BACKGROUND Although a number of clinical and preclinical studies have demonstrated analgesic effects of cannabinoid treatments, there are also instances when cannabinoids have had no effect or even exacerbated pain. The observed pro-nociceptive effects appear to be due to cannabinoid-induced disinhibition of afferent synaptic input to nociceptive circuits.(More)
Abstract Perfusion of Phe-Met-Arg-Phe-NH(2) (FMRFamide), an endogenous neuropeptide, through the gill of Aplysia significantly potentiates the amplitude of the gill withdrawal reflex evoked by tactile stimulation of the siphon with or without the central nervous system present. The potentiating effect of FMRFamide is reversible with washout. FMRFamide(More)
Perfusion of the endogenous neuropeptide, FMRFamide, through the isolated gill of Aplysia facilitated the amplitude of the gill withdrawal reflex (GWR) evoked by tactile stimulation of the gill. The GWR was facilitated in a dose-dependent manner. The facilitation of the GWR produced by FMRFamide perfusion was reversible. In addition to facilitating GWR(More)
