingThesis
