Characteristics of the antidromic responses of VMl neurons to electrical stimulation of the dorsolateral frontal cortex with bipolar surface electrodes or monopolar deep microelectrodes
| Silver ball surface stimulation | Monopolar deep microstimulation | |||
|---|---|---|---|---|
| Threshold (μA) | Latency (msec) | Threshold (μA) | Latency (msec) | Depth (μm) |
| 800 | 3,2 | 120 | 9 | 110 |
| 1700 | 8 | 180 | 10 | 120 |
| 3200 | 10 | 400 | 8 | 110 |
| 1500 | 9 | 400 | 14 | 90 |
| 1500 | 6 | 50 | 11 | 130 |
| 2000 | 14 | 200 | 8 | 110 |
| 2000 | 12 | 400 | 20 | 110 |
| 50 | 9 | 90 | ||
| 250 | 6 | 100 | ||
In each case, the lowest threshold for obtaining a response and its latency are given. In the series of microstimulation, the corresponding depth is presented.
