The muscarinic commissural transmission induced an STP of the contralateral lamina VII glutamatergic inputs but not of the ipsilateral lamina VII glutamatergic inputs. (A) Schema of the experimental procedure (A1). A tungsten electrode was placed on the ventral commissure (CS stim) and another in the ipsilateral lamina VII (ipsi lamina VII stim) to record ipsi lamina VII EPSCs from motoneurons (Mnrec) held at −60 mV, as exemplified by the trace in (A1). (A2) Plot of the mean ipsi lamina VII EPSC area as a function of time before and after CS HFS. No STP was induced in these experimental conditions. (A3) Plot of the mean com-AMPA EPSC area as a function of time before and after a CS HFS in five out of the eight neurons tested in the (A2) condition, showing the induction of com-AMPA EPSC STP in these neurons. (B). Schema of the experimental procedure (B1). Contralateral lamina VII EPSCs (contra lamina VII) were evoked in motoneurons as exemplified by the trace in (B1). (B2) The time course of the mean contra lamina VII EPSC area as a function of time before and after a CS HFS in the absence (black circles) or the presence of atropine (200 μM, gray circles).
