Supplementary Figure 1
Paired recordings between alx neurons and motoneurons in the high-Ca2+, Mg2+ solution. The pictures (A and C) show images of the recorded cells. A and B, An example of a reliable synapse. This synapse is a mixed one (electrical and chemical). Nine superimposed traces of EPSPs in the motoneurons are shown in each of the solution. The chemical component of the EPSPs is present in the high-Ca2+, Mg2+ solution. Moreover, the latencies, which are constant in each of the solution, do not differ significantly between the control and the high-Ca2+, Mg2+ solution. The amplitude of EPSPs during the chemical component is variable in each of the solutions. C and D, An example of an unreliable synapse. Fifteen superimposed traces of responses in the motoneurons are shown in each of the solution. High-Ca2+, Mg2+ solution increased reliability of the synapses. Note that the latencies are constant in either solution. We examined two more unreliable synapses. The results were essentially the same (no latency change and an increase of reliability).
