WebNeuron 2024. Purkinje cell dendrites convert excitatory climbing fiber input into signals that instruct plasticity and motor learning. Modulation of … WebClimbing fibers project to Purkinje cells and also send collaterals directly to the deep nuclei. [9] The mossy fiber and climbing fiber inputs each carry fiber-specific information; the cerebellum also receives dopaminergic, serotonergic, noradrenergic, and cholinergic inputs that presumably perform global modulation.

WebThe climbing fiber LTD also results in change in afterhyperpolarization, which can prolong the complex spike pause. Interestingly, the changes induced in calcium transients … WebSep 11, 2024 · In Purkinje cells, long-term potentiation (LTP) of parallel fiber synapses is now well established and it can be achieved with or without climbing fiber signals, making the role of climbing fiber input more puzzling. The central question is how individual Purkinje cells extract global errors based on climbing fiber input. flights from cak to jan
