Figure 6. Mutual facilitation of EPSPs and of IPSPs evoked by uncrossed ipsilateral and crossed contralateral PT fibres.

Figure 6

Averaged (n = 20–30) intracellular records from motoneurones (top traces) and cord dorsum recordings (bottom traces). A, mutual facilitation of EPSPs from the two PTs in a motoneurone after transection of the MLF. B and C, mutual facilitation of IPSPs evoked in two motoneurones, with the MLF intact and after transection of the MLF, respectively. Vertical dotted lines indicate the onset of the PSPs that were facilitated by stimulating both PTs.
