Before revision:  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:  Synaptic weights at well-matched PF-Purkinje cell (PC)synapses of active GR cells are strongly depressed through strong long-term depression (LTD) , while practically no LTD occurs at ill-matched PF-PC synapses.
