Induction of CSD and sustained activation of meningeal nociceptors by stimulation of the visual cortex
| Cortical stimulation | CSD per trials | Sustained neuronal activation per CSD |
|---|---|---|
| Electrical | 13/30 (43%) a | 6/13 (46%) |
| Pin prick | 22/24 (92%) | 13/22 (59%) |
| Crystalline KCl | 29/29 (100%) | 12/29 (41%) |
| All trials | 64/83 (77%) | 31/64 (52%) |
aBy design, the parameters of electrical pulses were suboptimal in many trials for inducing CSD in order to control for nonspecific neuronal activation.
