Figure 2From: Nociceptive stimulation induces expression of Arc/Arg3.1 in the spinal cord with a preference for neurons containing enkephalin Several types of nociceptive stimuli induce Arc/Arg3.1 mRNA in the ipsilateral superficial dorsal horn. Histogram showing the number of Arc/Arg3.1 mRNA labeled neurons after each specific nociceptive stimulus. Error bars represent ± SEM.Back to article page
