Criteria for the classification of synaptic responses
| Classification | Threshold | Monosynaptic (Fixed latency) | Polysynaptic (Variable latency) | Latency |
|---|---|---|---|---|
| Aβ mono | <50 μA | + | <2.2 msec | |
| Aβ poly | <25 μA | + | ||
| Aδ mono | >25 μA | + | 2.2–10 msec | |
| Aβ/Aδ poly | 25–50 μA | + | ||
| Aδ poly | >50 μA | + | ||
| C mono | >200 μA | + | 20–40 msec |
