Before revision:  Then, these diversely-recoded signals via parallel-fibers (PFs) from the GR cells are effectively depressed by the error-teaching signals via climbing fibers (CFs) from the inferior olive. Synaptic weights at well-matched PF-Purkinje cell (PC)synapses of active GR cells are strongly depressed via strong long-term depression (LTD) , while practically no LTD occurs at ill-matched PF-PC synapses.
After revision:  Then, these variously-recoded signals are fed into the Purkinje cells (PCs) through parallel-fibers (PFs). In the case of well-matched PF-Purkinje cell (PC)synapses of active GR cells are strongly depressed via strong long-term depression (LTD) , while practically no LTD occurs at ill-matched PF-PC synapses.
