Purkinje cell representations. Purkinje cell (black) receives two classes of inputs: parallel fibers (multi-colored horizontal traces), climbing fibers (green trace). Parallel fibers convey diverse information including but not limited to sensory (continuous traces) and cerebral cortical signals inputs (dash traces). Purkinje cell output encodes multiple motor parameters over multiple timings. The climbing fiber input selects the signals present in the Purkinje cell output. Vertical lines represent spike trains. Continuous lines reflect feedback information, while dashed lines reflect predictive information. The transparency reflects the timing of the information conveyed (no transparency – short range, high transparency – long range). In the diagram, different colors represent different streams of information.
