Spreading depression: Effects of applying potassium chloride to the dura of the rabbit on the conditioned nictitating membrane response

The nictitating membrane response of the rabbit was conditioned to an auditory CS with infra-orbital shock as the US. Following conditioning, Ss were divided into two groups to receive application to their exposed dura of either physiological saline or potassium chloride (KCl). Saline had no detectable effects, whereas KCl crystals blocked the occurrence of CRs for about 100 min. and was followed by recovery to approximately 70% of their initial level after 254 min.
