Evoked potentials in the Atlantic cod following putatively innocuous and putatively noxious electrical stimulation: A minimally invasive approach
Aspects of peripheral and central nociception have previously been studied through recording of somatosensory evoked potentials (SEPs) to putative noxious stimuli in specific brain regions in a few freshwater fish species. In the present study, we describe a novel, minimally invasive method for reco...
