Musculo-cutaneous (MC) and corticospinal volleys converge on both propriospinal neurones (PN) and feedback inhibitory interneurones (IN) buy generic lopid 300mg online. The thick dashed line indicates that the feedback to inhibitory INs is stronger than to PNs buy discount lopid 300 mg online. Dashed and dotted vertical lines in (c) (placed between the two columns of a pair of open and filled columns with the same latency) indicate the onset of the corticospinal peak and of the inhibition on combined stimulation, respectively.
