Effects of Ca²⁺-free Ringer's solution on bilateral responses induced in MRRN (A) and PRRN (B) RS cells by MLR stimulation. A1, B1, Typical gradual reduction of the synaptic responses recorded from homologous RS cells, ipsilateral (RS ipsi) and contralateral (RS contra) to the MLR stimulation, after switching to Ca²⁺-free Ringer's solution. A2, B2, Graph illustrating the response area in two homologous RS cells as a function of time after changing to Ca²⁺-free Ringer's solution. The recordings from the MRRN and the PRRN were performed in two different preparations.
