Fig 5.

Antiepileptic drugs abbreviate static phase firing. Similar to oxaliplatin (Fig3), afferent responses following acute injection of riluzole and phenytoin fail to maintain repetitive firing during the static phase of muscle stretch (a). Otherwise, IA afferents exhibited normal firing during the dynamic phase of ramp (a) and triangular (b) stretch. Also normal was initial burst firing at onset of ramp (a) and triangular (b) stretch and 1 : 1 firing entrainment to 100 Hz muscle vibration (c).
